CIGS Solar Cells

Energy consumption in the world is currently continuously increasing, due to the growing population and the industrial development revolution. Currently, energy production mainly depends on fossil fuels (oil, coal, natural gas, etc.), which are non-renewable and limited resources. Their consumption is also a source of many environmental problems, such as pollution and the occurrence of the greenhouse effect. Therefore, it is very important to develop new alternative energy sources that can meet the increasing demand, ensure sustainable development, and preserve the environment. Solar energy is one of the most important candidates to be the energy source of the future because it is an inexhaustible and clean energy source. It is also considered a growing energy source that can cover global electricity needs. In fact, solar radiation can be converted into electricity through devices called photovoltaic solar cells. Photovoltaic (PV) solar cells have many advantages: they are elegant in appearance, environmentally friendly, and silent with no noise.
