Design of Microlens Focused V-groove Textured Silicon Solar Cell with Different Aspect Ratio Using ZEMAX®

Abstract

Improving the utilization ratio of sunlight is a key factor for the development of solar cell.  In this work a V- groove model micromachined solar cell is designed and studies can be carried out for improving the efficiency of the microlenses focused solar cells with different aspect ratio.  The simulation result shows the maximum of 40% increase in photonic absorption is observed in the V-groove silicon solar cell with 2 µm pitch and 1.5 µm height texture is better for light trapping structure.
