Abstract


We present the QE results of a new air stable organic semiconductor UV photocathode P3HT. QE was measured as a function of wavelength in spectral range 190-250nm. It shows nonnegligible QE near 230nm. Though QE is low as compared to CsI but due to ease of preparation of large area photocathodes and air stability it may replace CsI in some experiments where photon flux is high.
