Effect of molecular weight on the photovoltaic performance of a low band gap copolymer blended with ICBA

Ibraikulov, O.; Bechara, R.; Leveque, P.; Leclerc, N.; Koishiyev, G.; Heiser, T. (Nazarbayev University, 2013)

In this work we fabricated solar cells by combining ICBA as electron acceptor material with various weight fractions of a low band gap electron donor copolymer based on 2,1,3-benzothiadiazole, thiophene and thieno[3,2-b]thiophene ...
Polymeric materials as photovoltaic materials for solar cells

Tastanbekov, D.; Ibraikulov, O.; Koishiyev, G.; Chavez-Vasquez, P.; Chochos, C.; Leclerc, N.; Bechara, R.; Lévêque, P.; Heiser, T. (Nazarbayev University, 2013)

Investigation revealed that alkyl chains in beta-position (fourth position of thiophene rings) lead to better pi-electron delocalisation due to enchanced planarity, because such position avoids rotational hinderance. Also, ...
