Anyone has the same question as I do? I am in the second lecture, but why the bias added in this serial is different from what I have known? Why the bias is forward? Dark current is always refer to reverse bias, isn’t it?

Not only did Prof Lundstorm share his knowledge, he also shared his wisdom with very insightful explanations of various physical phenomena occurring in solar cells. Specially, for me, his emphasis on “recombination leads to current” added an independent perspective of looking at a diode. One the downside, it took me a few thinking moments to realize why recombination is bad when it leads to current especially while I was watching the video the first time. All made perfect sense at the end of the lecture anyway when the difference between dark and light current was explained :).
