TL;DR: It is shown that using cesium ions along with formamidinium cations in lead bromide–iodide cells improved thermal and photostability and lead to high efficiency in single and tandem cells.
Journal ArticleDOI
TCO and light trapping in silicon thin film solar cells
TL;DR: In this article, the effect of aluminum-doped zinc oxide (ZnO:Al) front contact and the role of the back reflector on the performance of thin-film silicon solar cells is investigated.
Journal ArticleDOI

TL;DR: A monolithic perovskite/silicon tandem with a certified power conversion efficiency of 29.15% is reported, made possible by a self-assembled, methyl-substituted carbazole monolayer as the hole-selective layer in the perovSKite cell.
Journal ArticleDOI
