Principle of grid-connected solar systems

Feb 28, 2017

Solar PV power is relies on solar component, using semiconductor material of electronics characteristics, dang too Sun irradiation in semiconductor PN knot Shang, due to P-N knot potential base district produced has strong of within built electrostatic field, thus produced in potential base district in the of non-balance electronic and hole or produced in potential base district outside but diffusion into potential base district of non-balance electronic and hole, in within built electrostatic field of role Xia, their to instead direction movement, left potential base district, results makes p district potential increased, n district potential reduced, Thus generating a voltage and current in the external circuit, converting solar energy into electricity.
