    • 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.
    • 一种在制造过程中通过在太阳能电池元件的基板侧和背面电极之间施加伪交流电压来消除薄膜太阳能电池元件短路的方法。 伪交流电压的波形可以是正弦波,半波正弦波,锯齿波,方波等。 相反方向的峰值电压达到太阳能电池元件的反向击穿电压,波形可能包含较小的正向分量或无分量。Se反向的峰值电压也可能会瞬间超过反向击穿电压。 伪交流电压的周期与由太阳能电池元件的容量和反向电阻确定的太阳能电池元件的齿数恒定相匹配。 伪交流电压引起对太阳能电池元件中的累积电荷进行放电的交流电流,从而保护其免受由累积电荷产生的高压。 因此,该方法有效地消除半导体层中的短路而不损坏半导体层的非短路部分。
