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.

Perovskite solar panels have been under intensive R&D, and it seems as if commercial production is right around the corner. Some pilot-scale production lines are already functional, and companies are now ramping up production of perovskite panels, using various technologies.

UK-based Oxford PV, for example, recently announced that it has completed the build-out of its 100 MW manufacturing site in Germany, and it is on track to start full production in 2022. China's Microquanta Semiconductor perovskite panel factory is reportedly also nearing production (which should have started late 2020, but updates have not been available since), and another China-based company, GCL, has raised around $15 million USD to expand its pilot-scale production factory to mass production (100 MW).
