Core Calls

The DuraMAT Core Call process will grow DuraMAT's expertise, tools, and access to facilities while contributing key results that will help to increase PV module reliability and performance.

DuraMAT Core Call Process — Annual Submission Review


The DuraMAT Consortium brings together DOE national lab and university research capabilities with the photovoltaic (PV) and supply-chain industries to accelerate a sustainable, just, and equitable transition to zero carbon electricity generation by 2035 through our five core objectives: development of a central data resource for PV modules, multi-scale and multi-physics modeling, disruptive acceleration science, forensic tools for fielded modules, and materials solutions for more durable, reliable, and resilient modules. DuraMAT leverages the decades of experience, expertise, and world-class facilities at the national laboratories to create a “one-stop-shop” for timely solutions to critical barriers limiting module reliability and durability. In its first five years, DuraMAT has become a trusted partner for the US industry.

The core objectives have been defined in partnership with DuraMAT’s Industry Advisory Board (IAB) and are long term research objectives that are expected to continue through DuraMAT 2. Selection and funding of specific projects however are dynamic, allowing the consortium the flexibility to address the most current and pressing industry concerns. DuraMAT funding supports research projects through a number of different competitive processes described in this TWP. All of the core objectives are focused on the DuraMAT goal of accelerating a sustainable, just and equitable transition to zero carbon electricity generation by 2035 by addressing these two questions:

  1. Which materials and module designs will enable sustainable, high energy yield 50-year modules, and how do we ensure that these new modules are not going to fail prematurely?
  2. What triggers wear out, defined as a rapid increase in degradation at end of life, and what are the characteristics, rates, and mechanisms of long term degradation in PV modules?

In close collaboration with the IAB, DuraMAT 2 has identified understanding which materials and packaging designs will enable high energy yield modules with the potential for 50-year lifetimes and identifying long term degradation mechanisms and wear out failures as our highest priorities. Building confidence in 50 year modules requires an understanding of early failures and end of life wear out. Our planned work in DuraMAT 2 includes:

  • De-risking high yield modules and screening them for weaknesses that lead to early failure
  •  Identifying the triggers and dominant contributors to wear out failures
  • Understanding the role of polymeric materials in wear out and long term degradation
  • Continued study of bifacial modules, glass glass packaging, and impacts of high energy yield module design
  • Continued development of new accelerated testing methods, modeling approaches, and scalable forensics
  • Development of materials solutions and designs to enable new applications and address known risks
  • Development of data science tools and methods to quickly identify trends in reliability and technologies

Techno-economic analyses quantify the potential value and risk for new material solutions and designs and de-risking projects. Both the long term and the early stage de-risking projects will leverage our cutting edge data analytics and processing tools, along with our access to historical and streaming field performance data at the laboratories and from the PV Fleets Project.

For this call, proposals are intended to be 1 - 3 year efforts, starting in Oct. 2021 and ending by the end of Sept. 2024. The DuraMAT Consortium is currently divided into five core objective areas: Central Data Resource, Multi-Scale, Multi-Physics Modeling, Fielded Module Forensics, Disruptive Acceleration Science, and Materials Solutions. Proposals should leverage this structure and build on the resources established in FY17 – FY21. Descriptions of these core objectives are available at Proposals should directly address the research questions above and the challenges of making a 50 year module and system, having confidence that that module may indeed last 50 years, and knowing which components must be field repairable or replaceable in order to achieve the 50 year goal. During the 2020 Fall Workshop, DuraMAT participants and the Industry Advisory Board (IAB) identified five critical research outcomes and expected key results for DuraMAT 2.0 to accomplish that are the focus of this call (listed below). Proposals may leverage several core objectives and topics or focus in a single area.

  1. Evolve the DuraMAT DataHub into the Central Data Resource for PV
    1.  DataHub contains data from all DuraMAT projects, is scalable, and contains indexable data sets (doi, good metadata, license for use, FAIR)
    2. DuraMAT develops publicly available, open source data tools that directly address stakeholder needs
    3. DuraMAT conducts and disseminates quantitative analyses on topics such as: module reliability, sustainability, and economics
  2. Create a Multi-Scale, Multi-Physics Model

    3. Demonstration of detection of an unanticipated material or module weakness(es) using a test derived from outdoor field-use conditions
    4. Develop an accelerated testing method to study the initiation of wear out and key material degradation modes for wear out
    5. Validate an accelerated test method not yet adopted in the PV industry and benchmark relative to popular test methods
  4. Develop Fielded Module Forensics
    1. Pioneer new non-destructive/ field compatible methods to evaluate the failure modes and mechanisms associated with long-term wear out
    2. Development of materials forensics capabilities to de-risk high energy yield module designs and materials, including bifacial modules and glass/glass packaging
    3. Validate accelerated test protocols against field failures using a combination of structural, chemical, and mechanical characterization

  5. Develop Module Material Solutions
    1. De-risk innovative materials using the DuraMAT DataHub, multiscale modeling, accelerated and field testing, and/or materials forensics
    2. Enable emerging architectures such as flexible PV
    3. Development of sustainable materials solutions include repairs, component replacement, remanufacture, reuse, and design for recycling

In addition to the core objective areas the DuraMAT IAB identified a list of priority research areas for DuraMAT 2.0. The highest ranked priorities are listed below. PIs are encouraged to consider these topics when developing their proposals:

  • Reliability of new cell technologies
  • Predictive tools for long term degradation studies
  • Characterization tools for modules in the field
  • Highly accelerated lifetime testing development
  • De-risking emerging packaging designs and materials
  • Packaging or interconnect material substitution
  • Reliability of high power density modules
  • Case studies on fielded module degradation
  • Circularity and sustainability of modules
  • Module level power electronics

Additional topics (below) are also in scope but ranked as a lower priority by the DuraMAT IAB will also be considered.

  • Module Material data library
  • Climate specific reliability risk assessment and testing
  • Development and reliability of materials for module repairs
  • Thin film (non-silicon) module reliability
  • AR and/or AS coatings
  • Field studies at the Labs
  • Development of new packaging materials
  • Module mounting

We note that proposals focused on system performance, balance of system, or connectors are not of interest for this solicitation because they are covered under the SETO FY22 Lab Call. Successful proposals will be expected to have a mid- to long-term impact on addressing the DuraMAT goals by answering the DuraMAT questions, leveraging the results and capabilities of DuraMAT to date, and creating effective links between core objectives at the national laboratories. Proposals must have a well-defined work plan with clear yearly milestones and deliverables that support the DuraMAT Key Results listed in this solicitation. Proposals are encouraged to include industry participation and should address problems or
challenges identified as longer-term research needs by the PV industry.

The DuraMAT Consortium supports research opportunities in PV modules, focusing on packaging, interconnect, module materials, and module design. Cell research at the sub-module level (e.g. absorber or contacts) is excluded. Studies of high efficiency cell degradation as a function of module packaging and design may be submitted if they are clearly differentiated from other funded programs in the SETO portfolio. For example, research may include innovative accelerated testing, novel packaging materials and design, simulations or modeling that predict the durability and degradation mechanisms of new materials or designs, new data analytics that connect accelerated testing to field performance, data and risk-based technology evaluation tools, and more.

All project proposals are required to include a plan to submit FAIR compliant data with the DuraMAT DataHub. All proposals including the development of software tools must include open sourcedevelopment and release with full documentation and an example or demonstration data set for use. Modeling proposals relying on proprietary or commercial software packages must commit to sharing methods, input data, boundary conditions, output data, etc. so their work can be replicated using alternative software packages to the extent permitted by license conditions.


Proposals must have a National Lab PI from a DuraMAT core partner lab (NREL, Sandia, or LBNL) or core participant lab (SLAC) and are encouraged to consider partnerships with DuraMAT core participant Universities (Stanford University (SU), and Arizona State University (ASU)). Proposals may include team members from industry, national labs, academia, etc. as subcontracts, but at least 70% of the funding must stay within the DOE national laboratories. More information on working with DuraMAT can be found at . Cost Share is encouraged, but not required for this proposal call.
