A mixed-cation lead iodide MA1−xEAxPbI3 absorber for perovskite solar cells

A mixed-cation lead iodide MA1−xEAxPbI3 absorber for perovskite solar cells
The mixed-cation lead halide perovskites have emerged as a new class of promising light harvesting materials for solar cells. The formamidinium (FA), methylammonium (MA) and Cs cations are widely studied in the field of mixed-cation perovskites. Here, we have investigated ethylammonium (EA) as an alternative cation to fabricate a mixed-cation perovskite of MA1- x EA x PbI3. We have characterized the materials using the X-ray diffraction (XRD), scanning electron microscope (SEM), and UV–vis spectrum. Our results have confirmed the successful incorporation of EA cations into MAPbI3. Interestingly, the optimal amount of EA to achieve the best performance is quite low. This is different from the FA–MA mixed-cation perovskites although EA and FA have similar radii. In short, the EA–MA mixed-cation perovskite has some material and device properties highly distinguishable from the FA–MA one.
