Perovskite Material Photovoltaic Device and Method for Assembly

A method for manufacturing an electronic device comprising:

• depositing a first electrode layer onto a first substrate;
• depositing one or more first interfacial layers onto the first electrode layer;
• depositing a first photoactive layer comprising a first perovskite material or a first perovskite precursor material onto the one or more first interfacial layers;
• depositing a second electrode layer onto a second substrate;
• depositing one or more second interfacial layers onto the second electrode layer;
• depositing a second photoactive layer comprising a second perovskite material or a second perovskite precursor material onto the one or more second interfacial layers;
• orienting the second substrate such that the second photoactive layer is in contact with the first photoactive layer;
• applying a sufficient pressure to the second substrate to fuse the second photoactive layer with the first photoactive layer.
