Some info about supercapacitors in general: I work as senior engineer at Epishine.

New supercaps have significant leakage current in the beginning of usage, that will of course have impact of discharge time of the supercap with the light cell in complete darkness.

The leakage current will be reduced to specified level after several hours of usage, normal 72 to 120 hours according to manufacturer’s specifications.

Great review.

One thing I learned when reading up on biopolymer printed cells:

sub-optimal panel orientation to the optical flux

The angle of attack isn't important. It's the amount of light energy hitting it, whatever the angle.

Because the material is homogenuous, not crystal-structured like a classic silicon cell.

Good roadtest of the Epishine evaluation board. That was an interesting read.

Judging by your photos, the cell connects via a couple of tracks on the bottom of the flexible pcb. If you cut one of them with a scalpal, perhaps right next to where the track comes off the large square pad so that there wouldn't be any significant damage on the top side if the blade goes through the substrate, you'd then have direct access to the cell by soldering wires to the square pads.
