Module construction of dye-sensitized solar cells by using chemical etching

Module construction of dye-sensitized solar cells (dsscs) by using chemical etching was found as a simple process to characterize and optimize the size of unit cell in terms of photovoltaic performance of the resulting module. This method was also a simple and promising process to enlarge dssc size and commercialize dssc module. Under high intensity irradiation, the deleterious effect of internal resistance in the unit cell of dssc module was found to become significant on the photovoltaic performance of the system. Meanwhile, high active area dssc module that is always accompanied by the low external resistance gives rise to the high photovoltaic performance of the system under low intensity illumination. Accordingly, optimization of the size of unit cell is worthwhile to note for the optimum performance of resulting dssc module under a particular illumination source.
