at the metal semiconductor contact the transport of minority carriers is describe by surface recombination velocity, what s the surface recombination velocity for electron and hole at the same contact?

its true , for this case the PV module must protect it by bypass diode

[for understand your problem you begin with the cinematic of fluid. for describe any fluid it exixt two types of description lagrangien and euleurien descriptions. where any propriety is write as f=f(x,y,z,t) like velocity v=(x,y,z,t). for calculate the acceleration you use the...

you can see in thermodynamic -''Phase diagram'' http://en.wikipedia.org/wiki/Phase_diagram.

in indirect band gap semiconductors ,the effective mass isn't constant , because of the anisotropie of this effective mass there are (longitidinal and transversal effective mass). for calculate the optical parameters in semiconductor , i need electron and hole effective masses , what the value...
