This page presents the lecture videos and associated slides from the Fall 2011 version of the class. The 2011 videos were used to "flip the classroom" for this Fall 2013 version of the course. For lectures 2 through 12, before each class period, students were assigned to watch the corresponding 2011 video lecture below.
The key feature of conventional Photovoltaic PV (solar) cells is the PN junction. In the PN junction solar cell, sunlight provides sufficient energy to the free electrons in the n region to allow them to cross the depletion region and combine with holes in the p region. ...
