When a plurality of solar battery modules are to be connected, terminals formed on the rear surfaces of these solar battery modules are connected by electric wires. This wiring is very cumbersome work, so power output wires from a plurality of solar battery modules get tangled together to cause connection errors. In a solar battery module including a cover member for supporting a photovoltaic element, and a structure support member having a portion which forms an angle or a curved surface with respect to the cover member, an electric connecting terminal is formed at an opening of the structure support member, and a locking member at least partially formed by a continuous body is inserted into the structure support member. In this way, the solar battery module is fixed and/or electrically connected.

A semiconductor ceramic contains erbium as a semiconducting agent in primary components of barium titanate, strontium titanate, lead titanate and calcium titanate, with the average grain diameter of the semiconductor ceramic exceeding about 5 &mgr;m but not exceeding about 14 &mgr;m. Further, the semiconductor ceramic contains as additives a compound containing Er with the Er being more than about 0.10 mol but no more than about 0.33 mol, a compound containing Mn with the Mn being about 0.01 mol or more but no more than about 0.03 mol, and a compound containing Si with the Si being about 1.0 mol or more but no more than about 5.0 mol, per 100 mol of the primary component. Thus, a semiconductor ceramic and positive-temperature-coefficient thermistor can be provided with high-flash-breakdown capability, excellent results in ON-OFF application tests and few irregularities in resistance values.

Provided are a plug that makes it possible to readily connect a power supply such as a solar battery or fuel cell to an external load or system power and to enhance safety, as well as a power converter and power generating apparatus having the plug. The plug has a movable insulating member for covering the plug electrodes when the plug is connected to an outlet and for exposing the electrodes when the plug is not connected to the outlet. In another example of the plug, the plug has at least two electrodes and switches corresponding to respective ones of the electrodes, wherein the switches are opened (turned off) when the plug is pulled out of the outlet. In still another example of the plug, the plug has at least two electrodes and a switch that is opened/closed in dependence upon the state of the connection between the electrodes and the outlet. When the plug is connected to the outlet, the switch is closed (turned on) to thereby sense the fact that the plug has been connected to the outlet.

A solar cell module has an outermost surface comprising a surface member on the light receiving face side of the solar cell module, a back face comprising a back face member on the non-light receiving face side of the solar cell module, and a photovoltaic element between the surface member and the back face member. The solar cell module is characterized in that it has a porous incombustible member having a structural strength between the photovoltaic element and the back face member. A solar cell-bearing roof and a solar cell power generation system in which the solar cell module is used are also disclosed.
