An Epoxy-Based Micro-Structure Surface for Improving Anti-Reflection Efficiency of a Solar Cell Module

Abstract:

This paper proposes an epoxy-based anti-reflective micron structure layer for solar cell modules. A Solidworks software is used to design the micro-structure layers with different size and shapes (inverted pyramid and micro-lens). Then, An optical simulation software, Tracepro, is used to simulate the anti-reflection efficiency under the standard lighting source of AM1.5G. The difference between the flat layer and micro-structured layer has been analyzed to obtain the best micro-structure layer for solar cell modules. From the simulated results, the inverted pyramid textured layer that each pyramid’s width is 10μm and height is 5μm can improve the flux increment rate up to 13% compared with the flat layer at normal incidence. However, the best efficiency for micro-lens structure layer increases about 10% with radius of 25μm and height of 18.75μm and 25μm at 15o incidence. In addition, the thinner the Epoxy layer is, the better the anti-reflection efficiency is. Therefore, the proposed Epoxy-based micro-structure can improve the solar module for obtaining higher efficiency and best qualities.
