Frequently Asked Questions

Below you can find the answers to questions that we get most often.
Will you sell panels to individual customers?

We focus on B2B (business to business) model, our clients are big industrial players interested in integrating their products with perovskites. Currently, we are not working with individual customers. However, it is possible that our products will be available for individual customers through our client’s distribution network.

When will Saule solar cells be available for purchase?
Our pilot production line is operational since 2nd quarter of 2021. There we can manufacture prototype products for our partners.
What are the possible applications?
We primarily target IoT and small electronics, construction (building-integrated and bulding-attached), automotive and space industries.
Is it possible to invest in Saule?

Earlier this year, the board announced plans to go public in the NewConnect market. All the updates will be communicated through official channels. No additional information will be provided in private messages.

How can we implement perovskite solar cells?

Please visit our Product page to see our developed integrations and get ispired with the Technology page. If you have more questions or a ready idea for a product, do not hesitate to Contact us.

What is the efficiency of Saule solar cells?

Our efficiency in 2021 is around 10% in one sun, and up to 25% in low-light and indoor light conditions. 

What is the lifetime of the product offered by Saule?

We expect an initial lifetime to be several years, which will be improved in due course.

What will be the final shape of the panel?

The inkjet printing technique allows the design of free form perovskite solar modules. The shapes and areas covered by each layer can be all customized according to the requirements.

What does it mean that cells are flexible?

Perovskite cells are resistant to damage caused by bending and folding. The flexibility of the final product depends only on the materials constituting the substrate and the encapsulant. The technology is compatible with virtually any substrate. Currently, developed cells are printed on a flexible, transparent foil.

Can I install perovskite cells on windows?

Yes. Different levels semi-transparency is obtainable. Even though the efficiency decreases with increased transparency, it is still economically viable due to the intrinsically low cost of our technology.

How thick and heavy are your modules?

The thickness of a solar cell is around 1 micron. The total thickness of the module depends on the substrate and encapsulation technology, which is determined by the requirements of the particular application.

The weight of the solar cell is negligible compared to the substrate and encapsulants, and the total mass thus depends on the materials of these components. Current weight of Saule modules is approx. 500 g/m2.

Can you modify the color of the cell?

The technology utilized by Saule enables the finished product to be engineered to a wide range of available colors. This is a feature especially desirable in building integrated applications, allowing architects to design with a great degree of freedom.
