Eosin‐G and ethyl eosin dye sensitized CdS nanowires towards dye sensitized solar cells applications

“…[2] Among various possible nanostructures used for photoanode, one dimensional (1-D) nanostructures (such as nanowires [NWs], nanorods [NRs], nanotubes [NTs], or nanofibers [NFs]) have been proven to offer enhanced photo conversion efficiency by providing easy electron transition because of smaller electron transport resistance (R ct ) and longer electron (L e ) diffusion length in photoanode [3,4] and hence, NWs have been used in DSSCs since the early 21st century. [5,6] Researchers have predominantly worked on metal oxides like TiO 2 , [7,8] ZnO, [9] WO 3 , [10][11][12] Nb 2 O 5 , [13][14][15][16] and SnO 2 [17][18][19][20] for the application of NWs in DSSCs. In recent years, much interest has been shown on ternary metal oxides like BaSnO 3 [21][22][23] and ZnSnO 4 [24,25] based on their relevant valence orbital and electronic properties.…”

Bulk heterojunction solar cell using Ru dye attached PCBM

“…Despite the diverse research avenues within this field, the direct application of efficient Ru dyes in the primary absorption layer, particularly within heterojunction solar cells, has remained limited [7][8][9][10]. Ru dyes are extensively utilized as photosensitizers in DSSCs, where they are typically coated onto TiO2 surfaces using carboxylic functional groups for attachment [11][12][13]. These groups are crucial for connecting Ru dyes with conventional materials widely used in bulk heterojunction organic solar cells, notably including Fullerene-type compounds such as C60, PCBM, and CNTs [14][15][16].…”
