A reverse biasing apparatus is used to remove short-circuited portions in a solar battery module having multiple strings of solar cells each including a first electrode layer, a photovoltaic semiconductor layer and a second electrode layer formed on a glass substrate, by applying a reverse bias voltage between the electrodes of adjacent solar cells. The reverse biasing apparatus comprises probes to be in contact with the electrodes of adjacent three or more strings of solar cells, an actuator for actuating the probes up and down, and a relay switch for selecting, from the probes, a pair of probes for applying the reverse bias voltage between the electrodes of an arbitrary pair of adjacent solar cells. The use of the reverse biasing apparatus can ensure an efficient reverse biasing process on a solar battery module having integrated multiple strings of solar cells.

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