Basic Silicon Solar Cell

• Schematic

3
The process begins with a silicon wafer, (100)
orientation, PRIME grade, 1-20 ohm-cm resistivity
4
Using a spin on liquid phosphorus film as a
dopant source, a n-region is diffused into the
silicon wafer at 950C
5
A metal film is evaporated on the top surface and
a photolithographic mask creates a conductive
grid in the metal
6
A second metal film is deposited on the back for
backside contact
7
Using PECVD (plasma enhanced chemical vapor
deposition) a anti-relective coating of SiO2 is
deposited on the top surface
8
Individual cells are diamond saw cut from the
wafer
9
Electrical testing (I-V trace) of the cell is
performed under a solar light simulator
