Current limitation through multijunction solar cell

  1. Dec 13, 2009 #1
    Hi, I've been reading up on multijunction solar cells and found out that since the different layers are connected in series the photo generated current through them must be adjusted so it is the same for each layer to conserve efficiency.

    Why is that?

    Hmm, nobody else has responded yet.

    I'm not quite sure what you are asking. If the layers are connected in series, they must have the same current. That is simply KCL from introductory electronics, there is no separate "adjusting" you can do on the current.

    Can you post a link or quote the source that led you to ask this question?
