One step closer to the large scale production of flexible, perovskite solar cells


The team of Saule Technologies will present a flexible, printed, perovskite photovoltaic module the size of an A4  for the first time, at the IDTechEx Show! on November 15–16th in Santa Clara, California.

The IDTechEx Show! provides a platform for the demonstration of the latest advances  of nine concurrent technologies and a single exhibition covering 3D Printing, Electric Vehicles, Energy Harvesting, Energy Storage, Graphene, Internet of Things, Printed Electronics, Sensors & Wearable Technology. Saule Technologies is one of 10 winners of the IDTechEx Launchpad initiative on the IDTechEx Show!, which will feature live demonstrations of innovative and emerging products from early-stage companies from all over the world.

Participants of IDTechEx Show! will be shown an operating module printed on an ultra-thin plastic foil able to charge personal electronic devices, demonstrating one of the many possible  applications of the solar cells developed by Saule.

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 Olga Malinkiewicz, PhD, CTO & co-founder at Saule Technologies.

Saule Technologies 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, 1cm2 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. - comments Piotr Krych, CEO & co-founder at Saule Technologies

Thanks to the cooperation with the National Centre for Research and Development, the company created an independent lab-scale production line. 20 scientists and engineers from 11 countries are working on upscaling the production to industry level. The prototype industry-scale production line is expected to be presented during the Autumn of  2018.

SKF has inaugurated its newly-built Sven Wingquist Test Center in Schweinfurt, Germany, an investment totalling EUR 40 million. The center is the first in the world that is able to test large-size bearings under actual operating conditions. This allows for a more efficient development process for customers, as well as improved bearing performance and increased service life.

SINGULUS TECHNOLOGIES is introducing a completely new designed inline sputtering system for ITO and Ag, type GENERIS PVD.  The Heterojunction cell technology achieves conversion efficiencies of more than 22 % as well as reduced manufacturing costs. The newly developed GENERIS PVD system is a horizontal inline sputter tool designed for special requirements in PV high efficiency cell production. A Heterojunction cell performance of 22.3 % was achieved in cooperation with a research institute. The deposited ITO layers exhibit excellent optical transmittance. Charge carrier mobility and electron density are optimized to minimize free carrier absorption in the ITO film. Sputter damage to the amorphous silicon passivation layers did not occur.
