%X We present a model connecting the cosmic star formation rate (CSFR) to the growth of supermassive black holes. Considering that the evolution of the massive black hole is dominated by accretion (Soltans argument) and that the accretion process can be described by a probabilistic function directly regulated by the CSFR, we obtain the evolution of the black hole mass density. Then, using the quasar luminosity function, we determine both the functional form of the radiative efficiency and the evolution of the quasar duty cycle as functions of the redshift. We analyse four different CSFRs showing that the quasar duty cycle, d(z), peaks at z similar to 8.511 and so within the window associated with the reionization of the Universe. In particular, dmax similar to 0.090.22 depending on the CSFR. The mean radiative efficiency, , peaks at z similar to 0.11.3 with depending on the specific CSFR used. Our results also show that it is not necessary for a supercritical Eddington accretion regime to produce the growth of the black hole seeds. The present scenario is consistent with the formation of black hole seeds similar to 103 M? at z similar to 20.
