PClTO2, eco-friendly green material with high device performance efficiencies
Low cost, high purity polymer available online for priority dispatch
PClTO2 is an alternating copolymer with benzodithiophene (BDT) and thiophene carboxylate ester as the main backbone units. It has great solubility in the common solvents due to its simple structure.
PClTO2 can be used for highly efficient lower cost non-fullerene polymer solar cells (NF-PSCs) with the advantage of being able to be processed in eco-friendly non-halogenated solvents i.e. THF, o-xylene and 1,2,4-trimethylbenzene.
PClTO2 is first developed at Ossila as one of the green energy materials. Both PClTO2 and PTO2 are eco-friendly green energy materials and good replacements for PM6 and PTB7-Th with simpler structures at lower costs while maintaining high device performance efficiencies. No literature concerning PClTO2 or the same chemical structure was detected at the time of the product launch at Ossila.

Cyclic Voltammetry
The cyclic voltammograms (CV) measurements were recorded on Ossila Potentiostat by using a three-electrode system with platinum disc as the working electrode, platinum wire as the counter electrode, Ag/Ag+ electrode as the reference electrode with a scanning rate of 100 mV/s in a 0.1 M tetrabutylammonium perchloroate Bu4NClO4) solution. The potential of Ag/Ag+ reference electrode was internally calibrated by using ferrocene/ferroncenium (Fc/Fc+) as the redox couple.
