Organic
PV

Organic solar cells show great potential due to their low production costs and mechanical flexibility. These characteristics open up a new range of solar cell applications.

With the emergence of flexible OPVs (for installation on windows, roofs or even in personal belongings) or flexible displays, ITO films are no longer relevant since this material is brittle. GenesInk TranDuctive® is a wet solution printable with standard coating processes and compatible with plastic substrates thanks to its low drying temperature, enabling flexible device manufacturing.

Transparent conductive films must have low roughness to obtain a flat interface between the film and other layers in order to reach superior performances. Roughness below 10 nm is made possible when using TranDuctive® coated films.

For the implementation and mass dissemination of organic solar cells, manufacturing costs, efficiency and long-term stability are crucial. GenesInk solutions are perfect for large area panels in educational establishments or public spaces, which require low sheet resistance.

The production of organic solar cells using solution-based manufacturing processes requires materials such as printable inks which have to meet the following requirements:

– fit with industrial manufacturing processes

– offer higher solar cell efficiency

– available in large amounts of high-quality product

Our  HeliosInk product line covers most of the technologies that are required to manufacture thin, semi-transparent and flexible organic solar cells, from electrodes to charge transport layers.

Perovskite
Solar

Due to the increase in global energy consumption and worldwide environmental issues, it is becoming crucial to explore renewable, efficient, and carbon-free energy technologies. Solar energy is one of the most promising solutions promoting plentiful, clean, renewable and sustainable energy. Today, various photovoltaic technologies are being developed to transform solar energy into electricity. Among these technologies, perovskite solar cells are of high interest due to their enhanced efficiency (up to 20% Power Conversion Efficiency) and to their ability to be upscaled via R2R processes.  There have been 3378 perovskite photovoltaic patents published since 2010, with about 50% of the patents published in China; so far, 568 patents have been granted.

A perovskite solar cell includes a perovskite structured compound (organic-inorganic structure), as the light-harvesting active layer. Perovskite materials are simple to manufacture, and the process can be easily upscaled to acheive low manufacturing costs. Perovskites intrinsic properties – such as broad absorption spectrum, long transport distance of electrons and holes and long carrier separation lifetime – make them very promising materials for solid-state solar cells.

Perovskites possess many advantages, such as:

– They can be manufactured from common metals and industrial chemicals in contrast to the expensive raw materials used in other silicon substitutes.

– Perovskite-based materials can be solution-processed by additive printing technologies and thus allow photovoltaic electronics to be printed directly onto plastics or other materials.

– Spraying or R2R printing of perovskite as a liquid coating allows high volume production and manufacturing of solar cells at a much lower cost than the  silicon solar cells currently used.

– Perovskites have high charge-carrier motilities and long diffusion lengths, allowing the photo-generated electrons to travel long distances without energy loss. Thus, high efficiency can be reached compared to silicon photovoltaics (20%).
