In 2022, publicly traded footwear producer and solar technology maker Golden Solar, based in China, signed an agreement with two partners to pursue commercial production of perovskite tandem solar cells with 'more than 28%' conversion efficiency. Now, Golden Solar New Energy Technology Holdings Limited has announced the launch of its perovskite/hybrid BC Tandem Solar Cells.
Golden Solar stated that it will apply 'the world's most advanced battery technology to C-end products, gradually develop a series of ultra-high-efficiency C-end products, and open up a broader space for growth'. Recently, the first perovskite/hybrid BC four-terminal tandem solar cell was launched, claimed to have a conversion efficiency of 33.94%.
This solar cell was jointly developed by the National Engineering Research Center for High-efficiency Solar Cell Equipment and Technology (Jinshi, Fujian), Golden Solar and Huaqiao University. Tested by the National Photovoltaic Industry Measurement and Calculation Center, the conversion efficiency of the top perovskite cell of this tandem cells is 21.34%, and the conversion efficiency of the bottom hybrid BC cell is 12.6%.
After stacking, the conversion efficiency reportedly reaches 33.94%. Reports suggest that Golden Solar is the inventor of crystalline silicon fully flexible components and has successfully completed the vertical integration of the industry from silicon wafers to batteries to components.
Based on the company's current mature and stable BC battery technology and flexible component lamination and packaging technology, Golden Solar launched "flexible awning for RVs", its first product for the C-end market in June this year, and has reportedly begun mass production and delivery.
