    摘要: A thin film solar cell is proposed, in which the surface of the semiconductor layer (20) facing the front contact (28) is designed as an inversion layer, which can be tunnelled through by the charge carriers electrons and holes.

    摘要: An optoelectronic apparatus is provided for identifying marks comprised of defined contrast patterns, particularly barcode symbols. The device includes a transmitting element which emits transmitted light and a receiving element. The transmitted light is guided across the marks, and the received light reflected by the marks has an amplitude modulation imposed by the contrast of the marks, with the received light being converted into a voltage signal that forms the received signal in the receiving element. The voltage signal is converted into a binary signal and filtered by an arrangement of digital filters for compensation component stipulated distortions prior to being fed to a threshold-value unit for evaluation of the contrast pattern.
