摘　　要：Hybrid organic-inorganic solar cell devices were fabricated utilizing macroporous n-type GaP and poly（3,4-ethylenedioxythiophene）：poly（4-styrene sulfonate） （PEDOT：PSS）. The high-aspect ratio structures of the macroporous GaP resulted in higher photocurrent and external quantum yield as a function of wavelength. Photocurrent-voltage measurements as a function of light intensity revealed information on the dependence of short-circuit current （Jsc） and open-circuit voltage （Voc） on light intensity. Under 1.0 Sun illumination, hybrid macroporous GaPJPEDOT：PSS devices showed Jsc of 2.34 mA cm 2, Voc of 0.95 V, fill factor of 0.54, and overall efficiency of 1.21%. The extent of the influence of dopant density of GaP on hybrid device performance was probed with current density-voltage measurements. The addition of a gold nanoparticle coating on macroporous GaP prior to PEDOT：PSS coating showed increased device performance, with overall efficiency of 1.81%. Gold-modified planar GaPJPEDOT：PSS showed decreased Jsc and Voc values and lower external quantum yield over all wavelengths,Hybrid organic-inorganic solar cell devices were fabricated utilizing macroporous n-type GaP and poly（3,4-ethylenedioxythiophene）：poly（4-styrene sulfonate） （PEDOT：PSS）.
