Enhanced Optical Properties of FeS2 Using Ni@Cu Doping and Characterization of the Structural and Chemical Compositions for Solar Cell Applications

Iron Pyrite in Photovoltaics: A Review on Recent Trends and Challenges

“…% of M) and then decreased with further impurity concentration, demonstrating successful tuning of the band gap. Optical properties were also affected with the incorporation of the Ni@Cu composite increasing absorption in the visible and ultraviolet range . Kumar et al doped iron pyrite with nickel and reduced graphene oxide (rGO) and used the composite in a dye-sensitized solar cell as counter electrode.…”

“…Results of the (a) refractive index, n (ω), (b) complex dielectric function, ϵ­(ω), and (c) extinction coefficient, κ­(ω) of Fe 1– x M x S 1– x thin films. Reproduced with permission from ref . Copyright [2020] Springer Nature.…”

“…Optical properties were also affected with the incorporation of the Ni@Cu composite increasing absorption in the visible and ultraviolet range. 166 Kumar et al doped iron pyrite with nickel and reduced graphene oxide (rGO) and used the composite in a dye-sensitized solar cell as counter electrode. The results showed enhanced efficiency as compared to platinum-based counter electrodes, which was attributed to an increase in a higher electron lifetime and a decrease in charge transfer resistance.…”
