Nanohybrids consisting of Au nanocluster and polythiophene nanowire assemblies exhibit unique thermal‐responsive optical behaviors and charge‐transfer controlled magnetic and optoelectronic properties. The ultrasmall Au nanocluster enhanced photoabsorption and conductivity effectively improves the photocurrent of nanohybrid based photovoltaics, leading to an increase of power conversion efficiency by 14 % under AM 1.5 illumination. In addition, nanohybrids exhibit electric field controlled spin resonance and magnetic field sensing behaviors, which open up the potential of charge‐transfer complex system where the magnetism and optoelectronics interact.
