Fig. 4From: Significant Detectivity Enhancement of Broad Spectral Organic–Inorganic Hybrid Photodiodes by C60 Film as Hole-Blocking Layera The dependence of photoresponsivity R on the wavelength. b The logarithmic dependences of R on the incident optical power Pin. All results were obtained at a reverse bias voltage of − 10 V and an incident optical power of ~ 0.1 mWBack to article page
