Numerical simulation of highly efficient dye sensitized solar cell by replacing the liquid electrolyte with a semiconductor solid layer

To resolve the difficulties regarding the use of liquid electrolyte, a solid-state dye-sensitized solar cell (SS-DSSC) was simulated in which a P3HT layer acts as a hole collector instead of liquid electrolyte. SS-DSSC indicated a favorable performance deliver a short-circuit photocurrent of 12.70 mA cm−2 and open-circuit voltage of 0.67 V.
