Newer approach of using alternatives to (Indium doped) metal electrodes, dyes and electrolytes in dye sensitized solar cell

Effect of using betalain, anthocyanin and chlorophyll dyes together as a sensitizer on enhancing the efficiency of dye‐sensitized solar cell

“…Aluminium doped zinc oxide (AZO) was utilized as charge collectors for the photoanode as per our previous findings 24 . The optical band gap of AZO is 3.3 eV in comparison to that of 4.9 eV of ITO‐indium doped tin oxide and 4.3 eV of FTO.…”

“…Aluminium doped zinc oxide (AZO) was utilized as charge collectors for the photoanode as per our previous findings. 24 The optical band gap of AZO is 3.3 eV in comparison to that of 4.9 eV of ITO-indium doped tin oxide and 4.3 eV of FTO. It helped in utilizing the solar energy to the highest since the doping of aluminium in zinc oxide resulted in the proper adsorption of dye thereby giving the best efficiency.…”

“…22,24,[28][29][30][31] Polyaniline was used since as per our previous findings it helped improve the carrier transportation ability of electrolyte and thereby increased the overall efficiency of the cell. 24,29,32 3.3 | Preparation of dye sensitizers 10 mg of N3 dye powder was added to 30 mL of anhydrous ethanol for 20 hours to prepare the N3 (standard dye) solution. 5 g each of O sativa L. and H sabdariffa (Manipur and Assam) were used to extract Anthocyanin (A), B vulgaris for Betalain (B) and S oleracea, C sativum for Chlorophyll (C).…”

“…Hence the cells made from the mixed dyes are expected to show better efficiency than those based on single dyes due to active sensitization. 24 Similarly, further mixing of all three dyes [ABC] showed all peaks of individual dyes, have offered strong absorption primarily in the middle segment and a broad range by gathering the energy from the two ends of the visible light and indicated the dominant behavior of anthocyanin dyes. The broader and more intense light absorption nature of mixed dye is likely to provide a higher efficiency than that of single dyes.…”

Enhancing the efficiency of dye-sensitized solar cell by increasing the light trapping and decreasing the electron-hole recombination rate due to Ag@TiO2 core-shell photoanode structure

“…Crystalline silicon SCs, representing about 90% of the world productions are known as the first generation SCs. However, researchers showed the computational PCE of silicon SCs would be restricted to 37% [1][2][3][4]. Inexpensive, scalability for mass-production, and light-weight flexible thin film modules like CdTe, CdSe, IGO, CIGS and amorphous silicon (a-Si) are among the most popular second generation SCs.…”
