Solar cell converts:
AMechanical
BChemical
CLight to ELECTRICAL energy via photovoltaic effect
DHeat to electric
Answer & Solution
Correct answer: C. Light to ELECTRICAL energy via photovoltaic effect
Solar cell: large-area p-n junction with anti-reflective coating. Photon energy > E_g creates carriers; built-in field separates them, producing voltage ~0.5 V per cell. Efficiency: ~15–25% typical Si; up to 40%+ for advanced multi-junction designs.
