batteries 48v solar charge controller 60a

   Solar cells are devices that use the photoelectric effect of semiconductor materials to convert solar energy into electricity. 

    The basic process of the photovoltaic effect: #solar regulator controller               Assuming that light is shining on the solar cell and light is received in the interface layer, a photon with sufficient energy can excite electrons from covalent bonds in P-type silicon and N-type silicon, resulting in the generation of electron -Cavity pairs. 

Prior to recombination, the electrons and holes adjacent to the interface layer will be separated from each other via the electric field action of the space charge. 

   The electrons move toward the positively charged N region and the holes move toward the negatively charged P region. #dcdc charger with mppt      The charge through the interface layer respectively will form an outward testable voltage between the P and N regions. 

   At this time, you can add electrodes to both sides of the silicon wafer and connect to the voltmeter. For crystalline silicon solar cells, the typical value of the open circuit voltage is 0.5 to 0.6V. 

   The more electron-hole pairs generated in the interface layer by light, the greater the current. 

   The more light energy the interface layer receives, the larger the interface layer, the larger the battery area, and the larger the current generated in the solar cell.
