solar cell
A commonly used solar cell structure. In many such cells, the absorber layer and the back junction layer are both made of the same material.
In the context of electronics and photovoltaic systems, these terms describe a hierarchical assembly used to convert sunlight into electricity.12
- Solar Cell: The fundamental building block, typically a few square centimeters in size, that converts light energy into electrical energy via the photovoltaic effect.12
- Solar Module: Generally consists of a series of interconnected solar cells (often 36) laminated to glass and housed within a protective frame.12
- Solar Panel: Formed by wiring and framing one or more solar modules together.12
- Solar Array: A larger configuration created by combining multiple solar panels, often connected via standardized sockets on the back of each panel to increase total power output.12
While individual cells are the primary energy converters, they are combined into modules and panels to boost voltage or current, and ultimately into arrays to meet specific power requirements for stand-alone or grid-connected systems.12
