Poly (3-hexylthiophene)(P3HT) is the widely used in configuration of polymer solar cells. In order to correlate improvement in mobility with an improvement in power conversion efficiency of solar cell, organic field effect transistor (OFET) is investigated, which can easily extract mobility basing on I-V characteristic. Experiment shows that mobility of P3HT increase 290% after annealing. Also several experiments are done to diagnose larger deviation problem among chips to chips.
