Question

With justification, how would you expect the efficiency of your DSSC to change with time?

Answer 1

DSSC the name implies, the mechanism of dye solar cells is based on the photo electrochemical processes and theefficiency η is the ratio between maximum generated power Pmax and electrical input power Pin from the light source .

Or

The power conversion efficiency (n) was calculated using the following described relation:

n= FF×Isc×Voc/P

Where Isc is the short-circuit photocurrent density (A cm−2)

Voc is the open circuit voltage (V),

FF is the fill factor

P is the intensity of the incident light (W cm−2) which is changes with time so efficiency will changes with time
