Energy Spotlight: Toward the Design of High-Efficiency Solar Cells

Kai Zhu, Samuel Stranks

Research output: Contribution to journalArticle


The quest to improve the efficiency and long-term stability of perovskite solar cells has led to the design of tandem solar cells. The Energy Spotlight in this issue highlights recent advances in designing perovskite/CIGS (copper indium gallium selenide) tandem solar cells. New strategies such as the formation of quadruple-cation-based wide-bandgap perovskites through controlled vacuum deposition assist in attaining greater thermal stability. The salient features of these advances in perovskite solar cells are presented below.
