2-Dimensional Perovskite Photovoltaics Produced with Organic Additives

Perovskites are a type of crystalline material that offer great benefits when it comes to sustainable solar power. They are comparably efficient and significantly lower cost than silicon, which is what is overwhelmingly used for solar panels nowadays. While perovskites are very much compelling because of what they offer, they have their downsides such as not being environmentally stable. From past experience it is believed that by adding organic additives that tune the dimensionality of the crystal structure, the perovskite can be engineered as more robust and reliable for longer operational lifetimes. During this study it is planned on adding organic additives to the perovskite ink then do photoluminescence (PL) spectroscopy, fracture energy, and environmental stability measurements to further understand the electronic structures, mechanical stabilities, and long-term stabilities of the samples.
