Saule Technologies perovskite cells achieved 25.5% efficiency.

Laboratory measurements made by Fraunhofer ISE confirmed that Saule Technologies perovskite photovoltaic cells are able to work with an efficiency of 25.5% in operating conditions typical for IoT applications.


Fraunhofer ISE is an independent research institution of undisputed authority, and achieving a yield threshold of over 25% is an important milestone for perovskite technology. Measurements were carried out under 1,000 lux illumination with a cool white LED that simulates the real environment of the first commercial use of these devices.

The results open up new business opportunities for Saule Technologies in Wrocław. Flexible perovskite photovoltaic devices are very well suited for powering electronic devices in low light indoor conditions, making them an ideal solution for various Internet of Things (IoT) applications. Importantly, this futuristic technology is easily available and ready to be implemented on the market, and Saule Technologies, as the first company in the world, managed to move the cell production process from the R&D stage to a full-size production line.

'Our first factory is already printing perovskite devices suitable for the IoT sector. Now that we have successfully entered the commercialization phase, we intend to scale up our business. The time has come to build new factories around the world with much higher production capacity as demand is growing rapidly. The IoT market will be worth USD 1.1 trillion in 2025 and we are ready for it, 'said Dr. Olga Malinkiewicz, co-founder and CTO at Saule Technologies.

The potential of the perovskite photovoltaic technology extends far beyond the IoT market: Saule Technologies cells are also excellent energy sources for BIPV, BAPV, e-mobility and many other business sectors. For example, Skanska is a pioneer in coating the exterior of office buildings with semi-transparent perovskite solar cells supplied by Saule Technologies on a commercial scale.
