Abstract :
An organic thin film photovoltaic cell (OPV) consists of many thin layers of quite different materials: glass substrate, transparent electrode such like indium tin oxide (ITO), organic molecules such like copper phthalocyanine (CuPc), fullerene (C60) and metal (Me), etc. Unit structure of the OPV generates voltage less than 0.5V, and thus it is required to construct a module in which the units form a tandem series. The tandem structure preferably be formed ´in plane´ rather than vertical stacking form.
