Researchers print module six times bigger than previous largest

2. 10. 2018 | Tech Xplore | www.techxplore.com

A perovskite solar module the size of an A4 sheet of paper, which is nearly six times bigger than 10x10 cm2 modules of that type reported before, has been developed by Swansea University researchers, by using simple and low-cost printing techniques.

The breakthrough shows that the technology works at a larger scale, not just in the lab, which is crucial for encouraging industry to take it up. Each of the many individual cells forming the module is made of perovskite, a material of increasing interest to solar researchers as it can be made more easily and cheaply than silicon, the most commonly-used material for solar cells.

Super big solar cells

Perovskite solar cells have also proved to be highly efficient, with scores for power conversion efficiency (PCE) - the amount of light striking a cell that it converts into electricity—as high as 22% on small lab samples.
