β-HgS superspheres with uniform sizes and micro-sub-planes were synthesized by hydrothermal method. The β-HgS superspheres have very strong absorption in a wide wavelength range from ultraviolet to visible region. In addition, they show good photovoltaic behavior with short circuit current density of ～0.12 mA·cm-2, open circuit voltage of ～0.4 V, fill factor of ～4.4%, and energy conversion efficiency of ～0.21%.
