Electricity Notes
... B. There are two kinds of basic circuits: series and parallel. 1. A series circuit has only one path for the electric current to follow—if the path is broken, the current will no longer flow and all devices in the circuit stop working. 2. A parallel circuit has more than one path for the electric c ...

Theory of solar cells
The theory of solar cells explains the physical and chemical processes by which photons are converted into electric current when striking a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
