Photovoltaic device light harvesting material

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. ... [Pg.2078]
