Efficiency of a solar cell

  1. Jun 7, 2007 #1
    I recently read that they made a 40% efficient solar cell... what does this actually mean? How do they calculate this efficiency... and how much power do these cells actually produce? and whats with the mono and poly crystalline titles that they get? what does that mean??

    Any info would be helpfull... :smile:

    Next time, when you "read" something interesting and wish to discuss it on here, please cite the EXACT reference. If not, words like "mono crystalline" and "poly crystalline" can have a multitude of meanings!
