Solar cells

A solar cell is a semiconductor optoelectronics component that converts solar energy directly into electrical energy. This process of converting sunlight into energy is that of photovoltaics. Silicon, which largely makes up a solar cell, is specifically mixed with drilling and phosphorus atoms. This creates two electric fields. The silicon-drilling layer is positively charged (p) and the silicon-phosphorus layer is negatively charged (n). . The transition between the two layers is the so-called positive-negative transition (pn).
As soon as sunlight hits a solar cell, an electrical voltage is generated between the connecting cables. This electrical voltage is transported to the external contacts and electrical current flows as if by magic. The higher the brightness, the faster the voltages are conducted to the external contacts and more current is produced than with lower brightness.
