TandemPV has announced a 30.4% efficient perovskite/silicon demonstration module, weeks after the company reported crossing 30% efficiency.
The 100 cm² mini-module, featuring the company’s proprietary 4-terminal perovskite glass layer atop a high-efficiency Maxeon IBC silicon solar cell, is now in third-party certification.
Company CEO, Scott Wharton, says the breakthrough paves the way for full-size modules that hit 28% efficiency later this year, aimed at the utility-scale market.
