Organic-inorganic hybrid perovskite solar cells have experienced explosive development in recent years, owing to their great potential for use in next-generation solar panels. They display ideal photophysical properties, as well as highly desirable ease of processing and low cost. However, unlike other types of solar cells, they exhibit relatively low absorption of red light, a flaw which results in a significant loss of solar conversion efficiency.
In this work, I will show how silver nanocubes have demonstrated the ability to improve the absorption of perovskite thin films in the red region of the electromagnetic spectrum via scattering and localized surface plasmon effects. The experimentally-observed improvement fits simulated outcomes nearly perfectly. This optimization of film absorption should allow for an increase in the light harvesting efficiency of perovskite solar cells and for the fabrication of thinner films, facilitating the collection of photocarriers and permitting the reduction of potentially toxic compounds used in the cell.
