Tin-Based Perovskites Nontoxic Alternative for Solar Energy Production

Sustainability icon, disabled. A green leaf.

The research focuses on improving the sustainability of perovskite films by replacing toxic lead (Pb) with tin (Sn), aiming to create efficient, transparent photovoltaic window materials. By using a fully inorganic precursor, CsSnBr3 (cesium tin bromide), the goal is to develop a more stable crystalline structure. The research aims to improve ink quality by identifying the issues affecting solubility. The goal is to create a stable, sustainable, and fully dissolved ink that can form a thin, uniform layer on glass slides. Once the ink is achieved, the focus will shift to maximizing the efficiency of the perovskite without significantly compromising transparency.
