Solar cells is a light there and be able to respond to convert solar energy into electric power devices. Photovoltaic effect can produce many kinds of materials, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon and gallium arsenide, indium selenium, such as copper. Their power is basically the same principle, it is crystal as an example to describe the process of generating light. P-type silicon crystal doped phosphorus available through N-type silicon, the formation of P-N junction. When the light of solar cells on the surface, was part of the silicon material to absorb photons; the photon energy transfer to the silicon atoms to make electronic transfers have taken place in Vietnam, a free e-P-N in the end both sides gathered to form a potential difference, when the external Access circuit, in the role of voltage, current will flow through an external circuit have a certain amount of output power. This process is essentially: photon energy into electrical energy in the process
