Hema Karunadasa | Instability and toxicity of lead-halide perovskite solar-cell absorbers

[@AbdolazimHasseli]

As a beginner to Perovskites, I learned a lot from this lecture. Thank you.

[@kishwarkhan224]

Very impressive talk indeed, I fall in love with perovskites

Was extremely helpful, Thank you very much DR. Hema Karunadasa.

In other words, the 2D is better than the 3D structure. Nice one thank you very much, I have just picked a great interest on this perovskite Sc from Prof. Mike McGehee. Thank you.

this was quite Impressive, informative talk. I watched this thrice, you address here the most important issues instability/degradation, doping, photo luminescence , single junction and tandem solar cells. this lectures of yours clear many doubts. Dear Maam, During the Talk you mentioned the toxicity of Pb and Cd, and Pb being water soluble contaminates the water ways. But CdI2 is insoluble so can be contained. I want to make this point clear here that If CdI2 is relatively better than PbI2 from toxicity perspective, and if I get the enhanced absorption range on CdI2 doping.

khurshid parray Really informative talk indeed. I didn't seem to get the last part of your statement. What point are you trying to make clear?

Hii Mam, hope u are well... I want some notes or lectures about how u calculate efficiency from the current-voltage graph...r u help me, with how can I calculate efficiency from the current-voltage graph...plz kindly help me

Thanks!!! Really helpful!!! Keep it up!!!

I did it with Avasva plans.

Did you try polymerisation of this material in the constant of water proofing the lead-halide perovskite? Tin Oxide is the replacement for lead oxides in low fired ceramic glazes. Tin Dioxide is another path en.wikipedia.org/wiki/Tin_dioxide pubchem.ncbi.nlm.nih.gov/compound/Stannic_oxide#section=Top tin.atomistry.com/stannous_iodide.html pubs.acs.org/doi/abs/10.1021/jacs.5b13470 en.wikipedia.org/wiki/Tin_based_perovskite_solar_cells
