Mesoporous carbon (MC), carbon nanotube (CNT) and MC-CNT binary counter electrodes prepared with different MC/CNT weight ratios (m_MC/m_CNT) were first studied on the power conversion efficiencies (PCE). Further, CuS nanomaterials pre-prepared through hydrothermal method were added into, and then MC-CNT-CuS ternary counter electrodes were synthesized. The influence of CuS content as well as film thickness on the efficiency was also probed. The experimental results showed that when m_MC/m_CNT=3/2, the synergistic effect of the two carbon materials reached the maximum, resulting in the highest PCE of 12.69% for the binary MC-CNT counter electrode. The PCE after incorporation of 0.4 g CuS was improved to the highest value of 13.18% when the counter electrode was screen printed five times.
