High-Performance Photovoltaic Solar Cells
About Solar Cells
Solar cells have been developed that can convert ambient light into electricity inside homes, apartments, and offices.
Research about Solar Panels :
A joint group of Swedish and Chinese scientists developed organic solar cells that will convert natural light into electricity in the home. The performance of such solar panels is minimal, but it is enough to provide a lot of gadgets from the Internet of things system.
As the Internet of Things develops its surroundings, millions of everyday devices will need to be connected to the network in homes and common areas, many of them will be equipped with sensors to control temperature, humidity, and other physical parameters. This means that the need will grow for small, cheap in the production and operation of energy sources instead of bulky and expensive batteries.
Organic solar cells can become such a source – they are not only cheap and easy to manufacture due to large-format printing capabilities,
Their light-absorbing layer consists of a combination of donors and acceptors that respond to different wavelengths of light.
Organic solar cells
Organic solar cells created by experts from the universities of Beijing and Linkoping use light waves that match the natural daylight in the rooms. The new photocells are designed in two sizes – 1 sq. Cm, and four sq. Cm. The first responds to lighting with an intensity of 1000 lux and converts 26.1% of the scattered sunlight into electricity; a more significant element has a 23% conversion.
Scientists are sure that in the coming years, the efficiency of organic solar cells can be further improved by optimizing the materials used to create them.
“This work shows great promise for the widespread use of organic photovoltaics in our daily lives to power the Internet of Things,” concluded Feng Gao, a senior lecturer at the Department of Organic Electronics at Linkoping University.
