GreatCell Solar recently released a fascinating commercialization schedule for perovskite solar cells, as part of the Company's quarterly report. The schedule includes two timelines, one for glass and one for metal.
The glass section has 2018 as the year in which pilot lines will be set up, and 2019 as a production target. The metal section sees 2018 as a year focused in prototypes, 2019 on pilot lines and 2020 as a production timeline goal. This seems to be an encouraging aim and hopefully the actual progress will live up to expectations. We will certainly stay updated!
