Fabrication of inverted pyramid structure for high-efficiency silicon solar cells using metal assisted chemical etching method with CuSO4 etchant

Inverted pyramid texture is used to improve the performance of single crystalline silicon (sc-Si) solar cell due to its excellent light-trapping properties. In this paper, inverted pyramid structures are fabricated on large area sc-Si wafers by metal assisted chemical etching method using CuSO4 inst...
