A team of Chinese researchers has developed a solar cell that converts 34.58% sunlight into electricity, which sets a new record for the silicon-perovskit-tandem technology.
Silicon-Perovskit-Tandem solar cells combine traditional silicon, which used in most commercial solar modules with a layer of perovskit, a crystal-like connection that fights for efficient sunlight and in wavelength silicon to catch.
According to Tech Xplore, according to Oxford PV, the Perovskit-Silicon Tandem Solar Cell Technology is pushed closer to the theoretical limit of around 43% efficiency.
For the context, the solar modules perovskite-on-silicon improved to 25% efficiency in 2015 in 2024 in 2024.
Standard silicon plates cannot hold all light wavelengths. Perovskit, an inexpensive material known for the absorbing of blue and green light, can fill some of the band gaps in silicon.
In the study published in the Nature magazine, the researchers combined a silicon solar cell with a thin, self-organized layer Perovskit to create a tandem design that in turn made the panels remarkably efficient.

According to the University of Rochester, perovskit materials are to be produced cheaper than silicon, which could help reduce the total costs of solar collectors.
If they are enlarged, the technology could also reduce the costs of solar energy by capturing more light and creating more electricity from the same surface. This further development could make an affordable and harmful air pollution on the roof, which improves public health.
It is important to note that the cells have not been tested for performance under heat, air humidity or other outdoor loads, so that these panels require more development and research time before they are used on a scale.
The installation of solar modules at home is already one of the ultimate Home -Energy hacks and can reduce the costs of your electricity almost 0 US dollars -and perhaps even the monthly electricity bill in the past.

Solar also makes the use of other money -saving electrical devices such as heat pumps that are even cheaper. Mitsubishi can help you find the right, affordable heat pump for your home.
Perovskite-on-Silicon's solar modules will probably take time to become commercially sustainable. Therefore, it is always a good idea to start your clean energy trip with proven options such as roof solar.
“Our research offers critical technical solutions for the development of new self-organized mono-government materials and the further further development of the efficiency of silicon-perovskit tandem,” the team wrote.
This breakthrough in Solar could help promote clean energy and to accelerate the relocation to a low -carbon future for everyone.
