Polymer solar cells (PSCs) are emerging as promising alternatives to silicon-based solar cells [1] thanks to light weight, mechanical flexibility, processability and low costs. One of the common polymers used in PSCs are 3-alkyl substituted polythiophenes, but a low band gap alternative is needed in order to reach better cell performances [2]. Copolymers bearing thienothiophene (TT) and benzodithiophene (BDT) alternating units are widely studied as donor material in Bulk Heterojunction Cells [3]. In this poster communication we report on the synthesis and spectroscopic electrochemical, photovoltaic characterization of two thiophene based copolymers bearing thienyl substituted-BDT units alternating with bithiophene and TT-units respectively.

Abstract
Polymer solar cells (PSCs) are emerging as promising alternatives to silicon-based solar cells [1] thanks to light weight, mechanical flexibility, processability and low costs. One of the common polymers used in PSCs are 3-alkyl substituted polythiophenes, but a low band gap alternative is needed in order to reach better cell performances [2]. Copolymers bearing thienothiophene (TT) and benzodithiophene (BDT) alternating units are widely studied as donor material in Bulk Heterojunction Cells [3]. In this poster communication we report on the synthesis and spectroscopic electrochemical, photovoltaic characterization of two thiophene based copolymers bearing thienyl substituted-BDT units alternating with bithiophene and TT-units respectively.
