Real photo diodes do not precisely obey the ideal photo diode equation (25.17) A more realistic model
Question:
Real photo diodes do not precisely obey the ideal photo diode equation (25.17)
A more realistic model is the non-ideal photo diode equation
where m > 1 is the ideality factor. Consider a non ideal photo diode with m = 2, Voc = 0.7 V. Compute Iphoto/I0 and the fill factor. Compare the efficiency with an ideal photo diode with m = 1 and the same open circuit voltage.

As a tutor, I have gained extensive hands-on experience working with students one-on-one and in small group settings. I have developed the ability to effectively assess my students' strengths and weaknesses, and to customize my teaching approach to meet their individual needs.
I am proficient at breaking down complex concepts into simpler, more digestible pieces, and at using a variety of teaching methods (such as visual aids, examples, and interactive exercises) to engage my students and help them understand and retain the material.
I have also gained a lot of experience in providing feedback and guidance to my students, helping them to develop their problem-solving skills and to become more independent learners. Overall, my hands-on experience as a tutor has given me a deep understanding of how to effectively support and encourage students in their learning journey.
