In order to resolve serious global environmental problems such as the greenhouse effect and acid rain, the key lies in the development of clean energies. Solar cell, which converts sunlight directly into electricity through the photovoltaic effect of semiconductors, is a key technology to overcome global environmental problems. This paper will review recent advances in solar cell technologies and their application technologies. Finally, future prospects are also reviewed, including a new global energy supply system called the GENESIS.
