| Abstract | The excellent optical and electrical properties of silicon nanocrystals had attracted interest in the application of silicon-based solar cells. Optical coupling of nano silicon on the surface of solar cells was a valuable technology conducive to large-scale use, and the controlled optical properties of silicon nanofilms could better enhance the light absorption of solar cells. In this paper, we demonstrated that the efficiency of monocrystalline silicon solar cells could be effectively improved by spin-coating a nano silicon solution on the solar cell surface. The maximum value of absolute efficiency improvement was 0.23%. Moreover, this gain was shown to come from the additional absorption of light by the silicon nanofilms. The surface optical properties of the silicon nanofilms applied to the solar cell surface and the electrical properties of the solar cell were calculated by transmission matrix method (TMM) calculations and simulations with the Silvaco TCAD. It provided accurate predictions and explanations for the preparation of silicon nanofilms. |
