摘要:
This invention provides a method of fabricating a thin-film photovoltaic module having a structure in which a plurality of thin films are stacked. This method includes postulating a substrate temperature during laser scribing for each thin film, determining a scanning pattern by taking account of the size of the substrate at the postulated temperature, and dividing each thin film in accordance with the scanning pattern while keeping the substrate temperature at the postulated temperature or a temperature in its neighborhood.

A method for removing short circuits in thin film solar cell elements during manufacturing by applying a pseudo-alternating voltage between the substrate side and the back electrodes of the solar cell elements. The waveform of the pseudo-alternating voltage may be a sinusoidal wave, a half-wave sinusoidal wave, a sawtooth wave, a square wave or the like. The peak voltage in the reverse direction is up to the reverse breakdown voltage of the solar cell element, and the waveform may either contain a small forward component or no fond component The peak voltage in Se reverse direction may also momentarily exceed the reverse breakdown voltage. The period of the pseudo-alternating voltage matches the tine constant of the solar cell element determined by the capacity and reverse resistance of the solar cell element. The pseudo-alternating voltage induces an alternating current which discharges the accumulated charges in the solar cell element, thereby protecting it from high voltages generated by accumulated charges. Consequently, the method effectively removes short-circuits in the semiconductor layer without damaging non-short-circuited sections of the semiconductor layer.

摘要:
A device for determining a deterioration of the catalytic converter for an engine equipped with a catalytic converter disposed in the exhaust passage and upstream and downstream air-fuel ratio sensors disposed in the exhaust passage upstream and downstream of the catalytic converter, respectively. The device also determines whether the three-way catalyst in the catalytic converter has deteriorated based on the output signal of the downstream air-fuel ratio sensor when the air-fuel ratio of the engine is feedback controlled by the output of the upstream air-fuel ratio sensor, wherein the execution of the determining operation of catalyst deterioration is prohibited when the period of the cycle of the air-fuel ratio feedback control becomes longer than a predetermined value, thereby preventing errors from accuracy in the determination.
