技術名稱: 可印式tandem solar cell 材料與元件開發技術

技術簡介

本計畫在關鍵主動層材料開發以及tandem cell元件技術均有重大的技術提昇:在材料部分本計畫合成開發一系列兼具廣波域、高吸收能力以及高載子遷移率等優異性質的新型有機半導體材料,其中材料光吸收範圍可延伸至near IR部分,單接面元件效率均可高於4.0% (AM1.5G)以上;而本團隊進一步結合所開發之上述有機半導體材料,成功建立以串連方式連結的all solution tandem cell元件技術,具有高Voc特性(Voc>1.3 Volt),目前此新型有機高分子tandem cell的最佳光電轉換效率可達4.6% (AM1.5G)。對於所開發的多接面元件(tandem cell),包含上下層互補吸收之主動層材料與中間電極(TiOx)合成技術的開發,以及成功建立的multi-junction元件的製作技術,在國外研討會上被證明是除了Nobel 得主Professor Heeger的團隊外,唯一一個成功以all solution process製作有機tandem solar cell的團隊,具有與國際同步的領先技術。目前tandem元件效率已達4.6%,下年度在結合元件模擬之parameters之後,此種結合本團隊自有材料技術的tandem cell有機會上看8%之光電轉換效率。

Abstract

In this project, the MCL team have 2 major breakthrough on key active material development as well as tandem cell device advancing. The former includes novel material design and synthesis allowing them to possess balanced properties such as broad absorption, high absorptivity, and high carrier mobility. The material absorption spectrum can be broadened to near IR regime and single junction cell on a series of these material can achieve over 4% power conversion efficiency. While adopting these proprietary material into tandem cell design, this team overcome the melt-down difficulty often encountered with multi-layer films stacking by solution process. It has been evident that we are the only team in the world besides the Nobel Laureat, Dr. Allen Heeger’s group, that are successfully making TiOx as the intermediate layer to compile tandem cell with all solution process. This advancement put our team in one of the world’s leading position in solution tandem cell technology.
