Perovskite PV technology has moved forward in leaps and bounds in recent years, with cell and module efficiencies quickly growing from just a few percent to figures that match and even surpass the performance of commercial silicon and thin-film products.
Though stability has improved at a similar pace – the first perovskite PV cells, fabricated a decade ago lasted only minutes – the issue remains a key concern and one which has prompted caution among manufacturers taking an interest in the technology.
The latest announcement from European solar research organization Solliance, however, could ease stability concerns. Solliance, which incorporates Dutch research organization TNO and Belgian counterpart imec, claims it has put perovskite modules made on its pilot production line through rigorous stability tests and achieved impressive results that would meet industry standards.
