Photovoltaics

Photovoltaics is also called PV for short and describes the process for directly converting light energy into electrical energy. Solar cells serve as converters of forms of energy.

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.
