Enhancement of ternary blend organic solar cell efficiency using PTB7 as a sensitizer
We demonstrate a significant improvement of power conversion efficiency (PCE) by the
addition of the polymer Poly [[4.8-bis [(2-ethylhexyl) oxy] benzo [1, 2-b: 4, 5-b′] dithiophene-
2, 6-diyl][3-fluoro-2-[(2-ethylhexyl) carbonyl] thieno [3, 4-b] thio-phenediyl]](PTB7) to a Poly
