Trading Halt, page-27

This is 27.3% for a 1 cm² tandem silicon+perovskite lab cell, compared to 26.7% efficiency for a silicon cell alone. Why bother?

Not really much to be scared about from Cambridge yet, and in any case there's plenty of room for multiple players. I believe in this case GSL is way ahead in the upscaling and commercialisation process, and while I once thought tandem cells might be a good idea, I think GSL is on the right track starting with straight perovskite panels and getting it right - KISS.

I'm still a bit nervous waiting for the Turkey deal to finally be completed, but apart from that I'm feeling as hopeful about GSL as I ever have (and I've held them for 9 years).
