Photovoltaic Effect: An Introduction to Solar Cells
The solar cell is the basic building block of solar photovoltaics. When charged by the sun, this basic unit generates a dc photovoltage of 0.5 to 1.0V and, in short circuit, a photocurrent of some tens of mA/cm2. Since the voltage is too small for most applications, to produce a useful voltage, the cells are connected in series into
Solar Photovoltaic Technology Basics | Department of Energy
In order to withstand the outdoors for many years, cells are sandwiched between protective materials in a combination of glass and/or plastics. To boost the power output of PV cells, they are connected together in chains to form larger units known as modules or panels. Modules can be used individually, or several can be connected to form arrays.
