High-efficiency and low-cost silicon (Si)/organic hybrid solar cells have attracted significant attention as key devices to resolve global environmental problems, and also to enhance commercial usage. Herein, we report the correlation between the texture of the antireflection layer of hybrid solar cells composed of high-density textured Si and poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) and their photovoltaic performance. The ‘micro-desert' and ‘honeycomb' textured configurations on the Si surface provide an excellent antireflection capability for the incident wavelength range of 500-1000 nm, endowing the cells with a remarkably low reflectance value below 11%. The photovoltaic performance is strongly influenced by the morphology of such an antireflection layer. In comparison with the honeycomb configuration hybrid solar cells, the micro-desert textured cells exhibit a good photovoltaic performance and a high power conversion efficiency of 5.43%, due to the uniform adhesion of the PEDOT:PSS layer on the textured surface and the effective collection of the separated charge carriers at the electrodes after a post-annealing process at 200°C. These findings contribute to technical knowledge for the development of highly efficient hybrid solar cells with an antireflection layer.
