Solar Panel Efficiency and Temperature

Click For Summary
SUMMARY

The efficiency of solar panels decreases with increasing temperatures, primarily due to the rise in reverse leakage current. This effect is not linear, as higher temperatures lead to a significant drop in performance. Research indicates that at sub-freezing temperatures, the reverse leakage current remains stable, suggesting that lower temperatures do not negatively impact efficiency as one might expect. The introduction of transparent, flexible solar cells represents a significant advancement in solar technology.

What affect does the temperature of a solar panel have on it's efficiency? I know they become less efficient at higher temperatures, but is this effect linear? Would decreasing the temperature sub-freezing temperatures do anything?

On a related note, apparently they have invented a transparent, flexible solar cell. http://news.yahoo.com/blogs/this-co...ansparent-flexible-solar-cells-131334623.html

I think the main issue with higher temperatures is that the reverse leakage current increases with temperature. This abstract seems to indicate that at lower temperatures, the reverse leakage current is independent of temperature (which seems strange to me):

If you have access to IEEE papers, you can read the whole text (I do not).
