Mme Mirella Al-Katrib will present her thesis "Perovskite Solar Cells Developed Using Electrodeposition".
Abstract : In the last decade, halide perovskites have drawn substantial interest in the fields of photovoltaic. However, the most used method to deposit perovskite active layer is spin coating, which presents many constraints such as limited surface coverage, high production price, non-homogeneity, undefined perovskite crystallinity, poor stability and must be elaborated under inert atmosphere. Alternative methods must be explored, such as electrodeposition since it solves the as-mentioned disadvantages. In this work, we were able to develop different types of perovskites using electrodeposition, understand the impact of the different deposition parameters on their structure, and improve their stability comparing to the spin-coated ones. An innovative approach was reached by electrodepositing different mixed perovskites MAPbI3-xClx and MA1-yFAyPbI3-xClx, and elaborating a p-i-n solar device using electrodeposited MAPbI3. However, an optimized solar cell architecture must be found, corresponding to the electrodeposited perovskite, to further enhance the efficiency.
