briefly explain solar power through photovoltaic cells as an strategies for sustainable development?

Solar power is the conversion of sunlight  into electricity  either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic convert light into electric current using the photoelectric effect.Photovoltaic (PV) is a method of generating electrical power by converting solar radiation  into direct current electricity using semiconductors that exhibit the photovoltaic effect .Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. Materials presently used for photovoltaics.
