Short-Circuit Current Density
Short circuit current density J sc (mA/cm 2) term is generally used in solar cells rather than short circuit current to remove the dependence of the solar cell area. Although organic semiconductors have high absorption coefficients, their absorption range is mostly between 350 and 650 nm which brings in the mismatch between the organic semiconductors and …
