High-efficiency solar cells aim to generate electricity indoors

Places with a lot of direct sunlight are particularly suitable for setting up solar cells to generate electricity. The situation is quite different with artificial light, such as that produced by lamps. This light is usually due to its limited spectrum. inefficient in electrical energy Convert it. Lithuanian researchers have now invented a new solar cell that can do exactly that.

Devices can be charged in the office.

The new cell can handle the limited light spectrum of artificial light. To do this, the researchers combined an organic semiconductor with perovskites. This is how they were able to achieve the efficiency 37 percent When converting LED light with Light temperature 3000K Access.

The lighting intensity in the laboratory is consistent. 1000 lux – The same amount of light as you would on your desk in a well-lit workspace. It's bright outside on a fairly cloudy day for comparison: on a sunny day in the shade in summer it's about 10,000 lux, and in direct sunlight it's about 100,000 lux.

However, the internal solar cells adapt to LED lighting indoors, but their efficiency drops outdoors. They just lie there. 19.1 percentwhich is slightly less than a modern photovoltaic system.

IoT Operation

“Inner perovskite photovoltaics can be used in smart phones, Torches Other electronic devices can be integrated. They can generate electricity under artificial light. “Using IoT technologies, this electricity can be used to make devices operate more efficiently and improve energy consumption,” said lead researcher Astha Dabolini. In a press release.

straight small sensorswhich are connected to the clocks or smart meters in our home, would ideally be powered by a small solar cell. However, since there is not enough light in our interiors, we currently have to use batteries.

The new solar cell is made of a single layer. Perovskite And one Thiazole compound It exists, and may now change. Thiazole is a chemical compound – a so-called aromatic compound that contains nitrogen and sulfur stored in hydrocarbon rings.
