That is why perovskite solar cells are getting attention as next generation solar cells. Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009 to 25.5% in 2020 in single-junction architectures, and, in silicon-based tandem cells, to 29.1%, exceeding the maximum efficiency achieved in single-junction silicon solar cells. • The DJ 2D perovskite layer could form cascade HOMO levels between 3D perovskite and hole transport layer, favorable for hole transfer and extraction. One of the main challenges for the scientific community and the PV industry to bring perovskite solar cells (PSCs) to commercial production is the need to improve moisture stability. The group went on to fabricate full solar cells from these films, the best performing of these had an initial efficiency of 23.1%. Adv. Further analysis on the stability of the perovskite solar cells will be discussed. With the bandgap tu … A piperidinium salt stabilizes efficient metal-halide perovskite solar cells Science.
