  We present a solution of Einstein equations describing a $d$-dimensional
planar quintessence AdS black hole which depends on the state parameter $w_q$
of quintessence. We investigate holographic superconductors in this background
and probe effects of the state parameter $w_q$ on the critical temperature
$T_c$, the condensation formation and conductivity. The larger absolute value
of $w_q$ leads to the lower critical temperature $T_c$ and the higher ratio
between the gap frequency in conductivity to the critical temperature for the
condensates. Moreover, we also find that the scalar condensate there exists an
additional constraint condition originating from the quintessence
$(d-1)w_q+\lambda_{\pm}>0$ for the operators $\mathcal{O}_{\pm}$, respectively.
Our results show that the scalar condensation is harder to form and the
occurrence of holographic dual superconductor needs the stronger coupling in
the quintessence AdS black hole spacetime.
