Third-generation photo voltaic cell expertise is seeing speedy growth at The Hong Kong Polytechnic College. Researchers at PolyU have recognized breakthrough approaches in perovskite/silicon tandem photo voltaic cells, concentrating on advances in effectivity, stability, and scalability. Their efficiency evaluation and suggestions goal to drive power conversion effectivity from round 34 % to 40 %. The group is accelerating commercialization by fostering collaborations between trade, academia, and analysis, supporting carbon neutrality plans and the adoption of renewable power for innovation together with synthetic intelligence.
The workforce, led by Prof. Li Gang and Prof. Yang Guang of PolyU’s Division of Electrical and Digital Engineering, critically reviewed technical challenges for tandem photo voltaic cells. Their paper, printed in Nature Photonics, highlights instability points underneath environmental stresses like moisture, oxygen, ultraviolet mild, and temperature fluctuations. Scaling up from small laboratory units to business modules requires overcoming obstacles in uniformity, defect administration, and large-scale fabrication.
“Whereas lab-scale units have proven spectacular effectivity development, additional efforts are wanted to enhance their reliability, together with minimising effectivity losses from small-area units to large-area modules,” stated Prof. Li Gang. “Particular focus also needs to be given to making sure that the manufacturability of supplies and strategies aligns with industrial requirements.”
Prof. Yang Guang and colleagues advocate intensive stability testing aligned to Worldwide Electrotechnical Fee requirements in an effort to higher measure product lifetime and business viability. Though preliminary outside exams are underneath manner, dependable long-term outcomes are nonetheless restricted.
Financial and regulatory points come up from the usage of uncommon components and lead in perovskite supplies. The workforce requires the event of safer options and for environment friendly recycling or containment methods to make large-scale commercialization each technically and environmentally possible.
