Abstract
Strong characterization methods are needed to fully comprehend the chemistry and composition of perovskite solar cells. Understanding the interaction between layers inside a cell and how they react with the environment is important to achieve optimum manufacturing processes, and improve efficiency of perovskite solar cells. Here, we probe a hybrid organic-inorganic perovskite cell structure formed by a fluorine-doped tin oxide (FTO), cassiterite (SnO2), mixed halide perovskite, Spiro-OMeTAD and silver layers. We have demonstrated a power conversion efficiency (PCE) greater than 19% and aVoc of more than 1.1 V for a wide-band gap (1.6 eV) perovskite solar cell.
