Abstract
Applications of poly3hexylthiophene P3HT to solar cells have been reported The reliability of organic solar cells is a key factor of fullscale applications in commercial optoelectronics In this study the environmental effect on the carrier transport in P3HT is researched Chargetrapping phenomena are studied through timedomain measurement for P3HT thinfilm transistors The timedomain data confirm the holetrapping model indicating that water vapor influences the response by producing additional hole traps that serve to increase the current time constant To understand the P3HT degradation mechanisms an analysis through the temperaturedependent transfer characteristics is presented It is shown that the hopping conduction behavior can be affected by exposure to ambient humidity and ambient atmosphere inducing fluctuations in the hopping distance and the barrier height for hopping that serve to influence the carrier mobility
