Saule Technologies will be presenting a flexible, printed, perovskite photovoltaic module the size of an A4 sheet of paper, for the first time, at the IDTechEx Show on November 15-16th in Santa Clara, CA. The operating Saule module is printed on an ultrathin plastic foil able to charge personal electronic devices, demonstrating one of the many possible applications of these perovskite solar cells. The prototype industry-scale production line is estimated to begin in 2018.

"Scaling up the size of perovskite solar cells is one of the biggest challenges for companies and researchers working with this technology. Printing a stable and operating A4 size module has been among our most important milestones for 2017 and we are more than happy to be able to present it for the first time in the USA," says the CTO and co-founder at Saule Technologies.

Saule Technologies says it has pioneered the application of inkjet printing for the fabrication of perovskite solar modules. Increasing the size of the module and the area covered by the perovskite itself is crucial for large-scale production. While it is already relatively easy to obtain small, one-square-centimeter cells operating with high efficiency in laboratory conditions, reaching satisfactory parameters for a module almost 400 times bigger is a significant achievement.

"Some industries of our interest require the modules to be large enough to make the application commercially viable. Scaling the size up is crucial especially when thinking about construction and space industry. The progress we reported so far is sufficient to let us sign the first cooperation agreements with future clients," says the CEO and co-founder at Saule Technologies.
