The German company Zeiss has developed a technology to equip windows with invisible solar cells. They should have a similar level of efficiency as classic modules.
Zeiss has at CES 2025 presented a new technology that transforms windows into multifunctional surfaces. A holographic film is intended to ensure that both solar cells and cameras become almost invisible. The technology could represent a significant advance in energy storage and camera technology.
The company developed a system that also uses windows as an energy source. A specially developed holographic film is applied to the glass. This directs invisible infrared light onto solar cells in the window frame. The cells then convert the light into electricity.
What’s special: the windows remain almost completely transparent, with a light transmission of over 95 percent. The classic visual transparency of a window is retained while energy is generated at the same time.
Windows with invisible solar cells
According to the company, the efficiency of the solar cells is around 20 percent and almost on par with conventional solar modules. The technology is particularly suitable for buildings with large glass surfaces, such as offices or apartments, and in addition to generating electricity, it also offers easy temperature regulation in the room.
Another product presentation from Zeiss: the so-called “Holographic Transparent Camera”. This camera technology also uses holographic films to redirect light to hidden sensors. The result: invisible cameras in glass surfaces – for example for windshields, screens or access controls.
Especially in vehicles, this technology could improve drowsiness assistants or driver assistance systems without obstructing visibility.
Cameras should be able to be seamlessly embedded into the surfaces
The cameras integrate seamlessly into surfaces, eliminating additional space requirements. Applications range from gesture-based controls to augmented reality experiences in cars and smartphones. With its new developments, Zeiss wants to transform classic surfaces into important components of everyday life.
The solar windows offer a sustainable alternative to generating electricity, while the invisible cameras open up new design possibilities for devices and vehicles. With these technologies, Zeiss wants to demonstrate how holography can enrich everyday life – without attracting attention.

As a Tech Industry expert, I am intrigued by the concept of Solar Window presented by Zeiss. The idea of incorporating invisible solar cells into windows is a innovative approach to harnessing solar energy in a more aesthetically pleasing way. This technology has the potential to revolutionize the way buildings generate renewable energy and reduce their carbon footprint.
The ability to seamlessly integrate solar cells into windows could have a significant impact on the adoption of solar energy in both residential and commercial buildings. It not only provides a source of clean energy, but also offers a dual purpose of serving as a functional window. This could potentially drive greater interest and adoption of solar technology among consumers who may have been deterred by the appearance of traditional solar panels.
I am curious to see how this technology will be implemented and what the potential efficiency and cost savings could be compared to traditional solar panels. Additionally, it will be interesting to see how this innovation will impact the overall design and construction of buildings in the future. Overall, I believe Solar Window has the potential to be a game changer in the renewable energy industry and I look forward to seeing how it progresses.
