Abstract
The solar photovoltaic was well recognized as one of the major constituent parts in future green energy system to achieving carbon neutrality. Among various technological routes to improve photoelectric conversion efficiency, rational surface texturization on monocrystalline silicon is one of the most crucial and fundamental processing steps, so as to well control the micro/nano surface structure and obtain lower light reflectivity. Chemical wet etching was the current mainstream technology in photovoltaic industry, yet there is an urgent need to update green, efficient, customized texturization additives to meet the industrial demand. This minireview summarizes the history, key breakthrough and recent advance in texturization additives based on organic and polymer molecules as crucial chemicals, and provides perspective to development directions of future texturization additives.
