A systematic analysis between the efficiency of an ideal PV cell and its energy gap under different lighting condition is provided in Freunek Müller, Freunek, and Reindl (2013), but no model is given for the IPV dynamic behavior. Moreover, the necessity of a detailed model or simulation environment for the cell design (after choosing the material) is addressed. Also, some researches such as Gorlatova, Wallwater, and Zussman (2013) provide a trace of indoor lighting and its energy model as a combination of sunlight and artificial lighting.
