Solar cells are thin sandwich of:
Correct answer: A. Semi conductors
- A. Semi conductors
- B. Insulators
- C. Conductors
- D. Wood
Explanation
Solar cells are primarily composed of semiconductor materials.They consist of a thin sandwich or layering of semiconductor materials, commonly made of silicon or other semiconductor materials like gallium arsenide, cadmium telluride, or copper indium gallium selenide (CIGS). These semiconductor materials have properties that enable them to absorb photons (light) and generate electron-hole pairs, leading to the conversion of light energy into electrical energy through the photovoltaic effect.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
