    I love how nicely he is teaching everything: explaining, playing, and smiling! :) Wish I was in his class!

    I wish be present in an MIT class like this once in my life. It’s an experience I really wanna live. Excellent classes!

    Thanks professor. Thanks MIT

    This lecturer is excellent but I would suggest that he really means electrochemical potential rather than chemical potential when discussing the materials under bias conditions. It's subtle but might avoid confusion.

      Yeah I made the same comment in the previous lecture

      He said that Femi energy is chemical potential. That is correct.

      Electrochemical potential is the difference between the bottom of conduction band and chemical potential. It is consistent with prof. Chen gang's talking. Driving force V is related to chemical potential which is shown in prof. Buonassisi's equation. Nothing is wrong.

    25:00 why a load has to be matched to the solar cell, one of the reasons why water electrolysis powered by PV should be run at around 10 mA cm-2. Good explanation, Prof.

      at 34:00 he explains this further, match the load and ilumination conditions to operate at maximum power.

      Hi, perhaps you could be so good as to clarify the biasing with a load. The question was asked at 24:20 about how a load biases a device? Does a load cause a reverse bias? And this reverse bias needs to be somehow balanced by the forward bias (from illumination), to ensure operation at the voltage and current to ensure maximum power output? (which the lecturer discusses at 34:20). Thanks @@DDDelgado

    2:00 nice to see the absorption curve of the chlorofil, little absorption at 550 nm where the maximum solar flux of energy is at.

    I realize I am a bit late to the game, but is there any chance anyone knows the paper he references @35:50 about the limits of Voc?
