The ultra-light, highly efficient solar cell was developed at NREL (National Renewable Energy Laboratory) and is being commercialized by Emcore Corp. of Albuquerque, N.M. in partnership with the Air Force Research Laboratories Space Vehicles Directorate at Kirtland Air Force Base in Albuquerque.
How many processes occur in a solar cell?
Four consecutive processes occur in a solar cell: (1) light absorption and exciton formation, (2) exciton diffusion, (3) charge separation, and (4) charge transport. Due to the poor mobility and short lifetime of excitons in conducting polymers, organic compounds are characterized by small exciton diffusion lengths (10–20 nm).
What are solar cells based on?
Solar cells based on silicon now comprise more than 80% of the world's installed capacity and have a 90% market share. Due to their relatively high efficiency, they are the most commonly used cells. The first generation of photovoltaic cells includes materials based on thick crystalline layers composed of Si silicon.
How does a solar cell work?
A solar cell (SC) comprises multiple thin layers of semiconductor materials. When sunlight shines on an SC, photons excite electrons in the semiconductor materials, generating an electric current. In recent years, there have been rapid advancements in SC research, primarily focused on improving efficiency and reducing costs.
How to improve the efficiency of solar cells?
Improving the efficiency of solar cells is possible by using effective ways to reduce the internal losses of the cell. There are three basic types of losses: optical, quantum, and electrical, which have different sources of origin.
