where FF is the fill-factor, V oc is the open-circuit voltage, J sc is the short-circuit current, and S AM1.5G is the incident power from the AM1.5G solar model:100mW/cm2. The fill-factor is related to the maximum power-point, where the …
About Photovoltaic Energy StorageTable 1 shows the analytical expressions, similar to that in Ref. [13], of the energy losses related to the effects mentioned previously.These loss mechanisms are depicted in Fig. 1 which shows how the energy of the incident photons is converted within an ideal p–n junction solar cell. The first two losses are related to the spectral mismatch …
