Here all the variances and the mean are computed from the intensity images in electrons unit which are obtained by multiplying the intensity images in digital units with γ.
TTI as electron pushing unit and ID as electron pulling unit were incorporated in the push pull types of conjugated polymers (PTTIID, PTTIID-3, PTTIID-5 and PTTIID-7).
Four novel tetrahydroquinoline dyes by inserting isophorone and/or thiophene moieties as π bridge between the electron donating unit of substituted tetrahydroquinoline and the electron withdrawing unit of cyano carboxylic acid have been synthesized and successfully applied to dye-sensitized solar cells.
Push-pull types of conjugated polymers (PTTICN, PTTICNR and PTTIFR) containing TTI as electron pushing unit and 2-pyriminecarbonitrile or 2-fluoropyrimidine as electron pulling unit were synthesized.
A new A D A small molecule, named DTB3TCz, with a weak electron donating unit (carbazole) as the core and a strong electron withdrawing unit (thiobarbituric acid) as the terminal acceptor, was designed and synthesized for organic solar cells.
Two regioisomeric π-conjugated terpolymers bearing carboxylated thiophene (CT) as electron accepting unit and thienothiophene (TT) and bithiophene (BT) as electron donating units were successfully synthesized for enhancing the performance of polymer solar cells (PSCs).
Small molecules, SM1 and SM2, with bithiophene-imide as the central electron deficient unit and bridged thiophene and terminal triphenyl amine as electron rich units, have been designed and synthesized.
PCPDTBT conjugated polymer, comprising two units "CPDT" (electron-donating unit) and "BT" (electron-accepting unit), has shown strong polymer/fullerene interactions suggesting effective photoinduced charge transfer [20, 34].
