In Depth

Key Findings

The U.S. Department of Energy (DOE) has updated stakeholders on its Fiscal Year 2020 Perovskite Funding Program, underscoring its sustained strategic investment to accelerate the commercialization of perovskite solar cell technology. This program specifically targets improvements in device efficiency and stability, tackles critical challenges in module manufacturing, and establishes robust testing protocols for long-term field performance validation. With $20 million awarded in 2020 and an additional $40 million distributed across 22 promising projects in 2021, the DOE demonstrates a strong commitment to advancing this innovative solar technology.

Technical Details

Funded projects span a broad spectrum of perovskite solar cell challenges. Research focuses on novel material compositions and device architectures to overcome the inherent instability of perovskite materials, alongside optimizing scalable manufacturing techniques such as roll-to-roll printing and spray coating for large-area production. Emphasis is also placed on accelerated degradation testing and real-world outdoor demonstrations to evaluate long-term performance. These efforts are crucial for perovskite solar cells to achieve reliability and cost-effectiveness comparable to or exceeding conventional silicon solar cells.

Background & Context

Perovskite solar cells are emerging as a leading next-generation photovoltaic technology due to their high theoretical efficiency, low-cost material inputs, and adaptability to flexible substrates. The DOE positions perovskite technology as a key strategic area to accelerate the transition to a clean energy economy and enhance U.S. energy independence. This funding program is designed to bridge the critical gap between laboratory breakthroughs and commercial product realization, thereby contributing to technological innovation and competitive strength within the U.S. solar industry.

Strategic Significance & Outlook

The DOE plans to explore additional funding opportunities to further support perovskite solar cell R&D and commercialization. The ultimate goal is for perovskite technology to contribute significantly to large-scale power generation, aiding the ambitious target of achieving 100% clean electricity across the U.S. grid by 2035. Anticipated applications extend across diverse market segments, including Building-Integrated Photovoltaics (BIPV) and portable devices, with the introduction of these technologies expected to reduce energy costs and create new jobs.
