Control Surface Templates for Solution-Processed Hybrid PEDOT: PSS - Silicon Solar Cell

Abstract

In this work, we use the metal-assisted chemical etching (MACE) to produce our multi-scale surface textures, namely "Hierarchical structure", which is combined with micropyramid and nanowires. The templates are modulated through controlling the morphology of silver cluster on the randomly distributed micro-pyramidal surface with rapid thermal annealing (RTA) and the ratio of hydrogen fluoride (HF) and hydrogen peroxide (H2O2) during metal-assisted chemical etching. The power conversion efficiency (PCE) of new multi-structure on a hybrid solar cell can achieve 14.07 % by reducing reflectance to 3.61 % and enhancing Jsc to 33.43 mA/cm(2) with a 1x1 cm(2) active area.
