What could be the possible reasons responsible for poor fill factor in Si thin film solar cells?

I am working on Si thin film solar cells. I got voc of near 500 mV and Isc of about 25 mA/cm2 but with the fill factor of about 19 % only. Aluminum was base electrode and TCO was the front...

Is annealing necessary in case of silicon thin film solar cells before I/V characteriation?

I have sprayed silicon solar cells (p-i-n) on a glass substrate. The sprayed films are not stable and can be removed easily by touching it. I think I need to go for annealing of the films but I...
