Substitute beer and pizza?

Substitute beer and pizza?. 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 .

Presentation Transcript

  1. Substitute beer and pizza?

  2. 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

  10. Completed Solar Cell
