초록

We have fabricated solar cell devices based on zinc-phthalocyanine(ZnPc) as donor(D) and fullerene(C60) as electron acceptor(A) with doped charge transport layers, and BCP and $Alq_3$ as an exciton blocking layer(EBL). We have measured the photovoltaic characteristics of the solar cell devices using the Xe lamp as a light source. We were use of $Alq_3$ layer leads to external power conversion efficiency was 2.65% at illumination intensity $100mW/cm^2$. Also we confirmed the optimum thickness ratio of the DA hetero-junction is about 1:2.
