Our team has developed a high-efficiency semi-transparent perovskite solar cell technology that can be integrated with existing Si-based solar cells to enhance the power conversion efficiency per unit area and has achieved significant success in developing a world record with a power conversion efficiency of over 20%. We aim to transfer more technologies to midstream and downstream manufacturers, enhancing Taiwan＇s competitiveness in the international solar cell market.

Perovskite solar cells achieve a conversion efficiency of 21.68%. Utilizing tandem technology, the conversion efficiency of HJT solar cells is increased to ~29%. The efficiency of 2-inch semi-transparent modules reaches 16.2%, with T90 values of 1600 hours under 85°C/85%RH test and 1,000 hours under continuous light exposure. Demonstrating 8×8 cm2 large-area modules fabricated using a full process under ambient condition, with a conversion efficiency of 10%.

Our team offers strategies for businesses entering the market: (1) Secure access to formulation materials and low-cost, solution-process technologies through technology licensing or by selling materials to upstream suppliers for mass production. (2) Focus on semi-transparent PSCs to help optoelectronic companies establish tailored production lines. (3) Establish a material design platform to support upstream and optoelectronic companies in material development and process optimization.
