Skanska, Saule Technologies to install BIPV perovskite modules on office buildings


Sweden’s Skanska Group plans to integrate perovskite solar cells in its office building in Poland. The first tests with the semi-transparent solar cells from Polish provider Saule Technologies are planned for this year.

The company said these will be the first commercial projects in the world to integrate perovskite solar cells into the façade of office buildings. For Skanska, it is another step towards a CO2-neutral office building.

Skanka stated it has the exclusive rights to use the solar cell solutions from Saule Technologies. The signed license agreement applies to building facades and noise barriers in all countries where Skanska operates worldwide. It includes the Scandinavian countries, Europe in general and the United States.

Perovskite solar cells are among the most promising photovoltaic technologies currently. However, there are still many problems with the transfer of research results into mass production for modules.

Saule Technologies has been working on an ink jet printing process for the production of flexible perovskite solar modules since 2014. With this technology, the shape, color and size of the modules could be adapted to the needs of the customers. These modules could also be installed at any free space on a building. They are also stable and water resistant, the company claims.

Saule Technologies has researched its technology in cooperation with international universities in Germany, the United Kingdom, Israel, Italy and Spain. Meanwhile, a Japanese investor is on board. With various research grants totaling more than €20 million, Saule Technologies is currently working on building a large prototype production line.
