MPPT 20.13%! Photon Crystal Energy breaks stable-state PCE record on perovskite mini module, stepping onto a new stage of industrialization.

Certified by the National PV Industry Measurement and Testing Center, Photon Crystal Energy has recently achieved maximum power point tracking (MPPT) steady-state efficiency of 20.13% on a Perovskite mini module, with aperture area of 815.9 cm2. This is the highest steady-state efficiency record for such 30 cm x 30 cm size modules. Perovskite modules boast advantages such as higher power conversion efficiency (PCE) on weak sunlight condition and a lower temperature-attenuation coefficient. With a steady-state efficiency above 20%, perovskite modules of similar area can now rival the actual power generation capability of mainstream monocrystalline silicon TOPCon modules with 22% PCE under the equivalent working conditions, surpassing previous generations of other thin-film PV technologies. Therefore, the breakthrough of over 20% steady-state efficiency on perovskite mini modules represents a significant milestone, propelling perovskite PV technology onto a new stage of industrialization.

Based on its proprietary ink engineering technology, stability enhancement technology, and large-scale perovskite thin film printing process, Photon Crystal has verified the scalability of ink engineering and all-printing process on 30 cm x 30 cm mini modules in March 2023. After another year of research and innovation, the team iteratively upgraded the ink formula, enhancing the film quality of perovskite while keeping process parameters consistent. They also fine-tuned the spectral absorption range, thereby improving overall photoelectric parameters. Meanwhile, the introduction of unique additives stabilized the crystal structure, significantly improved the steady-state output capability of perovskite modules at their maximum power point.

The milestone of achieving over 20% steady-state efficiency on mini module establishes a robust technical foundation for Photon Crystal Energy’s pilot line production. The company is actively building a 100MW pilot line in Nanhai District, Foshan City, aiming for operational commencement in the first half of 2024. Anticipating a 20% efficiency milestone on 1.2 m x 0.6 m commercial-size modules by the end of 2024, Photon Crystal Energy envisions the initiation of a GW-level perovskite mass production factory in 2025.

Photon Crytal, rooted in the Greater Bay Area with a global perspective, is ready to collaborate with partners across all sectors of the industry, accelerating the industrialization of perovskite PV technology. By producing high-quality and low-cost PV products, Photon Crystal will make solar energy available for everyone and significantly contribute to China's grand goals of carbon neutrality and carbon peaking, as well as to the green energy transition across the world.
