Impact of Backbone fluorination on -conjugated polymers in organic photovoltaic devices: a review

Leclerc, Nicolas; Chávez, Patricia; Ibraikulov, Olzhas A.; Heiser, Thomas; Lévêque, Patrick (Polymers, 2016-01-12)

Solution-processed bulk heterojunction solar cells have experienced a remarkable acceleration in performances in the last two decades, reaching power conversion efficiencies above 10%. This impressive progress is the ...
Using pyridal[2,1,3]thiadiazole as an acceptor unit in a low band-gap copolymer for photovoltaic applications

Ibraikulov, Olzhas A.; Bechara, Rony; Chavez, Patricia; Bulut, Ibrahim; Tastanbekov, Dias; Leclerc, Nicolas; Hebraud, Anne; Heinrich, Benoît; Berson, Solenn; Lemaitre, Noëlla; Chochos, Christos L.; Lévêque, Patrick; Heiser, Thomas (Organic Electronics, 2015-08-01)

Abstract In this report, we explore the optoelectronic properties of a low band-gap copolymer based on the alternation of electron rich (thiophene and thienothiophene units) and electron deficient units (pyridal[2,1,3]thiadiazole ...
