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
