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. The results clarify the underlying causes for reduced device performance, despite high local charge mobility, offering critical insights for designing improved solar cells.
