maybe, but I doubt its readily accesible. Depending of course on what type of Solar Cell you mean... (cause there is a heap of cells, cell types, and construction methods http://en.wikipedia.org/wiki/List_of_ty … olar_cells )
PV cells are probably right out.
Buried contact cells maybe, given they've done the nano battery ( http://www.rsc.org/chemistryworld/2013/ … grain-sand )
DSSC, Polymer and Organic Cells - you could probably maybe do the films, but the organic fluid obviously would still be required to be otherwise inserted..
Inside a lab you can probably achieve the required levels of bonded surface finish, but since the current commercial 'metal' or lab 'Si' printing tends to use essentially powdered materials (metal suspended in nylon, etc) glued together in a form of quasi sintering (the glue is UV reacted with the light) - I doubt you'd achieve a surface finish suitable - using current commercial printers anyway. In a lab environment with goldilocks conditions, who knows though ?
Heres an example of the Shapeways materials - as you'll see all the metals end up with a very rough sand-cast-almost appearance..

Anyway - I'm just guessing.... but I suspect that printing an entire functioning cell is well beyond the current reach of the technology...
