Explore the critical stages of silicon purification, wafer fabrication, cell processing, and module assembly, gaining a deep understanding of the scientific principles and engineering marvels behind solar power generation.
Solar cell When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load.
The magic happens through the photovoltaic effect - a process where semiconductor materials generate electrical current when exposed to light. When photons from sunlight hit silicon atoms in solar cells, they knock electrons loose, creating a flow of electricity.
All concentrating solar power (CSP) technologies use a mirror configuration to concentrate the sun's light energy onto a receiver and convert it into heat. The heat can then be used to create steam to drive a turbine to produce electrical power or used as industrial process heat.
At its core, this renewable energy technology uses computer-controlled mirrors (heliostats) to concentrate sunlight onto a central receiver atop a tower, creating temperatures hot enough to melt table salt (literally).
