Saule Technologies

Saule Technologies has announced that it will work with H.I.S. Co., Ltd. and Lawson, Inc. to start a pilot demonstration using film-type perovskite solar cells at "Green Lawson" from Monday, December 16, 2024.

Lawson is a large chain of retail grocery stores based in Japan, and it was stated that the cooperation will include Perovskite Electronic Shelf Labels and Power Generation Panels.

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.

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 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.

Saule Technologies has announced that yesterday, November 11, the SpaceX Falcon-9 rocket with mission Transporter-9 was launched, carrying its perovskite cells to the Low Earth Orbit.

Saule Technologies stated that its team has put in immense work researching, developing and creating the perovskite-based PV module adapted for tests in space conditions.

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.

A new European project focused on perovskites has been launched, called “EFESO” (Exploiting Flexible pErovskites Solar technOlogies). It is a new fully funded
Horizon-Europe project, lead by Dr. Luigi Angelo Castriotta, Post Doctoral fellow of the University of Rome Tor Vergata.

The project aims to advance the upscaling of stable Flexible Perovskite Solar Modules (FPSMs) by optimizing fabrication processes on flexible substrates, reducing inactive areas on modules and working on lead (Pb) trapping intrinsically, using doping and interface engineering, and extrinsically by
encapsulation strategies.

Researchers from Saule Research Institute, Saule Technologies, Centre for Hybrid and Organic Solar Energy (CHOSE), CNR-SCITEC, Istituto Italiano di Tecnologia (IIT), Wroclaw University of Science and Technology, Bydgoszcz University of Science and Technology and Poznan University of Technology have demonstrated an effective strategy to improve the technical aspects of flexible perovskite solar cells,  improving the reliability and efficiency values of these devices.

The team applies large organic ammonium molecules for modifying a buried interface between a hole-transporting layer (HTL) and perovskite-absorbing material. With the 4-fluorophenethylammonium iodide (FPEAI), they achieved 18.66% efficiency for the large-area (1 cm²) flexible solar cell, a significant improvement over the pristine device without modification.

Saule Technologies recently shared that its PESL (Perovskite Electronic Shelf Label) technology - electronic price and advertising labels powered by perovskite photovoltaic cells - have been installed at Żabka Eko Smart in Poznan, Poland. In addition, the same venue sports Saule's blinds that allow for generating energy from both natural and artificial light.

Saule shared that these unique technologies are aimed at improving the work of Żabka stores and increasing the comfort of customers and employees while maintaining care for the environment. 

Saule Technologies and Columbus Energy have partnered with Google Cloud, signing a strategic cooperation agreement to develop new products using perovskite solar cells and solutions in the field of distributed energy and IoT (Internet of Things). Google Cloud will also become a strategic partner of both companies, providing cloud computing services and technologies.

The concept behind IoT is to connect a variety of often small and highly-specialized electronic devices in a network so that they can generate and send information to each other. However, such devices require power and this has greatly limited their potential applications to date. The perovskite solar cells developed by Saule Technologies are not only lightweight, thin and flexible, but they are also able to perform well even in artificial light. These unique advantages make Saule Technologies cells "the perfect energy source for all kinds of IoT devices in virtually all conditions, regardless of power grid availability", according to the Company's statement.
