Stable Perovskite Solar Cells Using Reduced Graphene Oxide Additive
Abstract
Reduced graphene oxide (RGO) has been commonly used as an additive in the optoelectronic devices
account to its unique properties. Here, we added 6% of RGO into mesoporous titanium dioxide (mpTiO2) to improve the performance of perovskite solar cells (PSCs). The RGO addition resulting in
enhanced the crystal structure and optical absorbance of the corresponding perovskite film. The
charge transport also was improved and recombination processes reduced due to better interfacial
perovskite/mp-TiO2 contact. With this treatment, the optimized PSC achieved a power conversion
efficiency of 14%. Most important, the humid long-term stability was improved after using RGO
additive. PSCs with RGO maintained about 90% of their original performance after storage in ambient
air with a relative humidity of 30-50%.
