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.

Saule Technologies, Columbus Energy and Somfy Polska have signed a strategic cooperation agreement focused on developing innovative solutions for existing buildings and building projects under construction.

This recent agreement finalizes the understanding which the companies made in August 2021 on the occasion of launching the commercial application of Saule Technologies' sun blinds, which are sun breakers with perovskite solar cells.

Saule Technologies has unveiled its new PESL (Perovskite Electronic Shelf Label) technology - the world's first electronic price and advertising labels powered by perovskite photovoltaic cells. The devices enable wireless change of the messages displayed on it, and are said to have lifetimes of around 10 years.

Saule Tech has already released large-scale PSCs intended for building facades, PSC-powered blinds, and now, this new product from the IoT category ' an intelligent system for handling electronic labels, powered by a perovskite solar cell instead of the traditional battery.

Saule Technologies, developer and manufacturer of perovskite solar cells, recently announced that it is 'making good progress towards getting listed on the NewConnect Alternative Trading System'.

Saule and its shareholders, including the majority holder, Columbus Elite Global S.A. (formerly Blumerang Investors S.A.), have signed an investment agreement, setting the rules for Columbus Elite Global (CEG) to acquire Saule's shares. With this transaction, Saule will become part of the CEG capital group, which is listed on NewConnect. In return for transferring their shares to Columbus Elite Global, Saule's shareholders will get shares in the higher share capital of CEG.

Saule Technologies' perovskite-based PV cells have reached 25.5% efficiency, as confirmed by laboratory measurements at the Fraunhofer ISE group of Dr. Uli Würfel.

The measurements were carried out under 1000 lux illumination by a cold white LED, which represents the real-life environment for the first commercial application of these devices.
