Electron transport of chemically treated graphene quantum dots-based dye-sensitized solar cells

Fourth-generation solar cells: a review

“…The combination of the discussed solar cells may also lead to the formation of heterojunction solar cells that show enhanced photovoltaic properties or characteristics compared with their individual counterparts. A demonstration of such a 2D/3D bulk heterojunction solar cell that consists of a 2D/3D inorganic perovskite has been shown by Kang et al 212 Similarly, a heterojunction solar cell of 2D materials based PSCs and OSCs, 213 quantum dot-based PSCs, 214 graphene quantum dot-based DSSCs, 215 and organic sensitizers for DSSCs 216 have been reported in the literature.…”

Graphene quantum dots for biosensing and bioimaging

“…85,89 The electrochemical works span over capacitors, [133][134][135] hydrogen evolution reaction (HER), 136,137 fuel cells, 138,139 ORR 140,141 and photovoltaic cells. 142,143 The combination of photoluminescence and electrochemical aspects of GQDs helps in the development of electrochemiluminescence sensors 144,145 and photo detector devices. 146…”

The impact of a TiO2/r-GO composite material on the performance of electron transport electrodes of dye sensitized solar cells

“…Therefore, the use of TiO 2 in conjunction with diverse carbonbased materials, including carbon nanotubes, carbon nanorods, carbon quantum dots, and carbon nanobers, to augment the efficiency of DSSCs has garnered signicant interest from the global scientic community. [14][15][16] The integration of r-GO with TiO 2 has been recognized as a promising approach to enhance electron transport and electron lifespan, owing to the remarkable qualities exhibited by r-GO. 17 These properties include good thermal and electrical conductivity, a large specic surface area, and a membrane-like structure.…”
