Abstract	Understanding charge transfer in organic semiconductors is important for developing devices like organic light emitting diodes and flexible electronics. Optical tweezers have been used in many disciplines for trapping, manipulating, and analyzing microscopic objects such as microspheres, micro-organisms, and other colloidal particles. Using optical tweezers, studies have measured the average charge on silica microspheres coated with an organic semiconductor. We take this technique further by developing a new method for measuring charge using the amplitude of oscillation for an electrically driven microsphere to measure the surface charge with a time resolution of up to 300 Hz. This method can be used for measuring the charge transfer of donor-acceptor organic semiconductors such as ADT-TES-F and PCBM.
