Part b):Find the number of electrons produced in the semiconductor material.
Photon Flux & Renewable Energy:
The follow question involves the photon flux of a light source shown in Figure1.: From the graph presented below, the photon flux of light consists of 3 cm^2 Cross Section Area.
The light operated only for 2 seconds to illuminate a semiconductor (the semiconductor has a Cross-section Area of 2cm^2 and an energy band gap E gap = 1.1 e V)
Homework Answers
E = 1.2eV and 1.4eV are the only values which will generate electrons since they are > E gap.
Number of electrons generated = Total number of photons corresponding to 1.2eV and 1.4eV
=
= 100*2*2 + 200*2*2
= 1200
