General description

1,3-Dibromo-5-(2-ethylhexyl)-4H-thieno[3,4-c]pyrrole-4,6(5H)-dione is a thienopyrrolodione (TPD) based electron acceptor material (n-type semiconductor) which is used widely for organic photovoltaic (OPV) applications. They have very powerful electron withdrawing capability. TPD based conjugated polymers have exhibited a Power Conversion Efficiency (PCE) of as high as 7.3% in bulk heterojunction polymer solar cells.

Application

  • This monomer is used in the synthesis of low band gap polymers for numerous OPV devices including bulk heterojunction solar cells.
  • Used as an electron acceptor material (n-type semiconductor) in Polymer Solar Cells.

Features and Benefits

High electron withdrawing capability, deeper HUMO levels leading to high Voc.

Two small molecules named BT-TPD and TBDT-TTPD with a thieno[3,4-c]pyrrole-4,6-dione (TPD) unit were designed and synthesized for solution-processed bulk-heterojunction solar cells. Their thermal, electrochemical, optical, charge-transport, and photovoltaic characteristics were investigated. These compounds exhibit strong absorption at 460-560 nm and low
