Scientists in China took a closer look at the role of defects in limiting the performance of perovskite solar cells, demonstrating a screening effect that could be tuned to make material defects "invisible" to charge carriers, greatly improving cell performance. Using this approach they demonstrate a 22% efficient inverted perovskite solar cell, and theorize several new pathways to even higher performance.While scientists have quickly pushed the efficiency of perovskite solar cells to levels that rival or even surpass some of today's commercial technologies, gaining a full understanding of all ...Den vollständigen Artikel lesen ...
