This is to study the effect of temperature on Solar Cell Performance.
we have studied the cell characteristics of ZnS based PV solar cell in light and in dark taking AM as 1.5. Does it seem helpful to you?
The output of Si cells vs. temperature is well documented. However I have not seen much work on the 2D temperature distribution on an array of solar panels or the 2D temperature distribution in a panel with an array of individual cells.
I have observed the changes in the 2D temperature distribution in an array 13.7M x 3.8M in the period from 0.5 hours before sunrise to 1.5 hours after sunrise. The changes in temperature were gauged by observing the "melt profile" of the array covered evenly by a "uniform" layer of frost.
The melt profile on average reflected the increasing solar radiation as the altitude of the sun increased. But individual panels showed individual temperature profiles that took some explaining. Eg. The areas where the junction boxes were fixed to the panel were " hotter" than the rest of the individual panel. Other panels indicated that the increase in panel temperature was not constant over the whole panel.
The ramification of these observations are that in summer the panels themselves may have slightly different temperatures.
To analyse these temperature effects will require modelling the panels themselves and predicting the temperature profile by solutions of the 2D differential equations with a suitable boundary conditions. This is quite a complex piece of analysis where on one side is a complex plate enclosed in an air filled volume where one models the cell temperature based on incoming radiation and radiation from the cells and energy loss from the cells due to convection.
This would be a "nice" academic exercise taking many disciplines to arrive at a Good answer. I guess it may be of use in optimising utility sized installations.
I have performed the analysis in quantifying the effects of cell temperature on PV cell but apparently from what I have come across, finding out the exact PV cell temperature itself is a quite a task. The transient analysis of solar cells (not "light pulse" based analysis) requires great deal of modeling.
I have been working on refining the model and will soon publish it as I reach the final values.
I assume, Vijaykumar Ramalingam is interested in the spatial temperature distribution on PV modules. We have measured module temperature in Egypt and in Stuttgart (Hohenheim) during the course of the day at varying irradiation. We cooled down part the mudels by a water film applyed on the surface (combined cleaning and cooling, cleaning is essential in arid climates like Egypt). Increase of PV efficiency by cooling was higher than decrease by sun light reflection and absorbtion due to the water film. We measured the module temperature by themocouples. Now, by this dicussion I get the idea to measure spatial temperature pattern by thermography using our IR-cameras, as we do to measure plant canopy temperature.

We measured the ambient temperature, irradiation and wind speed using a weather station and then we estimated the cell temperature and irradiation on the surface of the panels considering tilt angle of the panels, position of the sun and the day of the year. Is this useful for you?
Thermal analysis of different types of PV cells is done in this research paper
We calculated the temperature profile of solar modules. You can look at the study by following the paper in the link:Article M.S. Farid, A Zekry, A.A. El-Shazly, and M.A. El-Koosy, “Eva...
