EFFECTS OF PHOTOANODE THICKNESS ON THE PERFORMANCE OF DSSC SIMULATED USING EQUIVALENT CIRCUIT
In DSSC or any other solar cells, thick absorption layer is preferable as it can maximize the photo-generation of carriers. Unfortunately, the photo-generated carriers need to traverse through the thick layer before it can be collected at the photo-electrodes. This may lead to unwanted phenomena suc...
