Abstract: The present teachings relate to hybrid organic-inorganic perovskite solar cells including a hole-transport layer in contact with the perovskite light-absorbing layer, where the hole-transport layer (HTL) is a pristine (undoped) polymer. More specifically, the HTL comprises a copolymer including a benzo[1,2-d;4,5-d?]bistriazole-containing repeating unit and a benzo[1,2-b:4,5-b?]dithiophene-containing repeating unit.

Abstract: The system for detecting volatile organic compounds (VOCs) of this present invention comprises a detecting material made by blending a nano-material and a conductive polymer. The system for detecting VOCs presents the property of high sensitivity, high sensing accuracy, quick response, and real-time VOC detecting, and is demonstrated in the present work for commercialization usage. The system for detecting VOCs can be easily operated to detect VOC without electronic detecting method, and hence this invention can reduce a lot of operation energy and procedure. Furthermore, when adding inorganic nanoparticles, the area of VOC exposure of this invention is increased and the molecular morphology variation of the detecting material is enhanced, and hence the detecting activity of the system for detecting VOCs is improved.
