The several attempts described above are examples of efforts
made by a number of researchers. Accordingly, the disadvantages of
non-monocrystalline silicon solar battery, such as photoelectric
conversion efficiency, deterioration, etc., are gradually being
improved. However, problems still remain. That is, when a solar
battery is configured by forming a semiconductor layer on a conductive
substrate with a zinc oxide layer therebetween, neither contact
between the conductive substrate and the zinc oxide layer, nor contact
between the zinc oxide and the semiconductor layer may be madesufficiently strong.
Therefore, minute separation may be caused in places at suchcontacts due to the influence of temperature or vibration given during
the step of forming the semiconductor layer and subsequent steps.
This results in a reduction in the photoelectrical conversion
efficiency of the solar battery, which is regarded as a problem interms of its initial performance.
Since the electrical resistivity of the zinc oxide cannot bemade so small as to be entirely neglected, the series resistance ofthe solar battery may be increased. This also results in a reductionin the photoelectrical conversion efficiency of the solar battery,which is regarded as a problem in terms of its initial performance.
Furthermore, the above-described problems may appear in cases
not only where a semiconductor layer is formed on a conductive
substrate, but also where a solar battery is made by forming asemiconductor layer on a transparent insulating substrate with atransparent electrode therebetween. That is, since the contact
between the transparent electrode and the semiconductor layer may
not be made sufficiently strong, minute separation may be caused inplaces between the transparent electrode and the semiconductor layer
during the manufacturing process. This also results in a reduction

in the photoelectrical conversion efficiency of the solar battery,which is regarded as a problem in terms of its initial performance.

When an acoustic signal 100, such as a collision sound that
occurs at the time of a traffic accident, is supplied to an accident
sound detection circuit 20, unnecessary signal components of theacoustic signal 100 are removed by a waveform shaping circuit 21,
which generates an output signal 101. The output signal 101 isconverted from an analog signal to a digital signal 102 by ananalog-to-digital (A/D) converter 22. The output digital signal 102
is then supplied to a differential signal processing circuit 23, which,in turn, outputs a differential signal 103 of the digital output
signal 102.
The differential signal 103 represents the variation of thedigital output signal 102: the more rapidly the digital output signal
102 changes, the larger the level of the differential signal 103.
Thus, even if the digital output signal 102 is large, the level ofthe differential signal 103 stays small as long as the digital output
signal 102 shows a small level of changes. Therefore, when an
emergency such as a traffic accident happens, the level of the output
signal 102 changes drastically.
Then, a reference differential signal value generating
circuit 25 is provided to generate a reference differential signal
value, which is compared with the differential signal 103 by acomparison circuit 24. When the differential signal 103 is larger
than the reference differential signal, the traffic accident
detection circuit 20 judges that it has detected a traffic accident,
and a trigger signal 110 is output from the traffic accident detection
circuit 20.
