Definition and context
A photovoltaic cell uses a semiconductor to generate and collect charge carriers from light. The current produced depends on both the device and the radiation it receives, as well as its operating conditions. Several cells can be integrated into a module.
An image of an isolated cell is useful for understanding the principle, but an installation adds connections, protections, and electronics. If we find an efficiency percentage, we should check what level it refers to and how it was measured. A small experimental cell and an outdoor-use module are not interchangeable objects. This distinction makes it possible to assess a laboratory advance without attributing properties to it that still need to be demonstrated in other tests.
