摘要：

A general model of calculating the short circuit photocurrent and exciton diffusion length from Schottky diode is given here using optical interference method. This method of estimating the exciton diffusion length can be very useful for those materials that do not give photoluminescence. It also serves as an accurate and simple method to determine the exciton diffusion length, which is an important material property to design devices such as organic solar cells. Our model is verified with the spectral response of indium tin oxide (ITO)/copper phthalocyanine (CuPc)/Al and ITO/CuPc/Ag Schottky diodes.
