Polish company has solar cells with 25.5% efficiency


While most solar cells available on the market are between 15 and 18% of efficiency the Saule Technologies perovskite cells hit 25.5% efficiency. The results are confirmed by an independent lab in Germany, Fraunhofer ISE group of Dr. Uli Würfel.

It is a very important milestone. 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. 

The results open new business opportunities for Saule Technologies, a company based in Wroclaw, Poland. Flexible perovskite photovoltaic devices produced by Saule are very well suited for powering electronic devices in indoor, low-light intensity conditions, making it a perfect solution for various Internet of Things (IoT) applications. What is very important, this futuristic technology is readily available to be deployed on the market, and Saule Technologies, as the first company in the world, was able to transfer the cell manufacturing process from the R&D stage to the full-scale production line and guess what they are 3D printed.

- Our first factory already prints perovskite devices suitable for the IoT sector. Now, when we have successfully entered the commercialization phase, we are going to scale up our business. It is time to build new factories all over the world, with much higher production throughputs as demand is growing rapidly. 

The potential of perovskite PV technology stretches well beyond IoT market, and the first commercial utilization will help mature the technology to reach its full-scale potential, with a wide range of applications.

Saule Technologies cells are also great energy sources for Building Applied and Building Integrated Photovoltaics, e-mobility (solar-powered vehicles), and many other business sectors. For example, Skanska is pioneering a method of covering office building exteriors with semi-transparent perovskite solar cells, provided by Saule Technologies, on a commercial scale. The company says that its solar cells could produce energy even in cloudy conditions.
