Effect of Ti1−xFexO2 photoanodes on the performance of dye-sensitized solar cells utilizing natural betalain pigments extracted from Beta vulgaris (BV)

“…To achieve better and high PCE, the design of photoanodes having optimum dye loading, better sunlight scattering, effective transportation of charge carriers, and reduced charge carrier recombination is the most crucial thing to look into. 5 In general, metal oxides are preferred for the photoanodes and mesoporous nanostructures of TiO 2 , ZnO, SnO 2 , Nb 2 O 5 , etc. , are widely investigated.…”
