Organic Solar Cell is the third-generation technology in the field of photovoltaic and a great achievement in usage of renewable energy in such an efficient and reliable manner. This technology seeks to provide energy at a lower cost than that provided by first and second generation solar cell technologies. Although organic photovoltaic have achieved efficiencies close to 11%, performance limitations and long-term durability continue to be major barriers. It will also highlight the future research challenges. In organic solar cell there is low consumption of material per area which results in easy processing of organic semiconductor offering a huge potential for low cost large area solar cells. From a recent search by the researchers it is being observed that increases in efficiency can be achieved by using luminescent acceptor molecules. According to them, the wavelength at which the sunlight is absorbed can be ‘adjusted’ via the macro-modules used. For example, an office window coated with organic solar cells that absorb the red and infrared spectrum will not only screen out thermal radiation but at the same time will generate electricity. Hence the future research should concentrate on preventing the exciton from decaying which means increase its excitation lifetime. Excitons can decay by emitting light (luminescence) or heat. Multijunction cells are a way to achieve the efficiencies needed. Thin film PV technologies provide numerous ways to reduce manufacturing cost by using high-throughput manufacturing paradigms that don’t require handling of individual silicon wafers. Despite the success of entrenched thin-film PV technologies, organic PV cells attract attention because the electronic and optical properties of organic materials can be changed by altering the molecular structure of the materials.
Therefore here in this article we will emphasise on the efficiency and stability rate as well as how can we get high-throughput by using various organic materials together and what are its atmospheric processing.
