Solar cell simulations without using Simpowersystems or Simelectronics toolbox

Dear A Jenkins Now that you have answered my question when it is unusual. Thanks for the comment. I do not wanted to cheat. I can see now only people open their eyes. Before that no one wanted to reply. When silly questions are there everybody wanted to comment. That is funny and strange. I have developed a good solar model but how do you get a plot of output current and voltage with only one input Sun-Light That is how it should normally work in nature rather that giving two inputs to the model.(Current) Kind Regards
