Panchromatic OsII sensitizers for dye-sensitized solar cells (DSCs) were prepared. A DSC based on TF-52 (see picture) showed promising performance characteristics: short-circuit photocurrent density JSC=23.3 mA cm−2, open-circuit photovoltage VOC=600 mV, fill factor (FF)=0.633, and power conversion efficiency η=8.85 % under AM 1.5G simulated one-sun irradiation.
