Synthesis and photovoltaic properties of a low bandgap BODIPY–Pt conjugated polymer†
Abstract
A conjugated boron-dipyrromethene (BODIPY)–platinum polymer possessing a low bandgap of 1.7 eV has been synthesized and characterized. Bulk heterojunction solar cells employing this polymer gave high open circuit voltages up to 0.92 V and power conversion efficiencies close to 1%.
