GI series 3kw 4kw 5kw low frequency inverter

    The basis of the working principle of solar cells is the photovoltaic effect of the semiconductor PN junction. The so-called photovoltaic effect is an effect in which electromotive force and current are generated when the object is illuminated, the state of charge distribution in the object changes. When sunlight or other light hits the PN junction of the semiconductor, a voltage appears on both sides of the PN junction, called the photogenerated voltage.

   When light is irradiated on the pn junction, electron-hole pairs are generated. The carriers generated near the PN junction inside the semiconductor are not recombined and reach the space charge region. Attracted by the internal electric field, electrons flow into the n region and holes Influx into the p region, resulting in excess electrons stored in the n region and excess holes in the p region. They form a photogenerated electric field near the p-n junction opposite the direction of the potential barrier. In addition to partially counteracting the effect of the barrier electric field, the photoelectric field also makes the p region positively charged and the N region negatively charged, and an electromotive force is generated in the thin layer between the N region and the P region, which is the photovoltaic effect.
