| Abstract |
| Due to high verified efficiency in recent years, the regular architecture (n-i-p) of perovskite solar cells (PSCs) has piqued attention in the renewable energy area. Delafossites are mixed metals oxides semiconductors of the P-type. Thus, it used as hole transport layer (HTL) in optoelectronic devices. In the current research, we investigate hydrothermal synthesis of delafossite; CuFeO2 and its used as HTL in (CH3NH3PbI3) perovskite solar cells. Simple FTO/C-TiO2/m-TiO2/CH3NH3PbI3/HTL/C solar cells structure was fabricated, via two-step deposition technique, with different HTLs. The structure and microstructure of the raw materials are investigated using XRD. The photovoltaic performance of the fabricated devices was investigated using the IV measurements. The investigation showed that, the photovoltaic parameters, including short-circuit-current (Jsc), open-circuit-voltage (Voc) and Fill factor (F.F) for the fabricated devices, were found to be strongly improved when using the mesoporous TiO2 and different HTL. Overall, we believe that this research demonstrates the utility of inorganic HTMs for the commercial distribution of long-term stable and low-cost PSCs. |
