MPPT 20.13%: Photon Crystal Energy Sets a Steady-State Efficiency Record for Large-Area Perovskite Modules, Marking a New Step Toward Industrialization

Recently, as certified by the National Photovoltaic Industry Metrology and Testing Center, the 815.9-square-centimeter large-area perovskite module developed by Photon Crystal Energy achieved a steady-state efficiency (MPPT) of 20.13%, setting the highest steady-state efficiency record for 30 cm x 30 cm modules. Perovskite modules offer advantages such as strong low-light power generation and a low temperature coefficient. Under the same working area and conditions, perovskite modules with steady-state efficiency above 20% can already match the actual power generation capability of 22%-efficient crystalline silicon TOPCon modules currently on the market, surpassing previous generations of other thin-film PV technologies. Therefore, a steady-state efficiency breakthrough above 20% for large-area perovskite modules is an important industry milestone, marking a new stage in perovskite PV industrialization.

Based on its proprietary ink formulation technology, stability enhancement technology, and fully printed process, Photon Crystal Energy verified the scale-up feasibility of its ink formulation technology and fully printed process on 30 cm x 30 cm modules in March 2023. After nearly a year of R&D innovation, the team iterated and upgraded the ink formula, improving the perovskite film quality without changing process parameters. It also optimized the spectral absorption range, thereby improving optoelectronic parameters. In addition, the introduction of unique additives stabilized the crystal structure and greatly improved the module's ability to sustain stable output at the maximum power point.

Photon Crystal Energy's milestone of exceeding 20% steady-state efficiency on large-area modules lays a solid technical foundation for pilot-line production. The company is building a 100 MW pilot line in Nanhai District, Foshan, where construction is progressing in an orderly manner. The line is expected to be completed and put into operation in the first half of 2024. The company aims to reach 20% efficiency on 1.2 m x 0.6 m commercial-size modules by the end of 2024 and begin construction of a GW-scale perovskite mass-production plant in 2025.

Rooted in the Greater Bay Area and looking to the world, Photon Crystal Energy is willing to work side by side with partners across the industry to accelerate perovskite PV industrialization. Through high-quality and affordable PV products, the company aims to make solar energy available everywhere and contribute meaningfully to China's carbon neutrality and carbon peaking goals, as well as the global green energy transition.
