Abstract

The efficiency of pyramid textured silicon solar cell with ZnO nanotip array was investigated. ZnO seed layer was first prepared on the top side of solar cell by radio frequency sputtering. Zinc nitrate and ammonium were used as precursors for the growth of ZnO nanotip array on ZnO seed layer by aqueous solution deposition at 70 °C. The efficiency of solar cell with ZnO nanotip array increases with the ZnO nanotip length, and the efficiency can be enhanced from 11.74% to 14.38%.
