Which choice best describes data from the graph that support Taylor and colleagues’ conclusion? Power Conversion Efficiency of Lowest and Highest Performing Spin-coated and Spray-coated Electron Transport Layers • Lowest performing spray coating: 15.48% • Lowest performing spin coating: 11.70% • Highest performing spray coating: 17.26% • Highest performing spin coating: 13.56% Perovskite solar cells convert light into electricity more efficiently than earlier kinds of solar cells, and manufacturing advances have recently made them commercially attractive. One limitation of the ce lls, however, has to do with their electron transport layer (ETL), through which absorbed electrons must pass. Often the ETL is applied through a process called spin coating, but such ETLs are fairly inefficient at convert ing input power to output power. André Taylor and colleagues tested a novel spray coating method for applying the ETL. The team pro duced ETLs of various thicknesses and concluded that spray coating holds promise for improving the power conversion efficiency of ETLs in pero vskite solar cel ls.
