An organic solar cell (also known as OPV) is a type of solar cell where the absorbing layer is based on organic semiconductors (OSCs). Typically, these are either polymers or small molecules. For organic materials to be used in organic electronics, they will need to be semiconducting. .
As with other solar cell technologies, the purpose of an organic solar cell is to generate electricity from sunlight. This is achieved when the energy of light is equal to or greater than the band gap, leading to absorption and excitation of an electron from the HOMO to. .
The first two-component OPV was proposed by Tang (1986) but efficiencies remained very low for several years due to the reliance on bilayer cells. Excitons can only dissociate at the interface between donor and acceptor, and can generally only diffuse. .
One of the primary benefits of organic photovoltaics is that they can be solution processed and could thereforebe suitable for large scale manufacturing with roll-to-roll processing. .
Whilst the efficiencies of OPVs have dramatically increased over the past few years, fundamental limits on their efficiency still remain. A landmark discussion of potential efficiency was published by Shockley and Queisser (1961), where it was. [pdf]
