       The photovoltaic cell is a kind of light and electricity conversion characteristics of semiconductor devices, it will directly convert solar radiation into DC, is the most basic unit of photovoltaic power generation, electrical characteristics of photovoltaic cells is unique in crystalline silicon with the incorporation of certain elements (e.g. phosphorus or boron), resulting in permanent imbalance the molecular charge material, forming a semiconductor material with special electrical properties of semiconductor, with special electrical properties in the sunlight can produce free of charge, these charge free directional move and accumulation, and thus the electric energy generated at its both ends are closed, and this phenomenon is called "photovoltaic effect" referred to as photovoltaic effect.
