half-tandem cells, which consist of one cell comprised of two active layers, stacked on top of each other without an intermediate layer
team used methylammonium lead iodide (MAPbI3), a perovskite material, and molybdenum ditelluride (MoTe2) to form the two layers
th the latter material driving an increase in conversion efficiency from 12.13%, before its addition, to 27.01%, after its inclusion
changed the nanostructure of the components to resemble a V-shape, to “enhance light absorption through light trapping,” further increasing the power conversion efficiency to 27.63%
2.35 times efficiency enhancement for the nanostructured V-shaped half-tandem solar cell with MAPbI3 and MoTe2 as absorbent layers
