| Popis: | In present investigation, co-precipitation as a simple, low temperature synthesis and low cost route was used to prepare nanocrystal perovskite La (Fe and Mn) O3 for solar cell application. The synthesized powders were characterized by XRD, SEM, PL, DRS, CV, EDS, and FTIR analysis. The photovoltaic behavior of prepared La (Fe and Mn) O3 perovskite as photo anode was also investigated, experimentally and theoretically. The best power conversion efficiency was experimentally obtained by LaFeO3 perovskite (0.07). Two different counter electrodes were applied: Pt electrode and an electrode prepared from a candle soot coated on the surface of FTO glass as a remarkable alternative material and process of noble metal electrode (Au or Ag) deposited by complicated vacuum technologies. In another stage, commercial electrolyte was used to enhance efficiency. These results indicate that there is a possibility to further increase the performance and efficiency of perovskite based cells. |
