The researchers described the solar cell in “High-Efficiency Silicon Inverted Pyramid-Based Passivated Emitter and Rear Cells,” which was recently published in Nanoscale Research Letters.

Researchers at Stanford University have created a glass pyramid optical concentrator that concentrates light on solar cells, regardless of the light incidence angle. “It’s a completely passive ...
