Question
Pls answer ASAP
Which of the following statements are TRUE? (a) In a Photovoltaic Cell, incident photon illumination produces a photocurrent in the forward bias direction. (b) In a Photovoltaic Cell, incident photon illumination produces a photocurrent in the reverse bias direction. (c) If the maximum possible current and voltage in a photovoltaic cell arc given byI_m and V_in factor also known as the circuit current is ISC and the open circuit voltage is V_oc. the fill I_m V_m/ISC V_oc. (d) If the maximum possible current and voltage in a photovoltaic cell are given by I_m and V_m respectively, and the short circuit current is Isc and the open circuit voltage is Voc; the fill factor also known as the a measure of the realizable power from a solar cell is given by Isc V_oc/I_m V_m. (e) Amorphous silicon is used for fabricating solar cells because of its low cost of production and high optical absorption coefficient. In this case instead of having hand edges like in single crystal silicon, amorphous silicon is characterized by mobility edges. (f) The mobility of the states above Ec and below Ev in amorphous silicon have a very small value of 10^-6 - 10 cm^2/V-s.
