Thieno[3,4-c]pyrrole-4,6-dione (TPD) based conjugated polymers as an electron donor, acceptor and single-component for application in organic solar cells in the past ten years have been intensively reviewed in this Feature Article.
The right amount of vinyl units is the key to obtaining crosslinkable PBDTTPD resulting in a PCE of 6.06% and maintaining 91% performance after 150 °C treatment for 40 h.
In this review, we summarize the recent development of the multifused ladder-type conjugated building blocks for making donor–acceptor conjugated copolymers.
Three conjugated polymers based on the thieno[3,2-b]indole (TI) unit as electron-donor block and benzothiadiazole (BT) as electron-accepting block and thiophene rings as spacers. Their photovoltaic performance were finely tuned by thiophene spacers.
