Abstract

Polymer:fullerene bulk-heterojunction hybrid solar cells with the structure indium tin oxide (ITO)/poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate)(PEDOT:PSS)/poly(3-hexylthiophene)(P3HT):[6,6]-phe nylC61-butyric(PCBM)/bathophenanthroline(Bphen)/Ag were fabricated. In this paper, the electrical characteristics of bulk heterojunction organic solar cells with various thickness of P3HT:PCBM as the active layer and Bphen as an exciton-blocking layer(EBL) were studied. The results showed that the P3HT:PCBM layer at about 110nm perform best, the open circuit voltage(V_oc) , short circuit current(J_sc) and the power conversion efficiency(PCE) reach to 0.57V, 10.82mA/cm², 2.50%, respectively; then when Bphen was 1nm, Voc is 0.56V, J_sc is 12.64mA/cm², PCE reach the maximum 3.30%.
