Photovoltaic effect The effect of generating a potential difference in the junction of two materials as a result of visible or other radiation absorption absorption, separation, collection The 3 main steps of the photovoltaic effect http://o.quizlet.com/i/chU2dkB5jUoq8gvmoFWOtw.jpg PV advantages http://o.quizlet.com/i/KMpgvMI8lILhqdHga0DMRg.jpg PV disadvantages http://o.quizlet.com/i/m57eiZem3bdRB38Byv-pag.jpg Generation 1 Technologies that deal with "bulk" crystaline silicon. Generation 2 Low cost thin-film solar cells Generation 3 Concepts aiming at ultra-high efficiency via advanced materials and new conversion concepts. Optical losses spectral mismatch including non-absorption and thermalization. Total reflection and transmission. Other losses recombination, voltage factor, fill factor
