Entirely new type of printed
photovoltaic thin-film modules

Flexible, lightweight, transparent, low-cost

About the technology

crystalsol develops an entirely new type of flexible photovoltaic technology. The patented technology combines the advantages of high efficiency single-crystalline materials and low cost roll-to-roll production.

The technology is based on decades of research at Philips semiconductor in the 1960s. The core innovation is the light absorbing layer made of a patented new crystalline semiconductor powder.

The light absorbing active layer of the film is made of crystalline semiconductor particles with a typical diameter of 40 μm arranged as a single layer fixed by a polymer film.

The semiconductor particles contain the abundant and low-cost elements copper, zinc, tin, sulphur, and selenium (CZTS). Every semiconductor particle is coated with an extremely thin buffer layer to create the p/n junction. Before the crystalline powder enters the module production it is already a finished working solar cell. The module production process is based on roll-to-roll technology ensuring high throughput and yield similar to the printing industry.

Consequently the required investment in crystalsol’s manufacturing equipment is significantly below current capital requirements for photovoltaic plants. Main reason is the elimination of vacuum technology for the active layer and the low process temperatures.

Due to the characteristics of crystalsol’s technology upscaling issues – common for thin film technologies – are minimized. As every semiconductor particle is a tiny photovoltaic cell it does not make a difference how large the finished film is. This is an advantage compared to all thin film technologies where all upscaling to larger areas requires costly and time consuming development.


Compared to established photovoltaic technologies.

  • New type of unsealed photovoltaic film for end product integration
  • Flexible and lightweight polymer encapsulation
  • Versatile applications in building integration and consumer products based on custom made sizes and shapes
  • Abundant, non-toxic raw materials copper, zinc, tin, sulphur and selenium as active layer
  • Low cost because of continuous, high throughput roll-to-roll production process from raw materials to finished products
  • Long-term stability due to single crystalline semiconductor structure

Building integrated photovoltaics

The initial focus of crystalsol’s products will be on building integration. The films can either be opaque or transparent for integration into windows, facades and rooftops. They can be laminated with polymer foil for integration in structured facades or encapsulated in glass for higher stability. Due to the simple production process, the films can be tailor made in shape and size.

Consumer products

Besides integration into the building envelope, crystalsol’s products can be integrated into consumer products like mobile chargers, bags, clothing and the like. Due to their flexibility, they can be tailor made to the needs of the consumer product and consequentially, consumer products do not need to adapt to the PV modules available on the market anymore.


crystalsol develops an entirely new type of flexible photovoltaic film with a significant cost and versatility advantage compared to all currently known photovoltaic technologies. The technology is based on decades of research for the Russian military and Philips semiconductor know-how from the 1960s. The core innovations are the crystalline semiconductor powder made from a patented new material and the low-cost roll-to-roll production process.

crystalsol’s technology leads to cost reduction of 30-50% compared to current industry average. This means production cost below 0.3 EUR per Watt peak achievable in the medium term. At this cost level the generated electricity is cost competitive with conventional energy sources.

The technology is based on decades of research for the Russian military and Philips semiconductor know how. In the 1960s Philips Research Laboratories in Eindhoven patented early versions of the technology and used the semiconductor powder approach for the production of light sensitive switches. From this time on Prof. Dieter Meissner was driving the research on the photovoltaic application of crystalsol's technology. Behind the Iron Curtain the Estonian research group of Prof. Mellikov was independently working on the semiconductor powder approach for about 20 years in projects for the Russian military. Joint research of Prof. Enn Mellikov’s and Prof. Dieter Meissner’s groups during the 1990s focused on semiconductor powder made of copper indium gallium diselenide (CIGS). The rising costs of indium led to the search for alternatives. A breakthrough at the Technical University of Tallinn (TUT) allowed the replacement of indium through zinc and tin. Since then crystalsol and its team of scientists are advancing this innovative technology.

crystalsol operates at two locations. Research and development of the semiconductor powder takes place in Tallinn, Estonia. Development of the device and the production process is based in Vienna, Austria.

  • crystalsol OÜ granted with EU Funds under the H2020-LC-SC3-2020-RES-IA-CSA Call September 2020

    CUSTOM-ART aims at developing the next generation of building and product integrated photovoltaic modules (BIPV and PIVP respectively), based on earth-abundant and fully sustainable thin film technologies. Nowadays, BIPV and PIPV are identified as key enabling technologies to make “near Zero Energy Buildings” and “net Zero Energy Districts” more realistic, through the integration of a new generation of photovoltaic modules capable of entirely replacing architectural/mobility/urbanfurniture passive elements. This promising scenario of mass realisation of BIPV and PIPV solutions can only be achieved by developing cost-efficient and sustainable thin film technologies with unbeatable aesthetic functionalities, including mechanical flexibility and optical tuneability. Unfortunately, mature materials already available at the market such as Cu(In,Ga)Se2 or CdTe are formed by scarce and expensive elements (In, Ga and Te), or toxic ones (Cd ). Considering this, CUSTOM-ART will join for the first time a leading group of companies and academic partners all around Europe, to develop advanced BIPV and PIPV products (flexible and semi-transparent solar modules), based on earth abundant kesterite materials, which have been demonstrated in two previous European projects to be at the forefront of emerging inorganic thin film technologies. By combining advanced strategies for materials properties management, with customized modules design in a circular economy approach, two types of products will be developed including flexible PV modules (polymer and steel supports) and semi-transparent (polymer). CUSTOM-ART will bring these technologies from TRL4-5 up to TRL7, demonstrating very competitive conversion efficiencies (20% at cell and 16% at module level) and durability (over 35 years), at a reduced production cost (< 75 €/m2), using exclusively abundant elements and contributing to ensure the full sustainability and competitiveness of the European BIPV and PIPV Industry.
