*Cost of PV electricity assumes 2000 hours of insolation, and 6% cost of money, 20 years of system life and 1% annual amortization cost.

• Xtl-Si: Crystallline Silicon
• Thin-films:
  - a-Si - Amorphous Silicon
  - CIGS - Copper Indium Gallium Diselenide
  - CdTe - Cadmium Telluride
  - Tandem a-Si/CIGS
• Presently, thin-film PV modules are one-third the cost of crystalline PV ones.
