What is the effect of tunning A,B,X site on electron affinity of ABX3 perovskite?

As we know bandgap of metal halide perovskite can be tuned by varying the A, B, X sites in perovskite.(mainly by the x site variation ) Is there a similar varition of the electron affinity of the...

Can somebody provide references for the non-radiative efficiency limit of open-circuit voltage,short circuit current, and efficiency of a solar cell?

As We know Shockley et al (1961) derived a radiative efficiency limit for open-circuit voltage, short circuit current, and efficiency of solar cell and found this value to stand at ~30% at 1.1 eV...

Maximum short current density that can be drawn from AM1.5 spectrum for any semiconductor?

Recently I saw a conference paper on a perovskite-based single-junction solar cell. The maximum short circuit density they have obtained is 59.78 mA/cm2. I have studied that the limit to drawing...
