A new optimum design, in which the actual daily spectral data under outdoor conditions over a year were considered, was developed for the integrated tandem‐type a‐Si solar cell submodule with a structure of glass/TCO/a‐Si: H(pinpin)/metal. It was found by this design that the optimum cell number connected in series, at which maximum total annual output power was obtained, was small compared with that obtained by the conventional optimum design under standard conditions (AM1.5, 100 mW cm −2 ). It was also found that when light‐induced degradation was considered, the thickness of the i‐layer for the second pin cell was thinner than that by the conventional optimum design.
