PTEG-1 has a considerably higher dielectric constant than PCBM. It was recently published that the efficiency of polymer-fullerene organic solar cells can be increased by using compounds that have high dielectric constants. Also, the use of PTEG-1 as an electron-conducting layer increases the efficiency of perovskite solar cells.
