New: solar modules for indoorsIlumen
Researchers from Sweden and China have succeeded in developing solar cells that convert the light in the house into electricity. Because it concerns indirect sunlight, they provide little power, but just enough to supply smaller devices with energy.
The development is especially interesting for sensors. They can, for example, measure the air quality or the indoor temperature and switch on the ventilation system or the thermostat based on this. But because it is not possible to connect all these sensors separately to the electricity grid, the solar cells can be a handy solution.
The researchers at the University of Linköping also consider the solar cells as decoration. They warn about the limited return.
