We studied power dissipation in illuminated and non-illuminated photovoltaic cells using photothermal and electrothermal measurements as a modulated calorimetric method. We are able to identify, analyze and determine quantitatively the major power loss mechanisms due to their dominance under different bias conditions. To this end we have developed a model which we have applied to data measured under various conditions.
