Dear colleagues, does any of you have access to information - what kind of carbon footprint have panels based on perovskite photovoltaic cells? Is it the same as with "ordinary" monocrystalline or polycrystalline panels? How is the built-in energy for the cells?
I've found only these:
monocrystal PV modules - c.a. 4750MJ/m2 and 242kgCO2/m2
policrystal PV modules - c.a. 4070MJ/m2 and 208kgCO2/m2

Dear Bartek,
welcome,
The perovskite solar cells has to go long way before commercialization for using in the field. This is because the instability of the solar cells in the long run. In addition to the toxic lead inclusion in the solar cells: https://tigerprints.clemson.edu/cgi/viewcontent.cgi?referer=&httpsredir=1&article=1001&context=elec_comp_pubs
Any how this is not the major issue of the question raised here. As the perovskite solar cell is fabricated at low temperature hence it will consume much lower energy for fabrication even less than the polycrystalline silicon. I would assume to save the same increment of energy as the difference from single to polycrystal.
As per your data in the question this energy increment is 700 MJ/m^2.
So i would assume that the pervoskite panels will consume about 3300 MJ/m^2
with emission of 172 kg CO2/m^2
Best wishes
Abdelhalim Zekry, thank you very much for the information; I realize that this is the beginning of the "journey" with pervoskites. Nevertheless, it is important to me to know (more less) in what area they place themselves in the context of the co2 footprint and embodied energy.
