Organic solar cells short-circuit current density

The short-circuit current density in organic photovoltaic cells is limited by a number of photons absorbed in the active layer of the device. Therefore, the active layer materials should exhibit wide absorption spectra to harvest the solar light efficiently and to produce high current densities. Considering the overlap between the absorption spectrum of the device active layer of a certain thickness and the solar AMI.5 emission spectrum, it is possible to estimate the maximal short-circuit current of any photovoltaic device. ...

Many authors have reported different approaches for incorporation of different metallic NPs in organic solar cells (OSCs) i.e. in the photoactive layer, in the hole transport layer (HTL), at the HTL/photoactive layer interface and at the ITO/HTL interface. Fig. 6 shows the schematic design describing these different approaches. We have reviewed the detail literature of photovoltaic performance parameters of bulk heterojunction organic/polymer solar cell. Table 1, 2, 3, 4 summarizes the state of the art reports i.e., open circuit voltage (Voc), short circuit current density (jsc), fill factor (FF) and power conversion efficiency (ti) of plasmonic enhanced OSC devices with NPs embedded between interfacing layers, NPs in the hole conducting layers, combination of different NPs and NPs in the photoactive layer, respectively.
