Saule Technologies is a Polish start-up that designed a low-temperature method for manufacturing flexible photovoltaic perovskite cells. The company is working on the development of a flexible and semi-transparent cell based on PET foil.
Saule's aim is to combine perovskite solar cells with other currently available products.
Saule Technologies has been working on the application of ink-jet printing for fabricating free-form perovskite solar modules since 2014. This technique allows the shapes and areas covered by each layer to be customized according to requirements. The stability and water resistance of the modules make them ideal for the construction industry. The company has conducted advanced research on perovskite applications in solar energy harvesting and optoelectronics with leading international universities in the UK, Israel, Germany, Italy and Spain. With a Japanese investor on board, along with support from the Polish National Centre for Research and Development and several research grants worth more than EUR 20 million, Saule Technologies is working on a large-scale, prototype production line.
Saule Technologies has extensive R&D work going on, with many collaborations and even early-stage product launches.

Researchers optimize a blade coating process to achieve 12.6%-efficient nickel oxide-based large-area perovskite solar modules
Researchers from CHOSE (Centre for Hybrid and Organic Solar Energy) at Tor Vergata University of Rome, CNR-ISM and Saule Technologies have introduced an optimized blade coating process for the scalable fabrication of large-area (15 cm × 15 cm) perovskite solar modules with a nickel oxide hole transport layer, performed in ambient air and utilizing a non-toxic solvent system.
The research group fabricated a 110 cm² perovskite solar module with an inverted configuration and a hole transport layer that uses nickel oxide instead of commonly utilized poly(triarylamine) (PTAA). The proposed architecture aims to achieve high efficiency that is competitive with PTAA-based panels while improving stability.
New in situ fabrication technique could yield high-performance blue LEDs
Researchers from North China Electric Power University, Beijing University of Chemical Technology and Sichuan Normal University have created bright blue perovskite LEDs (PeLEDs), among the LED colors needed to enable commercial applications.
With high efficiency and stability, PeLEDs could be a promising new option for full-color displays and solid-state lighting technology. However, while red and green PeLEDs have nearly reached their theoretical external quantum efficiencies, blue PeLEDs do not yet reach the efficiency, stability, or luminosity required for commercial applications. The novel method presented in this work seeks to address this challenge. Using an in situ spin-coating method, the authors created Dion-Jacobson phase quasi-2D perovskite nanocrystals. A mixture of mixed inorganic cesium bromide and two organic bidentate molecules in the perovskite precursor solution regulates growth and crosslinking in the nanocrystals. The resulting perovskites demonstrated effective emission in PeLEDs, brightly glowing from sky blue to deep blue.
Researchers develop method to create layered perovskite nanowires with unusual optical properties
Researchers from Purdue University and ShanghaiTech University have developed a patent-pending method to synthesize high-quality, layered perovskite nanowires with large aspect ratios and tunable organic-inorganic chemical compositions.
The novel method creates layered perovskite nanowires with exceptionally well-defined and flexible cavities that exhibit a wide range of unusual optical properties beyond conventional perovskites.

Ergis readies a novel encapsulation film for perovskite solar panels
This is a sponsored post by Ergis Group
In 2020, Poland-based Ergis Group launched the noDiffusion film platform, a high-barrier film that offers high level of optical transmittance and low level of light scattering, and the ability to contain transparent conductive electrodes. The new technologies adopted in the production of the barrier films offer a combination of high performance and competitive pricing.
Following years of R&D, Ergis is ready to enter production with its first-gen barrier films, produced using sputtering in a roll-to-roll (R2R) configuration. The company reports performance of around 10-4 wtr performance for its barrier. This is referred to as a "light-barrier" and one that is more than enough for the encapsulation of perovskite materials. The company collaborated with Poland-based Saule Technologies to develop this specific film. Ergis is now shipping barrier film samples to its customers.
