Ray tracing analysis of the inverted pyramid texturing geometry for high efficiency silicon solar cells
A.W. Smith,Ajeet Rohatgi +1 more
TL;DR: In this article, a quantitative analysis of the internal and external light trapping characteristics of the inverted pyramid geometry is presented for the first time, showing that the inverted pyramids geometry is able to confine the light better than the slats or upright pyramid designs, but possesses slightly poorer light trapping efficiency compared to a Lambertian front surface design.
