Photogeneration rate
WebApr 14, 2010 · The result shows that thinner solar cell gives higher photogeneration efficiency (64%) due to higher carrier generation near the incident surface while thicker combination of p-type and n-type thickness produce lower photogeneration efficiency (59%) due to the reduction of photogeneration rate in deeper area. The photogeneration rate is ... WebExpert Answer. 4.16 Photodiodes and solar cells are both specially designed PN junction diodes packaged to permit light to reach the vicinity of the junction. Consider a P+N step junction diode where incident light is uniformly absorbed throughout the N region of the device producing photogeneration rate of Gr electron-hole pairs/cms.

http://generation-g.ning.com/photo/albums/company-growth-rates-pdf To understand the electronic behavior of a solar cell, it is useful to create a model which is electrically equivalent, and is based on discrete ideal electrical components whose behavior is well defined. An ideal solar cell may be modelled by a current source in parallel with a diode; in practice no solar cell is ideal, so a shunt resistance and a series resistance component are added to th…
