Abstract
Perovskites, materials with main chemical formula ABX3 where A are cations of organic molecules and/or metalic cations (e.g. Cs+), B are transition metals with 2+ oxidation state, and X are halides, attract great interest for the application in photovoltaic devices due to low synthesis costs and high power conversion energy (PCE), exceeding 25 percent. Although perovskites have been widel…
