Abstract

In the present work fabrication and characterization of Cu2S/Si
heterojunction photodiodes made by spray pyrolysis method using aqueous
solution of CuCl2.2H2O onto n-type silicon substrates made. The external
quantum efficiency of heterojunction was ٣7% at wavelength of 850nm. The
experimental results show peak relative responsivity around 100mA/w , and
maximum value of detectivity D* (2*1011cm.Hz1/2.w-1).
