제목 Indium Tin Oxide Free Semitransparent Organic Photovoltaic Cells using Ytterbium as N-type Buffer Layer on Transparent Cathode Electrodes
초록 We investigate Indium Tin Oxide (ITO) free semitransparent Organic Photovoltaic Cells (OPVs) with WO3/Ag/WO3 (W/A/W) layer as the transparent anode and Yb/BCP/Ag/WO3 (Y/B/A/W) layer as the transparent cathode. The both electrodes showed the low sheet resistance below 8.5 Ω/□ and observed the high transparency 90% (at λ=535nm). The semitransparent devices W/A/W/poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester(P3HT:PCBM)/Y/B/A/W recorded an average power conversion efficiency(PCE) of 2.2% estimated for 100 mW/cm2 air mass 1.5 global illumination. Through our experimentation, we analyzed the effects of high PCE on the device physics of organic solar cells via Secondary Ion Mass Spectrometry and Ultra-Violet Photoelectron Spectroscopy.
