PolyU researchers achieve record 19.31% efficiency with organic solar cells

Researchers from The Hong Kong Polytechnic University (PolyU) have achieved a breakthrough power-conversion efficiency (PCE) of 19.31% with organic solar cells (OSCs), also known as polymer solar cells. This remarkable binary OSC efficiency will help enhance applications of these advanced solar energy devices. The PCE, a measure of the power generated from a given solar irradiation, is considered a significant benchmark for the performance of photovoltaics (PVs), or solar panels, in power generation. The improved efficiency of over 19% that was achieved by the PolyU researchers constitutes a record for binary OSCs, which have one donor and one acceptor in the photo-active layer. Led by Prof. LI Gang, Chair Professor of Energy Conversion Technology and Sir Sze-Yuen Chung Endowed Professor in Renewable Energy at PolyU, the research team invented a novel OSC morphology-regulating technique by using 1,3,5-trichlorobenzene as a crystallisation regulator. This new technique boosts OSC efficiency and stability. The team developed a non-monotonic intermediated state manipulation (ISM) strategy to manipulate the bulk-heterojunction (BHJ) OSC morphology and simultaneously optimise the crystallisation dynamics and energy loss of non-fullerene OSCs. Unlike the strategy of using traditional solvent additives, which is based on excessive molecular aggregation in films, the ISM strategy promotes the formation of more ordered molecular stacking and favourable molecular aggregation. As a result, the PCE was considerably increased and the undesirable non-radiative recombination loss was reduced. Notably, non-radiative recombination lowers the light generation efficiency and increases the heat loss. The research team’s findings are described in the study “19.3% Binary Organic Solar Cell and Low Non-Radiative Recombination Enabled by Non-Monotonic Intermediate State Transition” published in Nature Communications . The conversion of solar energy to electricity is an essential technology for achieving a sustainable environment. Although OSCs are promising devices that harness solar energy cost-effectively, their efficiency must be improved if they are to be used widely in practical applications. Prof. Li said, “Challenges in research came from the existing additive-based benchmark morphology control methods, which suffer from non-radiative recombination loss, thus lowering the open-circuit voltage due to excessive aggregation.” The research team took about two years to devise a non-monotonic ISM strategy for increasing the OSC efficiency and lowering the non-radiative recombination loss. The publication of the study promises to galvanise OSC research. Prof. Li said, “The new finding will make OSC research an exciting field, and this will likely create tremendous opportunities in applications like portable electronics and building-integrated PVs.” The new door will open when low cost single-junction OSCs can achieve a PCE of over 20%, along with more stable performance and other unique advantages such as flexibility, transparency, stretchability, low weight and tuneable colour. Prof. Li has been recognised as a Highly Cited Researcher 9 years in a row since 2014, which testifies to his significant impact on global research. His pioneering contributions to research on polymer solar cells since 2005 have brought sustainable influence on printable solar energy development with global recognition. Prof. Li said, “The latest study shows a record low non-radiative recombination loss of 0.168 eV in a binary OSC with a PCE of over 19%. This is a very encouraging result for the long-standing research on OSCs that I have conducted over the past two decades. We have already achieved better OSC efficiency, and this will subsequently help accelerate the applications of solar energy.” ***END***

PolyU and CUHK jointly develop ABarginase, the first-in-class drug for multiple obesity-related metabolic diseases

Researchers from The Hong Kong Polytechnic University (PolyU) and The Chinese University of Hong Kong (CUHK) have jointly made a groundbreaking drug discovery in treating multiple metabolic diseases related to obesity and insulin resistance like diabetes and fatty liver disease. The new drug, ABarginase, opens a new path for safe, long-lasting cures to multiple obesity related diseases simultaneously through an ingenious treatment mechanism – arginine starvation. Currently, patients often have to take multiple medications for these inter-related diseases, and are hence more prone to the potential risks of polypharmacy. ABarginase shows promise for the effective treatment of multiple metabolic diseases including prediabetes, type 2 diabetes and nonalcoholic fatty liver disease. The fabrication process of ABarginase is inexpensive and highly efficient, making it affordable and widely adoptable for clinical applications. The research is led by Prof. Thomas LEUNG Yun-chung, Professor of the Department of Applied Biology and Chemical Technology and Lo Ka Chung Charitable Foundation Professor in Pharmaceutical Sciences of PolyU, and Prof. Alisa SHUM Sau-wun, Associate Professor, School of Biomedical Sciences of the Faculty of Medicine of CUHK. Obesity is not just about being fat. It is associated with many chronic diseases, such as diabetes, nonalcoholic fatty liver disease, heart disease, hypertension and cancer. The PolyU-CUHK research team discovered that a low level of arginine (a semi-essential amino acid) in the blood can suppress fat synthesis, promote fat breakdown and sensitise cells to insulin. Native arginase can break down arginine, but it has a short circulatory half-life of less than 30 minutes. Prof. Thomas Leung said, “By using an advanced fusion protein strategy, our research team developed a long-lasting recombinant human arginase, ABarginase, that contains an albumin-binding domain, which enables it to bind with the stable and abundant albumin in the blood stream to extend its half-life by about 200 folds. ABarginase exhibits strong catabolic activity and it would only require one dose of ABarginase a week to maintain circulating arginine at low levels to achieve arginine starvation.” In preclinical studies, diet-induced obese mice were injected with ABarginase once a week, while control mice were injected with saline. Researchers found that within eight weeks of treatment with ABarginase, the treatment group’s body weight, fat mass, fatty liver and characteristic features of diabetes such as high blood glucose, insulin resistance and glucose intolerance were entirely reversed. Prof. Alisa Shum said, “The promising results show that ABarginase has great potential in safely and effectively treating multiple metabolic diseases related to obesity, insulin resistance, diabetes, and most importantly nonalcoholic fatty liver disease, which has no FDA-approved drug so far. We may have found the one drug that can cure them all.” Patent applications for this invention were filed in multiple countries. The research team is now scaling up the production for manufacturing ABarginase at Good Manufacturing Practices (GMP) grade in preparation for conducting clinical trials. Prof. Leung and Prof. Shum further added, “As scientists, we dream of building a better world. The successful development of ABarginase is an important step towards realising our dream.” In an affirmation of its potential benefit to patients and positive impact on global health, as well as a testament to the research excellence of inter-university collaboration, ABarginase recently won one of the two prestigious Grand Prizes awarded to Hong Kong in this year’s International Exhibition of Inventions Geneva – the International Federation of Inventors’ Associations (IFIA) Best Invention Award. Obesity is generally recognised as a global health problem. According to the latest data of the World Health Organization, more than 1.9 billion adults were overweight and over 650 million adults were obese in 2016, accounting for 39% and 13% of the world’s adult population. While in Hong Kong, about one in two adults are considered to be overweight or obese. The joint research project is supported by the Lo Ka Chung Charitable Foundation Limited, the Health and Medical Research Fund of the Health Bureau and the State Key Laboratory of Chemical Biology and Drug Discovery of PolyU.   ***END***
