This study presents the ways to develop high-efficiency next-generation solar cells. For this purpose, we optimize both working electrode and counter electrode to enhance the device efficiency and decrease its production cost. As a result, TiO2 based nanofibers (TiO2@SnO2, N-doped SnO2/TiO2, ZrO2/TiO2, N&GO@ SnO2/TiO2, GO@SnO2/TiO2, GO@ZrO2/TiO2) were successfully synthesized through electrospinning method and their application as a low-cost and efficient working electrode of dye-sensitized solar cells (DSCs). Pt-based nanoalloys (PtSn, PtRu, PtPd, PtAu, PtFe, PtCo, PtCu, PtNi, PtZr, PtPd) and Pt-free nanoalloys (NiCo PdCo) were successfully synthesized through dry plasma reduction and their application to low-cost and efficient counter electrodes of DSCs. The obtained result provides the basis for cost-effective and green technology for developing efficient next-generation solar cells required for commercial applications. |
