Ideas on solar cell calibration and connection

Previously we have : https://arxiv.org/pdf/1909.13346.pdf

Initial assessment of monocrystalline
silicon solar cells as large-area

Improvements to be made:

Chris tried the silver epoxy wasn't healing properly with oven 

CNS suggested wire bonding 

1. replace the plastic holder design with a different design 
   previously we have 
   
   
   
2. considering this option
   
3. Chris also suggested, "mount a conductor on the Aluminum plate to which the solar cell is glued, and run the wire bonds inwards. That would require, however, making a wire bond with a delta-z of 0.2 inch or so"
   Inquired via email.
   
   
4. Is 3D printing of plastic parts an option? heard seas have free 3D printers?

I'm suggesting that rather than putting the wire bond copper strip on the outside, we mount it on the inside, making no modification to the plexiglass parts we have, like this:

We would have to bend the large solder tabs 90 degrees to connect a wire to it, and it would be a good idea to solder those wires on before the Cu is glued onto the plexiglass part. 
If we do this, we'll have to modify or remake the aluminum pieces but that is easy to do. 
The wire bonder would have to be able to make a connection between planes separated by the combined thickness of the plexiglass and the copper. 
Assembly steps would be:

1. bend one of the large tabs on each Cu strip 90 degrees
2. solder wire onto it
3. glue two of these onto plexiglass part
4. glue solar cell onto plexiglass part
5. do wire bonding
6. glue plexiglass part with solar cell onto Al part.
