The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
The back reflector of thin-film silicon solar cells often consists of atextured metal surface separated from the silicon layers by a thin dielectric layer (e.g. ZnO). Despite the high reflectivity of the textured ZnO/Ag back reflector, parasitic absorption losses exist in both the ZnO and Ag layers.
The first part 1 namely about 30%, is reflected, also at 35° (angle of incidence = angle of reflection) and impinges on an adjacent pyramid, whereas the second part 2, namely 70%, is refracted into the antireflexion coating (ARC) at an angle of ~24° and then enters the solar cell at an angle of ~12°.
Portable and emergency devices: Solar cells are used in portable chargers for mobile phones and emergency equipment, ensuring power supply in critical situations. Photovoltaic cells are responsible for transforming light into electrical energy and are the basic component of photovoltaic modules.
This process is called the photovoltaic effect. Solar cells are essential for photovoltaic systems that capture energy from the sun and convert it into useful electricity for our homes and devices. Solar cells are made of materials that absorb light and release electrons.
