Technically, there is no need for special solar cells. In the pilot, we make use of standard silicon solar cells. Of course, the solar cell, the translucent surface and the other components must be adjusted to one another. We develop the SolaRoad concept in such a way that in time we can integrate other types of solar cells, for example thin-film solar cells. A decisive factor for the choice of the best solar cell technology is the economical assessment of costs versus benefit (revenues).
