Hello Mad People! My name is Chas and I am a year 12 student at Eltham High School. For my physics class I am curently carying out a experiment to investigade the voltage out put of a silicon photovoltaic cell vs light colour and intensity. I was investigating the effect of changing the temp on the voltage out put and I found that as temperature increases the voltage output decreases. When this relationship is graphed a negative cubic is formed which has a point of inflection at 25 degrees. Can you explain this? It is my understanding that the power output remains constant regardless of temperature but I dont know why the voltage output changes. My hypothesis that it is a design feature which limits the variation in the output due to increased light intensity as this is usualy associated with a temperature increase. Apart from this I am at a loss to explain my results along with the many people I have asked. Can you help?
