Graphene assistance enhanced dye-sensitized solar cell performance of tin sulfide microspheres

- The nanosheet-assembled SnS2 microspheres were synthesized.
- The photovoltaic properties of nanosheet-assembled SnS2 microspheres physically mixed with graphene were first investigated.
- The excellent conductivity of the graphene and the superior electrocatalytic activity of the tin sulfide provide good performances of the device.
- The results showed that the conversion efficiency reached to 7.46% with the addition of 6 wt% reduced graphene.
