摘要：

Flexible solar cells are widely researched for their potential usage in photovoltaics integrated into buildings, cars, unmanned arial vehicle and wearable electronics. The thin crystalline silicon solar cell (60-90 mu m) is prone to crack due to surface texture when it is under bending. Here we investigated the effect of pyramid size on optical reflectivity and mechanical properties of silicon wafers. We find that smaller and uniform pyramids are beneficial for obtaining efficient and flexible silicon solar cells.
