Tandem solar cells are currently stirring the solar industry. Because of their different layers and materials, they set new standards. A current model now promises an efficiency of over 33 percent.
Solar systems are considered one of the most important technologies for a sustainable future. But conventional solar cells are reaching physical limits when it comes to efficiency and energy conversion. So-called tandem solar cells remedy the situation. A new model recently broke several efficiency records and could significantly advance the energy transition.
Normal solar cells mostly consist of silicon, which absorbs sunlight and converted into electricity. However, silicon can only effectively use certain parts of light, which means that the maximum efficiency is almost 29 percent. In practice, today’s modules reach around 24 percent. To overcome this limit, scientists are increasingly relying on tandem solar cells.
Tandem solar cells: combination of silicon and perovskit
Tandem solar cells combine two different materials: silicon for the longer red shares of the sunlight and perovskit, which particularly uses the high-energy blue shares. A layer technology enables higher energy yield.
The Chinese company Jinkosolar recently set up a new world record with its tandem solar cells. The modules achieved an efficiency of 33.84 percent. The company thus exceeded its own previous record of 33.24 percent.
According to company, the progress is said to have succeeded through improved connection technologies between the two layers and an optimization of the Perowskit crystals.
German companies also mix the market
Successes are also recorded in Germany: the company Q cells developed a tandem solar cell that should be suitable for industrial mass production with an efficiency of 28.6 percent. In contrast to laboratory tests, in which only tiny cells are tested, the company has apparently developed a marketable module.
Despite the promising developments, there are still a few hurdles to overcome. The Perowskit is currently not stable enough for long -term use, as it is sensitive to moisture and oxygen.
In addition, the manufacturing costs for tandem solar cells are currently even higher than with conventional silica modules. Nevertheless, investors rely on technology. With further advances, tandem solar cells could soon be used on house roofs and in solar power plants and make a decisive contribution to sustainable energy supply.

As a Tech Industry expert, I am extremely excited about the breakthrough in tandem solar cell technology that has recently been achieved. The fact that these new tandem solar cells have broken records in terms of efficiency is a significant milestone for the industry.
This advancement in tandem solar cells is particularly exciting because it has the potential to greatly increase the efficiency of solar panels, ultimately making solar energy more cost-effective and accessible to a wider range of consumers. This could have a major impact on the transition to renewable energy sources and help to combat climate change.
I am eager to see how this breakthrough in tandem solar cell technology will be further developed and commercialized in the coming years. It is innovations like this that will continue to drive the growth and success of the renewable energy sector, and I am optimistic about the positive impact it will have on our environment and society as a whole.
