Kunshan GCL Optoelectronic Materials

Kunshan GCL Optoelectronic Materials, established in 2019 and previously known as Xiexin Photoelectric, is a material company focused on the research, development, and manufacturing of perovskite solar modules. The firm is a subsidiary of the GCL Group and is headquartered in Kunshan, China. The core research team, led by founder Dr. Fan Bin, began its work on perovskite photovoltaic technology in 2013, accumulating over a decade of experience. Dr. Fan holds bachelor's and master's degrees in chemistry from Tsinghua University and a doctorate from EPFL in Switzerland. The company's journey began with its predecessor, Xiamen Weihua, in 2010, which later shifted focus to perovskite commercialization in 2013. After being acquired by GCL Group, it relocated to Suzhou and completed a 10MW R&D line between 2016 and 2017.

GCL Optoelectronic Materials operates in the renewable energy market, specifically targeting the solar power sector. Its business model revolves around the manufacturing and sale of perovskite solar panels. Revenue is generated by providing these advanced solar modules to the global market. The company is positioning itself to lead the commercialization of this next-generation photovoltaic technology. A key part of its strategy involves a gigawatt-scale production facility and scenario-based demonstrations to validate its products in diverse environments, including building-integrated photovoltaics (BIPV) and even space applications. To accelerate development, the company has established an AI-driven high-throughput research center in partnership with Suzhou Laboratory and Soochow University.

The company's primary offering is large-format perovskite photovoltaic modules, available in both single-junction and tandem (perovskite-on-silicon) configurations. These modules are notable for their high conversion efficiency and large size. As of mid-2025, the company has reported a certified efficiency of 29.51% for a 2,048 cm² perovskite-silicon tandem module. Its 1m x 2m single-junction module achieved a record 19.04% efficiency and has passed TÜV Rheinland's IEC 61215 and IEC 61730 safety and reliability certifications. Compared to traditional crystalline silicon, perovskite technology offers benefits such as lower manufacturing costs, reduced energy consumption during production, and a lightweight, flexible form factor. The firm plans to commence mass production from its first gigawatt-scale production line by the end of 2025, aiming to launch 2.88 m² tandem modules with 27% conversion efficiency.
