Heat adventure: How PV modules and mirrors conquer nature

Von WOM

In the world of renewable energies, there are always new developments that are not only innovative, but also exciting. One of these fascinating projects deals with photovoltaic modules that not only serve to generate electricity, but also to use the waste heat intelligently. These special modules rely on a combination of heat reflection and microbes to work more efficiently.

The special thing about these photovoltaic modules is that it derives additional heat that is usually unused by using special mirrors. These mirrors are at a precise angle of 45 degrees to the PV modules, which means that they specifically reflect the heat into space. This could be seen as a kind of "heat adventure" in which both the PV modules and the mirrors work together to derive the waste heat efficiently.

The role of microbes

Another interesting aspect of this technology is the use of microbes that act as a condensation nuclei. These small bacteria have the ability to put on water drops so that the dew forms, which then collects on the photovoltaic modules. It is as if the microbes offer a kind of "train station" for water molecules that gather there before they start their way through the PV modules. So the natural condensation is used to win the water back.

The daily cycle of these modules begins when the sun rises. In the morning the PV modules start their work while the mirrors are positioned. At lunchtime, the temperature increases and the mirrors work to lead the excess warmth to space - a really innovative process. In the evening, when the day comes to an end, the dew, thanks to the microbes, collects the day as a cooling greeting.

In summary, this remarkable combination of mirrors and microbes creates a symbiosis that not only increases the efficiency of photovoltaics, but also gives the process a poetic character. The entire idea reminds that even the smallest amounts of waste heat can be converted into creative solutions. This technology makes it clear that nature and technology can work together to maximize the potential of renewable energies.

For interested readers, there is further information on how these technologies have been developed and which prototypes are currently in prospect. In addition, it is explained how architects can benefit from this innovative approach in the design of buildings that are provided with light facades or PV technologies.
