Ni/N co-doped P25 TiO2 photoelectrodes for efficient Dye-Sensitized Solar Cells

Electrochemical Impedance Investigation of Dye-Sensitized Solar Cells Based on Electrospun TiO2 Nanofibers Photoanodes

“…The enhancement of dye-loading after N-doping was reported by previous studies, including Refs. [ 35 , 53 , 54 ]. In short, N-doping could improve dye-loading, in addition to the electron transfer of the photoanode characteristics of DSCs.…”

“…Additionally, many chemical treatments were reported to improve the efficiency of TiO 2 , such as surface modification [ 31 ], metal doping [ 32 ], or non-metal doping [ 33 , 34 ]. The N-doping strategy could enhance the optical characteristics of the utilized semiconductor in addition to improving the photo-generated electrons’ mobility via decreasing the charge recombination as well as shifting the flat-band voltage of the conduction band, which has a significant impact on both the obtained current (J SC ) and voltage (V OC ) [ 35 ]. According to previous studies, it is reported that N-doping enhances electron transport and broadens light absorption in the visible light area [ 36 ].…”

Investigation on copper–nickel co-doped anatase titania nanospheres as an efficient material for photocatalytic and photovoltaic applications

“…Some of the earlier works are based on Cu and Ni with other metals/non-metals doped with TiO 2 and the efficiency of DSSCs is found to be 2.30%, 9.05%, 11.70% and 0.76% for Fe-Cu/TiO 2 , 40 Cu-S/TiO 2 , 41 Cu-N/TiO 2 , 42 Ni-Zn/ TiO 2 3 and Ni-N/TiO 2 . 43 Similarly, dyes such as methyl orange, methylene blue and Congo-red dye can be degraded by Cu-Zn/ TiO 2 , 44 Cu-Fe/TiO 2 45 and Ni-N/TiO 2 , 46,47 respectively.…”

Eco-friendly Egyptian blue (CaCuSi4O10) dye for luminescent solar concentrator applications

“…One of the constraints with electricity production using conventional Si-based solar cells is the amount of area that is needed for roof-top or stand-alone installations. 1 The lack of flexibility and weight are other challenges that must be addressed to ensure affordable energy for all (i.e., Sustainable Development Goal 7) based on solar cell technologies. 2 Lots of research into solar cells has been focused on novel materials and new processes for solar cell fabrication.…”
