The J-V characteristics and photovoltaic response of indium tin oxide/pentacene (d nm)/C{sub 60} (40 nm)/BCP (10 nm)/Ag (100 nm) devices have been systematically analyzed. By fitting the J-V characteristics of the fabricated devices, photocurrent densities J{sub ph} were obtained. Meanwhile, we proposed a modified optical transfer matrix theory to satisfy the reasonable trend between P{sub 0}R{sub 0} and film thickness of pentacene layers. Then, we revealed that an accurate rate of energy loss can be defined as E{sub loss}=1-betaJ{sub e}/P{sub 0}R{sub 0}. Also, the relationship between open-circuit voltage V{sub OC}, compensation voltage V{sub 0} and initial polaron-pair bounding energy E{sub B} was determined based on the detailed study and simulation of device photocurrent.
