摘要:
A solar cell coating and a method for manufacturing the solar cell coating. The solar cell coating is formed by adding a low bandgap material, a semiconductor material and a conductive polymer to a solvent or performing high-temperature milling on a mixture formed by mixing a conductive polymer material, a low bandgap material and a semiconductor material so that the solar cell coating exhibits high capability in transporting carriers effectively to transmit the electrons and holes to respective electrodes rapidly. Since the low bandgap material exhibits a small bandgap, MEG takes place to generate a plurality of electro-hole pairs when a photon is absorbed by the low bandgap material. Besides, by mixing the three materials corresponding to different conductive and valence bands respectively, a ladder structure formed by the HOMO and the LUMO corresponding to the three materials respectively will assist effective and rapid carrier transport.

A computerized chart recorder is revealed, comprises a signal conversion unit, an operation control unit, a printing control unit, and a database. A signal conversion unit receives measurement signals of a measurement instrument, and converts the measurement signals to signal conversion data. A operation control unit receives the signal conversion data required for printing, produces corresponding chart data, and prints the curve of signal variations, which can be also displayed on a human-machine interface unit. Whether to store the data or to print can be determined. Besides, the data can be also transmitted to a printing control unit. When the printing control unit is activated, it can receive the chart data and the quality assurance data, and control a printing unit to emulate the chart recorder for executing chart recording. In addition, the quality assurance data can be printed as well for complying with the requirements of the quality-assurance operations.
