Bifacial semi-transparent perovskite solar cells (PSCs) are highly attractive for improving the efficiency of tandem solar cells and extending bifacial photovoltaic applications.

You could use that silver paste for check your device whether working or not. Moreover, it is depends on your HTM. Because, Silver paste penetrate through spiro-MeOTAD and affect the perovskite. So, you need to deposit MoO3 on the top of PSK. So, pls choose your HTM before using silver. I am not sure that silver paste can give better device performance.

Thank you sir for your valuable suggestion and time.

Dear Neetika Yadav ,

Silver paste is used to make a metal spot to access the solar cells electrically since one can attach to bit a wire which can be used for the electrical connection of the device. It is instead of the pressure electrode.

If you can use it directly as a cathode of your perovskite solar cells without an electron transport layer you can make an experiment. It will not take much time.

But may be the problem as said before that solver of the silver paste may re dissolve the perovskite layer is it soluble in that solvent.

But may be the proposal of Pavithrakumar Palanichamy helpful.

Best wishes

Respected Abdelhalim abdelnaby Zekry sir,

I will keep it in my mind while performing an experiment.

I sincerely thank you for your valuable suggestion, time and attention.
