So encasing the cells in glass stopped decomposition? There was no pressure buildup in the cells? No gasses released?

The test says it's 1800 hours of stressful conditions for the cells. Assuming 10h of sunlight per day, that's 180 days of stability. I guess time will tell how long they really last, but it's good news that they surpassed test requirements.

And having a 25% conversion rate baseline compared to a ~26% assumed max for silicon is also impressive. I wonder how much they can boost that.
