A analysis workforce from the Faculty of Engineering at The Hong Kong College of Science and Expertise (HKUST) has developed a pioneering multiscale bio-inspired technique to enhance the long-term stability and environmental resilience of perovskite photo voltaic cells. Collaborating with main establishments within the US and Switzerland, the workforce has adopted nature-based design ideas to beat key limitations to commercialization.
Perovskite photo voltaic cells are valued for his or her low-cost, solution-based manufacturing, however their widespread deployment is hindered by poor interfacial adhesion, restricted mechanical robustness, and vulnerability to moisture, UV radiation, and warmth. These challenges come up at scales starting from the molecular to the machine degree.
Led by Affiliate Professor ZHOU Yuanyuan from HKUST’s Division of Chemical and Organic Engineering and the Vitality Institute, the researchers suggest a scientific redesign of perovskite photo voltaic cells impressed by nature’s hierarchical constructions. For instance, plant leaves and bug exoskeletons supply fashions for thermal regulation, sturdiness, and environment friendly mild absorption.
The technique consists of three design ranges: molecular, the place bio-inspired interactions information crystal formation and restrict degradation; microscale, the place self-healing and reinforcement mechanisms are carried out; and machine degree, the place organic analogs like moth eyes and beetle shells inform useful structure for mild and thermal administration.
“Nature supplies an considerable reservoir of design options to assist us construct photo voltaic supplies that may thrive in real-world situations,” mentioned Prof. Zhou. “We have already translated a few of these methods into artificial vitality units.”
The analysis builds on two latest advances by Prof. Zhou’s group. The primary entails a chiral interface design utilizing R-/S-methylbenzylammonium, which mimics organic springs to reinforce mechanical durability-this research appeared in Science. The second includes a laminated, multi-layer interfacial construction that mimics organic membranes to suppress defects and enhance vitality alignment-this was revealed in Nature Synthesis.
The workforce emphasizes sustainability by specializing in low-toxicity parts and designs appropriate with round economies. Future work will prioritize deciding on bio-derived molecules for improved crystal management, growing stress-triggered self-healing options, and optimizing multi-functional encapsulation for longevity and effectivity.
Dr. DUAN Tianwei, the research’s first creator and a Analysis Assistant Professor at HKUST, remarked, “This isn’t nearly new supplies; it represents a novel strategy to photo voltaic expertise, impressed by nature itself. By integrating bio-inspired constructions, capabilities, and sustainability, we’re excited concerning the new chapter unfolding in photo voltaic vitality.”
