Tin-perovskit solar cells are not only non-toxic, but also more potentially stable than leading perovsky solar cells. Researchers in Berlin have now significantly increased their efficiency.

Perovskit solar cells are considered hopefuls in the solar industry. Although they are efficient and cheap, they have a decisive disadvantage: a large part of the powerful variants contains lead.

That doesn’t necessarily make you sustainable. The alternative: tin-perovskit solar cells. Not only are they non -toxic, but also more potentially stable.

Tin-Perowskit solar cells: more sustainability without lead

Due to their special electro-optical properties, tin-perovskit solar cells are particularly suitable for tandem and triple solar cells. Nevertheless, they are still far from reaching the high levels of efficiency of leading Perowskites.

Scientists of the Helmholtz Center Berlin (HZB) with their research, exactly in this area, could achieve a breakthrough. In cooperation with partners in Lithuania, the team identified chemical compounds, which of themselves form a molecular layer that fits very well with the grid structure of tin-perovskites.

In this so-called monolage, tin-perovskit with excellent optoelectronic quality can be growed up. In short: efficiency improves significantly.

Targeted design: How does the technology work?

There are self-organized monosherms (Sams) behind the increase in efficiency. “In current tin-perovskit solar cells, the lowest contact layer with Pedot: PSS is made,” explains the Helmholtz Center. This is not only an elaborate process, but also leads to losses. However, the pedot: PSS layer can be replaced by Sams in Blebeperovskites.

So far, experiments with Sams, based on Zinnperowskiten, have provided worse results than with Pedot: PSS. With the help of the sulfur-containing functional group Phenothiazin (TH-2EPT), however, the scientists now found a way to minimize energy losses and noticeably increase the efficiency of lead-free cells.

“We have shown that the performance of Zinn-Perowskit-Photovoltaic can be significantly improved by targeted molecular design,” said Artem Musiienko, head of the group robotic optoelectronic materials and photovoltaic engineering at the HZB.

The new Zinn-Persovskit solar cells with TH-2EPT achieve an efficiency of 8.2 percent. These results lay the foundation for further improvements in the tin-perovskit border areas and pave the way for the development of tandem solar cells from pure tin perovsky.

Applications of tin-perovskit solar cells

Perowsian Design a fabric class With a special crystal structure that can be excellently absorbed and efficiently convert into electricity. Perowskit solar cells are thin, flexible and can be produced inexpensively in the low-temperature process, also as foils, on glass or plastic.

This opens up a variety of uses. They are suitable for lightweight buildings, mobile devices, vehicle roofs or portable solar charging devices.

They can also be integrated into building facades and windows. Due to the lack of lead and low energy expenditure, you could also become a more sustainable option for large photovoltaic areas.

Tin-perovskit solar cells still need improvements in efficiency. Nevertheless, they already combine environmentally friendliness and constant progress in research.

The improved efficiency of Zinn-Persovskit solar cells means that they can now convert a higher percentage of sunlight into electricity, making them a more cost-effective and viable option for widespread adoption. This is particularly important as we strive to reduce our reliance on fossil fuels and combat climate change.

I look forward to seeing how this technology continues to evolve and be integrated into various applications, potentially revolutionizing the way we harness solar energy. It is advancements like these that will drive the growth of renewable energy sources and help us build a greener and more sustainable world.
