Photo Electro Chemical (PEC) solar cells are based on

AOnly inorganic semiconductors

BOnly organic semiconductors

COnly crystal silicon semiconductor

DA hybrid structure of inorganic semiconductors and an electrolyte ✓ Correct

Correct answer: (D) A hybrid structure of inorganic semiconductors and an electrolyte

Explanation

Photoelectrochemical solar cells combine an inorganic semiconductor electrode with a liquid electrolyte to generate current.

They are not built from inorganic semiconductors alone.

They are not made purely from organic semiconductors either.

They do not rely only on crystalline silicon.

The defining feature is the hybrid junction between the semiconductor and the electrolyte solution.

Dye-sensitized solar cells are a well-known example of this photoelectrochemical family.
