And if you click on the wikilink to CIGS you can read the following; "individual cells are divided and monolithically interconnected by a series of scribing steps between the layer depositions"
The XsunX 125 mm square substrate is NOT the same size as a CIGS cell, it is much larger. Multiple CIGS cells will fit on the 125 mm square area. The CIGS cells must be created on the larger substrate EXACTLY as it describes on wiki.
In the industry, it is common to use the term cell when talking about the smaller individual cells created by scribing, and likewise, use the term cell when talking about the larger device that results from the algimation of these smaller cells.
For the language challenged let me illustrate:
small solar cell + small solar cell + small solar cell + small solar cell = large solar cell
So my question for XsunX remains the same, did you create one "small" CIGS solar cell at 15.1%, or, did you make a 125 mm square CIGS "large" solar cell with ALL of the "smaller" cells on it at 15.1% or better?
Quick research on Google finds that the optimum width of a CIGS cell is between 5 mm and 10 mm, so there is at least somewhere between 12 and 24 CIGS cells on the XsunX 125 mm square substrate. END OF STORY.
