It is well known that with the increase in temperature, the short circuit current value for a solar cell increases. However, while exploring some theoretical/simulation studies, I have observed for some materials that Isc could show decreasing trend with temperature. Could this be related to the lack of information required to compute the results or there could be some possible reason for this to happen?
I had recently found a paper in this regard (Article Temperature dependence of the short-circuit current in MIS solar cells
), however, this explains the observed trend in terms of thickness of the dielectric oxide layer. In usual solar cells, such layers are not regularly incorporated, and this is why I want to know the experts' opinions in this regard. Kindly share your views.Thank you.
Dear Omkar Rambadey
Generally, The short-circuit current from a solar cell depends linearly on light intensity, such that a device operating under 10 suns would have 10 times the short-circuit current as the same device under one sun operation.

Hi Dr Omkar Rambadey . Temperature is directly proportional to resistance. Increasing temperature will increase the resistance and so the current will decrease .
yes the short circuit current would tend to increase with temperature but voltage Voc decreases regularly and shows linearly behavior on this temperature conditions.
Dear Aref Wazwaz sir, thanks for sharing your view in this regard, I agree that resistance could increase with temperature, but for metallic systems. However, while talking about semiconductors, their resistivity and hence resistance would tend to fall with temperature due to a rise in carrier density. How can we then explain it.
Hello Qamar Ul Islam sir, thanks for your comment, yeah... I understand your point about the dependency of Jsc on illumination. However, if we keep illumination fixed and vary the temperature of device, do you expect Jsc would fall...
Thanks for your comment, Dr Hadi Jabbar Alagealy :)
Yes, Sir. These are the usually observed trends; however, do you expect Jsc to decrease with temperature under any specific circumstances for a solar cell constituted with all semiconducting layers.
