EPFL’s Photovoltaics and Thin-Film Electronics Laboratory and CSEM have developed a triple-junction solar cell achieving a record efficiency of 30.02%, surpassing the previous record of 27.1%. The cell consists of a silicon bottom layer and two perovskite layers.

Innovations include a specialized molecule for crystal growth, a new fabrication process for light absorption, and nanoparticles to enhance light reflection. These developments could make high-efficiency solar cells more affordable and viable for both residential and space applications. The team plans to explore manufacturing scalability and product integration.
