Hypothetically the only thing that it should change is the total device area, which in practice has some effect on PCE's obtained due to film uniformity, depending on your manufacturing technique. However from what I've seen, performance of perovskite cells can change with the time of day/weather, so whatever you do try to be consistent with it.

Dear Mr. Abdi

You can read the following paper to answer your question

Effect of electrode geometry on photovoltaic performance of polymer solar cells

Dear Mojtaba,

I guess there is no differences. We had the experience of using two different patterns for Au contacts for perovskite solar cells and found no differences. However, we used a plastic mask on the device to know the exact amount of device area. On the other hand, when you use a pattern with higher area of contact, it helps to contact to wire in I-V measurement  with more ease

Of course. The shape of electrode can influence the performance of perovskite solar cells (PSCs). In order to accurately measure the efficiency  of PSCs, a mask/aperture is used for measurements. See the attached file ''Reporting Checklist For Solar Cell Manuscripts'' from Nature Publishing Group.
