1. It will decrease due to decrease in collector current.A /r2. IS - A/ . M, ('.A/., 120 x 100 x 10 Aâ– 12 * 10 3 A3. Reverse biasing.4. (0 for rt-type . arsenic. (/'/') forp-typc. IndiumTruth TableABY - A + B0010101001107. (a) Diode is reverse biased because /?-type of thediode is at lower potential. (.b) Diode is reverse biased because p-typc of the diode is at lower potential.(c) Diode is forward biased because p-type of the diode is at higher potential.(d) Diode is forward biased because p-type of the diode is at higher potential.8. In n-type semiconductor charge carriers are electrons and mobility of electrons is more than that of holes.9. 1. Band gap 2. Biasing 10.16. It's more than one.17. p-type18. Energy gap decreases.19. Width decreases.20. Width of depletion region increases.21. Solar cell is a device for converting solar energy into electricity. It is basically a.p-n junction operating in a photovoltaic mode. When light photons fall at the junction, electron-hole pairs are generated. These move in opposite directions due to junction field. These charges accumulate at the two sides of the junction and photo-voltage is developed. It is used in calculators etc.
