Charge separation is a process in which positive and negative charges within a material or system are separated from each other. This separation of charges can occur through various methods, such as the application of an electric field, the absorption of light, or chemical reactions. In the context of research, charge separation is often studied in the field of physics and chemistry, particularly in relation to solar cells, batteries, and other energy storage and conversion devices. Understanding and manipulating charge separation processes is crucial for the development of efficient and sustainable technologies for generating electricity and storing energy. Researchers in this area work to improve the efficiency of charge separation processes to enhance the performance of these devices and reduce their environmental impact.
