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