Solar Panel Efficiency and Temperature

AI Thread Summary
Higher temperatures negatively impact solar panel efficiency, primarily due to increased reverse leakage current, although the relationship is not strictly linear. Decreasing temperatures below freezing may not significantly enhance efficiency, as the reverse leakage current appears to be temperature-independent at lower levels. The discussion also highlights the development of transparent, flexible solar cells, which could represent a significant advancement in solar technology. The complexities of temperature effects on solar panel performance warrant further investigation, particularly through academic research. Understanding these dynamics is crucial for optimizing solar energy systems.

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).
 
Thanks Berkeman!
 
I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
