Energy is the driving force for economic development, modernization, and automation. Currently, the world’s energy sources are mainly supported by fossil fuels. However, fossil fuels result in the depletion of natural resources and CO2 emissions. To address this problem, Dye-sensitized solar cells (DSSCs) are a promising solution to global energy and environmental issues. DSSCs can convert solar energy into electrical power leaving no environmental effect. In addition, DSSCs have attracted a great deal of attention due to their low-cost, simple fabrication process and some other attractive properties, such as vivid color, transparency, and acceptable response at low irradiance. Therefore, Lectro Solar Cell conducts research and development of DSSCs for indoor and outdoor power generation applications.
