Perovskite solar cells offer an alternative approach to photovoltaic solar power generation versus traditional silicon solar cells, by rivaling their efficiency at potentially less than half the cost. Perovskite’s name comes from the crystal structure that encompasses the active layer (Methylammonium Lead Iodide – CH₃NH₃PbI₃), the region that absorbs photons and generates electrical energy by creating electron hole pairs. The presence of the organic cation (methylammonium) causes degradation of the active layer under humidity, UV light, and high temperature, which lowers the effectiveness of the cells. This project investigates low-cost routes and materials for …
