Solar panels, or photovoltaic cells, convert sunlight energy into electricity. Their construction is based on semiconductor materials, most often silicon.
When photons of sunlight hit the surface of the panel, they excite electrons in silicon, causing charge movement and thereby creating an electric current.
The development of this technology began in the 1950s: initially, panels were used to power satellites, and today they have become widely used in households and industries.
Modern panels can generate up to 1000 watts of energy per square meter on a clear sunny day, making them a key element in the transition to renewable and environmentally friendly energy sources. However, further research aimed at increasing efficiency and reducing production costs is required for their mass accessibility.
