Cigs band diagram
WebApr 13, 2024 · As a matter of fact, the band diagram of solar cells structure can be obtained by using SCAPS-1D software program. In this respect, the band diagram of the new ultra thin CIGS structure solar cells has been computed using SCAPS-1D code. Our results are displayed in Fig. 2. One can observe that there is a good band alignment between Si … WebTable 4 shows the variation in band gap, electron affinity, and cell performance due to the change in Ga fraction. In a good agreement with simulation result, the optimal band gap of the CIGS absorber was chosen as 1.21 eV while the electron affinity was calcu-lated as 4.21 eV. Because the band gap greater than 1.21 eV causes reducing the absorp-
