李代宇博士在2018年1月22日-1月26日参加在日本冲绳举办的能源科学与技术国际交流研讨会（ISEST 2018），并携带本课题组海报参加海报展示。ISEST汇聚钙钛矿材料领域世界一流学者，分享该领域最新最前沿的科技成果。他的海报题为“使用高导电性碳电极的印刷介观钙钛矿太阳能电池”，摘要如下：
Tomeet the demand of lowcost, high efficient and stablephotovoltaic technology, printable mesoscopic perovskite solar cells based oncarbon electrode (MPSCs) have been developed. High electrical conductivity ofcarbon electrode is a key factor to achieve high performance of devices. Highlyconductive carbon electrode can decrease the series resistance of device, thusimprove the photovoltaic parameters of short-circuit current (JSC) and fill factor (FF). Herein, we achieved a highlyconductive, low-temperature and perovskite-compatible carbon electrode andanother high work function carbon electrode. Both have better conductivity thanour previous benchmark carbon films. By introducing these two kinds of carbonelectrode into MPSCs, we achieved high PCEs of 14.04% and 13.6%, respectively.
