As perovskite solar cell efficiencies have risen rapidly, practical constraints have made durability a critical concern. Whereas much attention has been paid to the development of the perovskite absorber layer, the charge transport layers can also be engineered to better the performance and stability of the device. This work uses the molecular modifier bromopropyltrimethoxysilane (BPTMS) to alter the interface between indium tin oxide (ITO, a common thin film solar cell transparent electrode) and methylammonium lead iodide (MAPbI3, a common perovskite absorber) to improve the morphology and stability of the perovskite absorber film. The substrate, molecular modifier, and perovskite film were characterized via contact angle measurements, spectroscopic ellipsometry, and scanning electron microscopy. It was determined that the absorber film morphology and stability of the stack are sensitive to both the underlying substrate and the BPTMS.
