Capturing this energy for our homes and businesses relies on a fascinating scientific principle: the photovoltaic effect. This effect is the fundamental process that transforms sunlight
Customer Service
In addition to the direct photovoltaic excitation of free electrons, an electric current can also arise through the Seebeck effect. When a conductive or semiconductive material is heated by absorption of electromagnetic radiation, the heating can lead to increased temperature gradients in the semiconductor material or differentials between materials. These thermal differences in turn may generate a voltage because the electron energy levels are shifted differently in different areas, creating a potential differen
