Influence of Nanostructures in Perovskite Solar Cells

Inorganic–organic hybrid perovskite solar cells, a low-cost viable substitute to conventional silicon technology, have seen an unparalleled efficiency improvement within a span of few years due to their unique tunable properties and ease of fabrication methodology. These hybrid structures are greatly influenced by nanomaterials/nanostructures in enhancing their properties. Nanostructures implemented into sensitizing, hole transporting and electron selective layers in these devices, aid to increasing surface area-to-volume ratio, facilitate charge accumulation, and transport through interfaces. Nanocarbons are seen as potential alternatives to organic hole conductors, boasting inexpensive earth-abundant components, and good stability. Perovskite photovoltaic devices have prospects of becoming an important source of clean energy devices, or even powering portable devices.
