Exploring the influence of Zn2SnO4/ZIF-8 nanocomposite photoelectrodes on boosting efficiency of dye sensitized solar cells

Facile Synthesis of a Multifunctional SnO2 Nanoparticles/Nanosheets Composite for Dye-Sensitized Solar Cells

“…Dye-sensitized solar cells (DSCs) have attracted tremendous interest over the past decade and have shown significant promise for practical photovoltaic applications owing to their low cost and effective photovoltaic performance. − Since the first study on mesoporous titania-based photoanode films was published in 1991, numerous studies on DSCs have been conducted. To date, efficiencies of more than 12% have been achieved by using a mesoporous film of sintered TiO 2 nanoparticles as the photoanode. , In addition to the frequently used TiO 2 , alternative semiconductors with broad band gaps, such as SnO 2 , , ZnO, , Nb 2 O 5 , , and Zn 2 SnO 4 , , are also being investigated. Among them, SnO 2 is one of the promising and reliable candidates for DSCs due to its wide band gap (3.62 eV) and high electron mobility (100–200 cm 2 V –1 s –1 ) compared to TiO 2 . − Such exceptional features make it favorable for electron transfer within the photoanode film, thereby improving the photoconversion efficiency of the DSCs.…”

Delafossite CuCoO2/ZnO derived from ZIF-8 heterojunctions as efficient photoelectrodes for dye-sensitized solar cells

“…Without the need to a stabilizing agent or activation procedures like heating, microwave irradiation, or ultrasound, it is feasible to efficiently synthesize ZIF-8. 27 Recently, ZIF-8 was thermally treated to create porous ZnO photocatalysts, which improved methylene blue degradation. 28 Such a method would be investigated further for hybrid synthesis and heteroatom doping.…”
