FILD-PV brings color into the world of photovoltaics, offering innovative solutions for the use of solar modules in particularly sensitive environments – namely, in monument, townscape and landscape protection zones. The focus here is not exclusively on generating as much energy as possible from sunlight, but also on how this technology can be designed to be visually appealing and aesthetically pleasing to fit into historic districts and protected landscapes without detracting from their appearance. This is the only way to increase acceptance among architects, building owners, authorities and, above all, the public.
One of the biggest challenges with colored PV modules is the power loss caused by the coloring layers (= lower efficiency). This is due to the fact that the dyes or coatings used absorb part of the sunlight and this portion is therefore no longer available for generating electricity in the cell.
Project goals
But this is precisely where the FILD-PV project comes in: the aim is to examine all coloring PV materials and technologies available on the market in a comparative manner. The aim is to determine the relationship between color and power loss on the one hand, and the material compatibility and long-term stability of the products on the other. This data and information on colored PV are to be made available to all stakeholders and thus enable the harmonious integration of high-performance colored solar systems.
Particular attention is being paid to the development of reliable, long-term stable material combinations for color-matched PV installations. These studies should ensure that the colored solar modules not only look good, but also withstand the stresses of time. Aging tests play a decisive role here, in which the PV modules are tested under extreme conditions (e.g. temperature, humidity, UV radiation, electric field/charge) to ensure that over time there are no changes in color, brightness, homogeneity or adhesion, which would have a major impact on the external appearance of the PV installation.
The development of colored solar modules that are both efficient, durable and aesthetically pleasing – specially adapted for use in monument and landscape protection zones as well as urban areas – is a crucial step towards achieving the climate goals and forms the core of this project.
