This is SUNCURTAIN.

The company specializes in developing photovoltaically active shading systems based on Organic Photovoltaic Technology (OPV), producing OPV curtains for all kinds of applications, and marketing them through its partners.

The central idea is to turn curtains into mini power plants. SunCurtain already presents a classic louvered curtain whose slats consist of flexible, semi-transparent photovoltaic elements. It thus combines a host of different positive properties. The semi-transparency lets enough light into the room so that no artificial light is needed, even when the curtain is closed. And only “cold” light makes it inside. And last but not least, the curtain produces electricity. The print process used for manufacturing makes it easy to adapt designs and formats. 

Blue, green, red and gray are the options available in terms of color and transparency. Surfaces can be matte or glossy.
The louvers also provide great scope for creativity, such as patterns, names or logos.

The curtain offers great potential and new approaches, but we’re also assessing previous systems.

The technology’s impressive life span has a long-term effect on the building system in terms of energy.

The energy obtained can:

+ Be used directly
+ Be temporarily stored
+ Be fed into the building’s local grid, supplying devices across the entire electric circuit

Several prototypes are said to successfully demonstrate how an OPV module can be used as a shading element and particularly highlight every windows hidden potential.

Summer in particular raises the urgent question of the right sun-screening strategy. While everyone wants their home to be filled with natural daylight, no one wants to bear the excessively high inside temperatures that occur on some summer days as a result of no shading. By developing a curtain that not only protects against the overheating caused by incoming solar radiation but also uses this solar energy to produce electricity, the young company SunCurtain GmbH seeks to help boost energy efficiency while simultaneously increasing comfort.

The wide world of electricity-producing curtains

When it comes to helping protect the environment and contributing to the change in energy policy, we need more than “just” improved building efficiency. The behavior of building residents, and a more holistic understanding of buildings in general, is opening up new prospects.

Large areas of glass on buildings with internal shading usually require artificial lighting and air-conditioning, but SunCurtain offers a shading system that doesn’t need artificial light, as the curtain lets enough light in even when closed.

SunCurtain also unlocks an area of application that has previously been neglected: Using windows as power plants.

Coupled with this is the fact that OPV (gray energy) pays itself off environmentally in a few weeks, transportation is fast and efficient, and everything is of “Made in Germany” quality.

SunCurtain gives everyone the chance to be part of the change in energy policy to help solve many different problems. All you need is a window.

The benefits of OPV

SunCurtain has managed to combine benefits such as a low weight, light transmittance, an integrated UV filter, power generation regardless of the sun’s position, and scope for design freedom in one curtain system.

Below are some other SunCurtain benefits:

Reduces the effects of intense incoming solar radiation
+ Reduces UV and IR radiation, meaning better indoor climate
Filtering the warm light spectrum creates stimulating lighting behind the curtain, resulting in an alert working environment
Still lets enough light through, meaning no artificial lights need to be turned on when the curtain is closed
Also extracts energy virtually irrespective of the sun’s angle of incidence

SunCurtain developed a system that absorbs the sun’s energy and makes it available to users, while still reducing the side effects of intense incoming solar radiation. Organic photovoltaics has put itself front and center as the technology of choice for one such solution. Incorporating benefits such as a low weight, light transmittance, an integrated UV filter, power generation regardless of the sun’s position, and scope for design freedom in one curtain system was a completely new and somewhat disruptive approach we wanted to make a reality.

Our product impacts the entire building’s energy, providing added value in the form of power savings, a pleasant atmosphere, and greater building efficiency. The extracted energy can also be integrated into the electronic infrastructure, and directly supply surrounding devices. This so-called direct feed-in means the legal framework is now also perfect for this solution – at least in Germany.

SunCurtain’s aim is to meaningfully help combat climate change – for an independent, sustainable world. It is also revolutionizing the shading market and uncovering hidden potential. Its future product range is set to offer a wide range of solutions and replace existing shading systems.
