讲座摘要:

Minimizing energy loss is a key aspect to transcend the current limitations on the performance of organic and perovskite photovoltaics (OPV & PVSC). Our recent study reveals that the fully-fused rigid molecular acceptors are not only intrinsically highly luminescent but also meets the criteria in achieving intrinsically radiative recombination within the blend, which is a key step in moving towards new OPV materials and selection criteria if they are to approach the theoretical efficiency limits. In addition to the development of OPV, composition and interface engineering have been explored to dramatically improve the efficiency and long-term operational stability of the PVSC. Moreover, a very innovative approach has also been developed to combine both efficient charge extraction and the ability to trap decomposed Pb-containing perovskites into one material to address the most challenging environmental contamination issue for the commercialization of PVSCs.

This talk will be divided into three parts:

1. Advances in developing novel non-fullerene acceptors to achieve record-high certified efficiency (17.5%) with low photovoltage (Voc) loss;

2. Progress of achieving the highest efficiency (23.1%) in inverted perovskite solar cells (PVSCs) through smart engineering of the interfaces;

3. Demonstration of the simultaneous achievement of high PCE (>22%), excellent operational stability (85°C at MPP for 1000h under 1 Sun illumination), and the ability to capture degraded Pb-containing by-products by employing 2D metal-organic frameworks (2D-MOF) as a charge extraction layer in PVSCs.    


嘉宾简介:

Professor Alex K-Y. Jen is the Provost and Chair Professor of Chemistry and Materials Science of the City University of Hong Kong. He is a distinguished researcher with more than 900 publications, 65,000 citations, and an H-index of 127. He is also a co-inventor for 63 patents and invention disclosures. His interdisciplinary research covers organic/hybrid functional materials and devices for photonics, energy, sensors, and nanomedicine.

For his pioneering contributions in organic photonics and electronics, Professor Jen was elected as an Academician by both the European Academy of Sciences and the Washington State Academy of Sciences. He is also a Fellow of several prestigious professional societies including AAAS, MRS, ACS, PMSE, OSA, SPIE. He was named by the Times Higher Education (THE) as one of the “Top 10 university researchers in Perovskite Solar Cell Research” from 2014 to 2017. In addition, he was recognized by Thomson Reuters as one of the World’s Most Influential Scientific Minds of 2015-16 and as a Highly Cited researcher in materials science from 2014-2020. He has also demonstrated strong capability in technology transfer, and was the founder of the Institute of Advanced Materials for Energy (i-AME) of the University of Washington.
