Solar cells: Types, Modules, and Applications–A Review

The basic operating principle of photovoltaic (PV) devices is the conversion of solar irradiation into electricity. There are various applications of this principle in many countries such as Egypt, Nigeria and Denmark. Most of the solar PV projects are designed for street lighting, water pumping and water desalination. However, we hope about wide range of using the appropriate components and best technical procedures, standard PV projects with maximum performance output. The present systems now provide 20% to 40% only of the community's heat or lightness on annual basic needs. These include innovative and alternative ways to reduce material uses and module degradation, and opportunities to reuse and recycle PV panels at the end of their lifetime because of the installations of photovoltaic solar modules which are growing extremely very fast.
