Question

1. a pv cell is made of two thin layers of ______.

options:
collector plates
semiconductor material
tubes
insulation

Explanation:

Photovoltaic (PV) cells function by converting light energy to electrical energy through the photovoltaic effect, which relies on semiconductor materials (typically silicon) with different doping in two thin layers to create a p-n junction. Collector plates, tubes, and insulation do not form the core functional layers of a PV cell.

Answer:

○ semiconductor material
