Check Digit Verification of cas no

The CAS Registry Mumber 1160823-78-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,8,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1160823-78:
(9*1)+(8*1)+(7*6)+(6*0)+(5*8)+(4*2)+(3*3)+(2*7)+(1*8)=138
138 % 10 = 8

A facile strategy to enhance the fill factor of ternary blend solar cells by increasing charge carrier mobility

Lu, Kun,Fang, Jin,Zhu, Xiangwei,Yan, Han,Li, Denghua,Di, Chong'An,Yang, Yanlian,Wei, Zhixiang

, p. 1728 - 1735 (2013)

Two conjugated polymers based on benzo[1,2-b:4,5-b′]dithiophene (BDT) with triethylene glycol (TEG) and ethylhexyl side chains (abbreviated as PBDTT-TEG and PBDTT-EH, respectively) were designed and synthesized. A polymer field-effect transistor of PBDTT-TEG exhibited a charge carrier mobility nearly one order of magnitude higher than that of PBDTT-EH. Measurements on polymer solar cells (PSCs) based on polymer:[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) binary blends showed the PBDTT-TEG-based devices had higher short-circuit current density (Jsc) than PBDTT-EH. The effect of the incorporation of PBDTT-TEG into PBDTT-EH on the photovoltaic properties has been investigated by blending them together with different ratios. The optimization of the devices showed an obvious increase in fill factor (FF) values and an improvement in efficiency compared with their binary ones, which is ascribed to a higher charge mobility and higher crystallinity of PBDTT-TEG.

Comparison of thiophene- and selenophene-bridged donor-acceptor low band-gap copolymers used in bulk-heterojunction organic photovoltaics

Chen, Hung-Yang,Yeh, Shih-Chieh,Chen, Chao-Tsen,Chen, Chin-Ti

, p. 21549 - 21559 (2012)

We report a detailed comparison of absorption spectroscopy, electrochemistry, DFT calculations, field-effect charge mobility, as well as organic photovoltaic characteristics between thiophene- and selenophene-bridged donor-acceptor low-band-gap copolymers. In these copolymers, a significant reduction of the band-gap energy was observed for selenophene-bridged copolymers by UV-visible absorption spectroscopy and cyclic voltammetry. Field-effect charge mobility studies reveal that the enhanced hole mobility of the selenophene-bridged copolymers hinges on the solubilising alkyl side chain of the copolymers. Both cyclic voltammetry experiments and theoretical calculations showed that the decreased band-gap energy is mainly due to the lowering of the LUMO energy level, and the raising of the HOMO energy level is just a secondary cause. These results are reflected in a significant increase of the short circuit current density (JSC) but a slight decrease of the open circuit voltage (VOC) of their bulk-heterojunction organic photovoltaics (BHJ OPVs), of which the electron donor materials are a selenophene-bridged donor-acceptor copolymer: poly{9-dodecyl-9H-carbazole-alt-5, 6-bis(dodecyloxy)-4,7-di(selenophen-2-yl) benzo[c][1,2,5]-thiadiazole} (pCzSe) or poly{4,8-bis(2-ethylhexyloxy)benzo[1,2-b;4,5-b′]dithiophene-alt-5,6- bis(dodecyloxy)-4,7-di(selenophen-2-yl)benzo[c][1,2,5]-thiadiazole} (pBDTSe), or a thiophene-bridged donor-acceptor copolymer: poly{9-dodecyl-9H-carbazole-alt- 5,6-bis(dodecyloxy)-4,7-di(thiophen-2-yl)benzo[c][1,2,5]-thiadiazole} (pCzS) or poly{4,8-bis(2-ethylhexyloxy)benzo[1,2-b;4,5-b′]dithiophene-alt-5, 6-bis(dodecyloxy)-4,7-di(thiophen-2-yl)benzo[c][1,2,5]-thiadiazole} (pBDTS); the electron acceptor material is [6,6]-phenyl-C61-butyric acid methyl ester (PCBM). Judging from our device data, the potential Se-Se interactions of the selenophene-bridged donor-acceptor copolymers, which is presumably beneficial for the fill factor (FF) of BHJ OPVs, is rather susceptible to the device fabrication conditions.

A novel D2-A-D1-A-D2-type donor–acceptor conjugated small molecule based on a benzo[1,2-b:4,5-b″]dithiophene core for solution processed organic photovoltaic cells

Yu, Junting,Zhu, Weiguo,Tan, Hua,Peng, Qing

, p. 254 - 259 (2017/02/18)

A novel D2-A-D1-A-D2-type donor–acceptor conjugated small molecule (DTPA-Q-BDT-Q-DTPA) with a benzo[1,2-b:4,5-b′]dithiophene (BDT) core and two D2-A arms has been synthesized and employed as electron donor for organic solar cells. Solution-processed organic photovoltaic (OPV) devices were fabricated with a configuration of ITO/PEDOT:PSS/DTPA-Q-BDT-Q-DTPA:[6,6]-phenyl-C61-butyric acid methyl ester (PC61BM)/LiF/Al. A power conversion efficiency (PCE) of 1.22% with an open-circuit voltage (VOC) of 0.64?V, a short-circuit current (JSC) of 6.10?mA?cm?2, and a fill factor (FF) of 31.0% was achieved. The PCE is 2.9 times higher than that in the other devices using D2-A-type small molecule TPA-Q-TPA as donor.
