中科院院士李永舫在湖南部分中學作科普報告

文章來源:亞熱帶農業生態研究所   發布時間:2019-04-08  【字號:     】  

  4月2日至4日,中國科學院院士、中國科學院化學研究所有機固體重點實驗室研究員李永舫在湖南婁底三中、漣源一中、邵東一中、邵陽二中分別舉行科普報告會。四校近4000余名師生參加。

  李永舫以“天道酬勤——我的人生感悟兼談聚合物太陽電池最新研究進展”為主題,深入淺出介紹了他在導電聚合物電化學等領域的科研成果,并用他自己拼搏奮斗的親身經歷和個人感悟勉勵青少年學生努力學習、奮發向上,給大家帶來了一場別開生面的科普報告會。

  李永舫為師生們介紹了有機太陽電池的發展歷程和最新成果。有機太陽電池具有成本低、結構簡單、輕便柔韌、半透明的優點,在未來擁有廣闊的應用前景。李永舫從上世紀八十年代導電高分子應用和光電轉化效率的突破談起,從吸收互補、電荷載流子遷移率、電子能級匹配、理想給受體網絡結構的形成等幾個角度說明了高效太陽電池材料所必備的基本性質。他提出的分子設計策略,即以共軛聚合物為給體、以n-型有機半導體(如富勒烯)為受體的材料體系,大大提高了有機太陽電池的光電轉化效率。現在,由他領導的課題組已經把電池的光電轉化效率提高到了12.5%,后期將致力于提高電池材料的穩定性、降低制造成本,實現實際應用。

  李永舫1948年出生于重慶,經歷了戰火年代的動蕩,度過了饑荒的年代,在時代變革中克服重重困難,把握發展機遇并通過自身的努力,最終獲得了令人矚目的成就。李永舫根據自己的親身經歷,在成長成才方面和廣大師生分享了自己的人生感悟,教導學生首先要“熱愛學習”,興趣是最好的導師,無論生活是苦是樂,要不懈努力永不止步。第二,要秉持“天道酬勤”的人生觀念,牢記“認真”是助人成功的秘訣。第三,必須“待人以誠”,多替別人著想,如此才能贏得別人的尊重。第四,要保有一顆“順其自然”的寬容之心,在有所追求的前提下,對待成敗得失更需一分為二的辯證眼光。最后,他總結了取得成功的八字箴言,即“熱愛+用心+努力+認真”。

  此次系列科普報告屬于中國科學院大學“春分工程·青少年科普專項行動”,旨在倡導科學理念,培養科學思維,增強實踐創新能力,有效提升青少年科學素質。報告既使同學們領悟了“天道酬勤”的人生哲理,又讓同學們再一次接觸到了科學研究領域的最前沿成果,使同學們增長了學識,啟發了思路,增強了科技報國情懷和責任擔當意識,是一次科學與人文的精神盛宴。

  國科大湖南招生組共同組長王新洪、副組長譚紅軍和組員卿來云陪同講座。譚紅軍和卿來云就國科大學校簡介、本科招生等分別給上述四校理科重點實驗班學生進行了詳細介紹。據悉,在本科招生上,國科大2019年在湖南計劃招生37名理科(本科)學生,其中綜合評價24名、統招8名、貧困專項計劃5名。
