Researchers investigated the internal properties of low-cost materials used in perovskite solar cells, which are attracting attention for their high efficiency, using electron spin resonance (ESR) to analyze these materials at a microscopic level.
Researchers investigated the internal properties of low-cost materials used in perovskite solar cells, which are attracting attention for their high efficiency, using electron spin resonance to analyze these materials at a microscopic level. The results clarify the underlying causes for reduced device performance, despite high local charge mobility, offering critical insights for designing improved solar cells.
The researchers at University of Tsukuba employed ESR to investigate the underlying mechanisms for the performance limitations of perovskite solar cells incorporating HND-2NOMe, focusing on the material's internal properties at a microscopic scale. They discovered that in the absence of illumination, holes migrate from perovskite to HND-2NOMe, forming an energetic barrier at the perovskite/HND-2NOMe interface. This barrier impedes hole flow, leading to performance limitations.
