4000w off grid solar inverter

  The photoelectric conversion of solar energy refers to the process in which the photons of the radiant energy of the sun are converted into electrical energy through semiconductor materials, which is often called the "photovoltaic effect". 

  Solar cells are made using this effect.#4000w inverter pure sine wave          When sunlight hits the semiconductor, part of it is reflected off the surface, and the rest is absorbed or transmitted by the semiconductor. 

  Of course, some of the absorbed light becomes heat, while other photons collide with the valence electrons that make up the semiconductor, so electron-hole pairs are generated. 

  In addition to offsetting the barrier electric field, a part of the photogenerated electric field also makes the P-type layer positively charged and the n-type layer negatively charged. 

  The so-called photovoltaic electromotive force is generated in the thin layer between the n region and the p region. If metal leads are soldered to the P-type layer and the n-type layer respectively, and the load is connected, a current will pass through the external circuit. 

  The battery elements formed in this way, when connected in series and parallel, can generate a certain voltage and current, and output power.
