To provide an integrated thin-film solar cell that prevents deterioration of hotspot resistance and has a high output voltage. A thin-film solar cell module comprising: a thin-film solar cell string comprising a plurality of thin-film solar cell elements interconnected in series, each of the thin-film solar cell elements including a surface electrode, a photoelectric conversion layer, and a back surface electrode laminated in this order, the thin-film solar cell module being configured so that the number of stages n of the series connection of the thin-film solar cell elements in the thin-film solar cell string satisfies the following formula (1): n<Rshm/2.5/Vpm×Ipm+1  (1), wherein Rshm is the most frequent short-circuit resistance value of the thin-film solar cell elements; Vpm is an optimum operation voltage of the thin-film solar cell elements; and Ipm is an optimum operation current of the thin-film solar cell elements.
