Post-black etching on emitter to improve performance of multi-scale texture silicon solar cells
Source abstract
Abstract
A simple, low-cost, post-black etching process atop the random pyramidal emitter has been proposed and investigated. The multi-scale texture is achieved by combining nanoporous layer formed by the post-black etching with micron-scale pyramid texture. Compared to the pre-black etched Si solar cells, our experiments clearly show the advantage of post-black etched texturing: it enables high blue response and improved conversion efficiency. As a result, the enhancement of 7.1 mA/cm2 on the short-circuit current density and improvement of 31 % in the conversion efficiency have been reached.
