Solar Cell MCQ | MCQs on Solar Cell for NEET
Solar cell: A solar cell is a p-n junction diode that transforms sunlight (solar energy) into electrical energy. It works on the principle of photovoltaic conversion. When solar radiations of energy hv >Eģ, (energy gap of the semiconductor), is incident on the p-n junction, they are absorbed by silicon (or Ge), and electron-hole pairs are formed and their flow through the load constitutes the current. Thus the illuminated p-n junction behaves like a battery.
P-I-N diode solar cell: To increase the width of the depletion region, a single crystal of intrinsic material is inserted between P and N extrinsic semiconductors. Thus a P-I (intrinsic) -N diode is formed. It is more efficient than the ordinary solar cell.
