Perovskite solar cell
OverviewPerovskites for tandem applicationsAdvantagesMaterials usedProcessingToxicityPhysicsArchitectures
A perovskite cell combined with a bottom cell such as Si or copper indium gallium selenide (CIGS) as a tandem design can suppress individual cell bottlenecks and take advantage of their complementary characteristics to enhance efficiency. These types of cells have higher efficiency potential, and therefore have attracted attention from academic researchers. Using a four terminal configuration in which the two sub-cells are electrically isolated, Bailie et al. obtai
