Theoretical Study of One-Intermediate Band Quantum Dot Solar Cell

Figure 2

The left-hand side of (9), (𝜖), against 𝜖 at fixed values of 𝜇 and 𝐴. This graph shows allowed and forbidden electron energy bands for the simple cubic QD with the quantum dot width 𝐿_QD=4.5 nm (InAs_0.9N_0.1, 𝑚_𝑄=0.0354𝑚₀), barrier width 𝐿_𝐵=2nm (GaAs_0.98Sb_0.02, 𝑚_𝐵=0.066𝑚₀), and 𝑉₀=1.29 eV.
