Photovoltaic modules consist of a large number of solar cells and use light energy (photons) from the Sun to generate electricity through the photovoltaic effect. Most modules use wafer-based crystalline silicon cells or thin-film cells. The structural (load carrying) member of a module can be either the top layer or the back layer. Cells must be protected from mechanical damage and moisture. M…
Understanding how solar cells work is the foundation for understanding the research and development projects funded by the U.S. Department of Energy''s Solar Energy Technologies Office (SETO) to advance PV technologies. PV has made rapid progress in the past 20 years, yielding better efficiency, improved durability, and lower …
