Researchers In China Develop New Revolutionary Solar Cell, With A Conversion Efficiency Of 26.4%, An Unprecedented Milestone That Promises To Transform The Solar Energy Sector And Drive Technological Advancements In The Segment.
An international team led by researchers from the Institute of Chemistry at the Chinese Academy of Sciences has developed a new type of high-efficiency solar cell for clean energy generation. The new solar cell from China, a tandem perovskite-organic, can achieve a photoelectric conversion of 26.4%, the highest efficiency for these solar cells to date, according to Li Yongfang, an academic and researcher at the institute.
Understand The Importance Of The New Solar Cell From China For The Clean Energy Market
The perovskite solar cells and organic solar cells represent the next generation of solar cells. Compared to the widely used crystalline silicon solar cell, this new solar cell from China for clean energy generation offers advantages like ease of manufacturing, lightweight, and the ability to be applied in flexible devices.
These features represent significant application prospects in areas such as portable clean energy, building-integrated photovoltaics, and indoor photovoltaics.

The new solar cell from China uses wide-bandgap perovskite materials to absorb short-wavelength sunlight and a narrow-bandgap organic active layer to absorb long-wavelength sunlight in the near-infrared, Li states. He added that this combination significantly expands the usable solar spectrum and effectively increases the clean energy conversion efficiency of the device.
Clean Energy Market Significantly Expands And Develops New Technologies
In addition to this new solar cell from China, called the tandem perovskite-organic, American scientists are developing a cell capable of converting direct sunlight into energy with an efficiency of 44.5%. This potentially makes it the most efficient silicon solar cell in the world, at least among those currently available on the market.
Current models only convert electricity with an efficiency of approximately 26%, at most. For comparison, the solar cell with the highest efficiency in Brazil has an efficiency of 17.3%.
The impressive product developed now at the George Washington University uses concentrated photovoltaic (CPV) panels that employ lenses to focus sunlight onto tiny solar cells. The new solar cell acts like a sieve for sunlight, with specialized materials in each layer capable of absorbing energy.
According to Dr. Matthew Lumb, the lead author of the study and research scientist at GW School of Engineering and Applied Science, the new device is capable of unlocking the clean energy stored in long-lasting photons, lost in conventional solar cells, and thus provides a pathway to the realization of the ultimate multi-junction solar cell.
To achieve this, the product uses materials typically found in applications for lasers and infrared photodetectors.
New Oxford Perovskite Solar Cell
One-tenth the thickness of a human hair is the thickness of the new perovskite cells being tested in the United Kingdom. Their creators believe that one day they will cover all types of buildings and objects, eliminating the need for conventional solar panels.
In short, a team of physicists at the University of Oxford has developed an ultrathin film that can convert sunlight into an impressive amount of clean energy.
The perovskite-based material is so thin and flexible that it can be applied as a coating on virtually any building or everyday object, such as backpacks, cars, and cell phones.
At just over one micron thick, the new perovskite cell developed by Shuaifeng Hu and colleagues from the Department of Physics at Oxford is 150 times thinner than a silicon wafer.
To make this possible, they invented a new technique that stacks multiple layers of light-absorbing material in a single photovoltaic cell. In this way, each cell captures a wider range of the light spectrum.
