SOLAR CELLS GET A SPRING IN THEIR STEP: BREAKTHROUGH INTERFACE BOOSTS EFFICIENCY AND DURABILITY

In a groundbreaking discovery, a team of scientists from the Hong Kong University of Science and Technology (HKUST) has made a significant breakthrough in the field of solar energy. By developing a novel chiral-structured interface in perovskite solar cells, they have improved their efficiency and durability, paving the way for commercialization. This innovative design could revolutionize the solar industry by making perovskite solar panels more dependable in various weather conditions.

THE BREAKTHROUGH

Perovskite solar cells are a type of solar cell that uses inexpensive and simple-to-manufacture materials. However, one major barrier to their commercialization has been their stability under real-world conditions. The team led by Prof. Zhou Yuanyuan and Dr. Duan Tianwei addressed this issue by creating an unprecedented chiral-structured interface in PSCs.

The researchers inserted chiral-structured interlayers based on R-/S-methylbenzyl-ammonium between the perovskite absorber and electron transport layer to create a strong, elastic heterointerface. This design allows for enhanced reliability and power conversion efficiency, making it more suitable for commercialization. The team’s innovative approach has been published in the prestigious journal Science, with their research paper titled “Chiral-structured heterointerfaces enable durable perovskite solar cells”.

THE SCIENCE BEHIND THE BREAKTHROUGH

The concept of chirality is a fundamental aspect of chemistry and physics, referring to the ability of a molecule or object to be asymmetric. In the context of solar cells, chirality can play a crucial role in determining their efficiency and stability. By introducing chiral-structured interlayers into perovskite solar cells, the researchers aimed to create a more robust and reliable interface between the perovskite absorber and electron transport layer.

The team’s innovative design is based on the principle of “springiness”, which refers to the ability of an object or material to maintain its shape and stability even when subjected to stress or strain. By incorporating chiral-structured interlayers into PSCs, the researchers have effectively created a springy interface that can withstand various environmental conditions.

THE IMPACT

This breakthrough holds great promise for the future of solar energy. With the potential for enhanced reliability and power conversion efficiency, future perovskite solar panels could become even more dependable in various weather conditions, ensuring continuous electricity generation over extended periods. This is particularly significant considering the increasing demand for renewable energy sources.

In addition to its commercial implications, this breakthrough also has significant scientific and technological implications. The development of chiral-structured interfaces in PSCs opens up new avenues for research and innovation in the field of solar energy.
