Deck 5: Pv Modules

Question 1

The term ____________________ refers to a PV cell configuration in a module where glass is not only used as a supporting structure but also as a window for the illumination of the cells.

Answer 1

superstrate

Question 2

How are the electrical properties of silicon changed?
