WUHAN, China (May 22, 2015) - Wuhan Optoelectronics Forum No. 97 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the afternoon of May 22.
I-V curve is the most important method to describe solar cells. Physical processes at the interfaces play a key role in small organic molecules devices. Therefore we focus on the influence of interfacial processes on the I-V curve.It has been confirmed that the degradation of ITO/organic interface is the main reason for the appearance of S-shape I-V curve. An improved equivalent circuit model has been proposed. Insertion of MoOx layer can avoid the appearance of the S-shape I-V curve and thereby greatly extend the lifetime of the device. The dependence of the photocurrent originating from the excitons in the CuPc or C60 layer is quite different. It has been suggested that the triplet exciton-electron interaction in C60 layer is the main reason of this phenomenon.
