Wide Bandgap Polymer

A novel wide bandgap polymer PTZP with Eoptg of 2.01 eV was designed and synthesized. PSCs based on PTZP exhibited high PCE of 11.8%. PCEs of over 10% were obtained with an active layer thickness of 200 nm or an area of 0.81 cm2. PTZP was shown to be a promising conjugated polymer for the fabrication of efficient large area PSCs.
