  8. 8. Commonly used DONORS ( p-type Materials): • MDMO-PPV : Poly[2-methoxy-5-(3′,7′- dimethyloctyloxy)-1,4-phenylenevinylene] • F8T2 : Poly(9,9-dioctylfluorene-co- bithiophene • PFDTBT : Poly{[2,7-(9,9-bis-(2-ethylhexyl)- fluorene)]-alt-[5,5-(4,7-di-2′-thienyl-2,1,3- benzothiadiazole)]} • Commonly used Acceptors (n-type Materials): • PCBM-60 : Phenyl-C61-butyric acid methyl ester (3% efficiency) March 17, 2015 8
  9. 9. •BHJs are used as active layers •Optical photons absorbed and creates exitons (bound electron-hole pair). •The negative electrode is Aluminum. •Indium Tin Oxide(ITO) is the common transparent electrode. •The substrate is glass. •Current is generated when the resulting free electrons and holes are transported through the donor polymer and acceptor fullerene, respectively, to the electrodes.
