摘要:	摘要： We reported the synthesis and characterization of two new BODIPY type dyes with fluorine‐bridged two chromophores, boron‐dipyrromethene (BDP) and boron‐diindomethene (BDI). Each of BODIPY dyes 7a and 7b has two strong absorption bands around 500 and 600 nm bearing high extinction coefficients (76,000 M‐1cm‐1 for 7a and 71,000 M‐1cm‐1 for 7b at 501 nm; 115,000 M‐1cm‐1 for 7a and 110,000 M‐1cm‐1 for 7b at 603 nm). For light harvesting enhancement of solar cell, we have fabricated bulk heterojunction photovoltaics with various weight percentages of 7a as dopant dye in P3HT:PCBM blends in attempting to improve power conversion efficiency of solar energy. Dual visible absorption BODIPY‐type dyes, 7a and 7b, have been synthesized and spectroscopically characterized. Dual visible absorption bands of 7a and 7b are intense (∼105 M‐1cm‐1) and sharp (full‐width‐of‐half‐intensity < 25 nm). BODIPY‐type dye 7a has been adopted as the light harvesting dopant in bulk heterojunction P3HT/PCBM organic photovoltaic (OPV). The performance of 7a‐doped P3HT/PCBM OPVs are analyzed in detail. 其他題名： Jnl Chinese Chemical Soc 出版者： Weinheim: WILEY-VCH Verlag 出版日期： 2012-03 出處： Journal of the Chinese Chemical Society (Taipei), 2012-03, Vol.59 (3), p.305-316 版權： Copyright © 2012 The Chemical Society Located in Taipei & Wiley‐VCH Verlag GmbH & Co.
