A solar (or photovoltaic) cell has two main silicon layers – a top, phosphorus-diffused layer that carries electrons and is negatively charged, and a thicker, boron-doped bottom layer that contains holes, or absences of electrons and is positively charged. The electrical imbalance between these two layers is essentially what makes solar power possible: Light radiation causes each layer’s positive and negative charge carriers to be released in the cells and in turn causes electrical current (direct current) to flow.
In more detail, the process is as follows:
While the process above and solar technology are both extremely complex, fortunately you don’t need to be a scientist to get the benefits of it. To learn more about how solar works or about our panels, please contact a SolarTyme representative.
