Abstract
A method of forming a photovoltaic device comprising a perovskite photovoltaic cell, particularly a method of forming a perovskite solar cell (PSC), is disclosed having a hole transport layer comprising an additive that may result in one or more of reduced formation of crystalline domains in the hole transport layer; reduced size of pinholes in the hole transport layer; improved dopant homogeneity and increased hydrophobicity of the hole transport layer. Also disclosed are PSCs so formed, showing one or more improved properties.
