What has caused this apparent stagnancy, in the development of more efficient solar cells?

I suspect it's a combination of three factors: First, there's a fundamental limit of the efficiency of solar cells. A solar cell is effectively a heat engine that uses the 6000K Sun as the heat ...

Geometrical Optimization not converging for a double perovskite quantum dot, using Gaussian

OK, I do not want to be that guy, but I will be that guy. Some general remarks You should plan better your calculation projects. You got 129 SCF cycle calculated in about 3 days. Even if this ...

Geometrical Optimization not converging for a double perovskite quantum dot, using Gaussian

I didn't deal with perovskite before, but I got this problem when I used metal atom in my complex. So, from my point of view, I think your calculation needs more cycles to get converged so what about ...

Geometrical Optimization not converging, where am I going wrong?

Where was I going wrong- the quantum dot structure was not neutral. Thanks to @AnoopANair, I was able to find the problem. For anyone having a similar problem look at this video - https://www.youtube....
