Researchers have succeeded in producing perovskite solar cells with a record-breaking efficiency of 23.2 percent. With the help of a so-called miracle cure, they managed to influence chemical reactions and at the same time increase the lifespan of the cells.
Perovskite solar cells (PSC) are considered a great hope in the solar industry. Because they promise high efficiency with low production costs. Researchers from the University of Surrey investigated as part of a current study the performance and stability of solar cells based on tin-lead perovskite and the hole transport layer material PEDOT:PSS.
This material is inexpensive and is therefore often used. However, it also reveals challenges in terms of stability and efficiency. The researchers made progress by reducing iodine formation processes that are responsible for performance degradation.
The reason: Iodine and its chemical byproducts cause structural damage and reduce the lifespan of solar cells. By using special additives such as thiocyanate, the scientists were able to improve the stability of the cells. This substance reduces the formation of harmful iodine, but has side effects under humid conditions, such as the formation of cyanide compounds.
Perovskite solar cells achieve new record efficiency
To overcome these weaknesses, the researchers developed a novel method. They used an iodine reducing agent called benzylhydrazine chloride (BHC). This additive prevents the formation of iodine and ensures greater cell efficiency.
As part of their study, the team achieved a record-breaking efficiency of 23.2 percent. This would represent a new frontier for the technology. The approach is also expected to increase the lifespan of the cells by around 66 percent under normal environmental conditions.
The researchers achieved these improvements without major structural changes to the solar cells. This shows how important chemical optimization is for the further development of the technology.
Further development of designs could make perovskite cells socially acceptable
Research shows that the combination of chemical additives and new design approaches can be crucial for the further development of perovskite solar cells. In the long term, the advances could help establish PSCs as a leading technology in the field of renewable energy.
However, the challenge remains to further increase stability under real conditions and enable commercial production. However, the results of the study lay an important foundation for the next generation of efficient and long-lasting solar cells.
