The present invention relates to a solar module comprising a front sheet, a transparent solar cell and a structured reflecting layer comprising color patterned portions. The solar cell has a transparency of at least 5%, preferably at least 10%, more preferably at least 20%, said transparency being defined as being transparent to an incident light beam having a wavelength between 350nm and 2µm, said transparency being defined over the whole surface of said solar cell. Moreover, the structured reflecting layer is chosen in such a way that the solar module presents a colored pattern to an observer or to an imaging system positioned to the incident light side of the solar cell. Such solar modules have reflected colored patterns in the visible and /or the near-infra red part of the spectrum and can be easily incorporated into the architecture of the buildings.
