Researchers have succeeded in adapting solar panels to generate electricity at night. Although production is lower, it would allow isolated locations to run low-power equipment without relying on batteries.
Solar panels are one of the main sources of† Their biggest mistake is that they don’t produce power at night. Usually this production is mixed with other sources that compensate for this weakness, but this is not always possible for installations that are not connected to the † Remote locations would then have to rely on daytime charged batteries, which are expensive and limited life.
Stanford University researchers wanted to solve this problem by creating that produce electricity at night. In an article published in the magazine they describe their prototype consisting of a default to which they added one †
Night production for isolated locations
For a night without evacuate her directly to space, a phenomenon that makes it slightly colder than the surroundings. the thermoelectric uses this temperature difference to produce power. This technique generates only 50 milliwatts of power per square meter, an amount that may seem ridiculous. However, a classic installation on a 20 m² house would already the night.the
The researchers think they can double the yield with a few adjustments and estimate that the maximum theoretical yield can be as much as one or two watts per square meter. Thanks to their invention, isolated installations could do without batteries and produce enough energy to charge a smartphone or provide a power supply low consumption.
