I would assume you also want the highest absorption at the P-N junction, so if there is the window layer on top, then the highest amount of light in the absober layer is right next to the junction, and should separate the carriers more efficiently, as opposed to having most of the light absorbed before the junction, and then having the carrier
A range of microstructural changes occur during the deposition and activation of CdTe based thin film solar cells. In particular, the cadmium chloride (CdCl 2) activation treatment results in wholesale recrystallisation which transforms the conversion efficiency of the solar cell.One of the noticeable effects is the change of preferred orientation of the CdTe absorber.
