Haha, very good.

In fact, we had some equipment similar to that on this site https://solarlight.com/product_category/products/solar-simul...

Basically a super bright light source with a similar spectral output to our sun. A roughly 1x1cm solar cell in a nitrogen filled chamber is wired up to check the output under the incident light. Very cool production process. I was extremely lucky to have had the opportunity to help with the research.
