| 摘要 |
The present invention provides a thin film photoelectric conversion module (1), including a substrate (2) and a plurality of thin film photoelectric conversion cells (10) formed on the substrate (2) and connected to each other in series to form a series-connected array (11). Where the light to one of the cells (10) is intercepted, the particular cell (10) is prevented from being heated to an excessively high temperature by suppressing the behavior of the cell (10) as a diode through repeatedly applying a reversed bias voltage to each cell (10), by preventing a large current from flowing through the light-intercepted cell (10) through employing the construction that a plurality of series-connected arrays (11) each having a sufficiently low short-circuit current are connected to each other in parallel or through using a plurality of sub-arrays each having a sufficiently low short-circuit current for forming the series-connected array (11) and connecting bypass diodes to these sub-arrays, respectively, in parallel, or by facilitating occurrence of short-circuiting in the light-intercepted cell (10) through arranging a metal portion that is partly in contact with the thin film photoelectric conversion unit. |
