© 2018 The Authors. Poly(N-vinylcarbazole) (PVK) has been used as additive in the I - /I 3- redox electrolyte and the photoelectrochemical effect of PVK with various concentration to the photovoltaic performance was studied. Under optimum condition, a maximum efficiency of 6.3% was achieved with a current density of 19.31 mA/cm 2 at the addition of 30 μL THF solution to the electrolyte which is 45 % improved photovoltaic performance compared to that of bare electrolyte. This could be attributed that the electron rich PVK increases the basicity of the electrolyte medium and increases the catalytic reduction of I 3- ions. So, the increased dye regeneration rate improved photovoltaic performance.
