Zusammenfassung: | The invention discloses a preparation method of a silver nanowire grid electrode. The preparation method comprises that a silver nanowire grid layer is prepared on a flexible substrate; sintering electrodes connected to the silver nanowire grid layer are prepared in one pair of opposite sides of the silver nanowire grid layer; and the sintering electrodes are connected to the two ends of a DC power supply respectively to form an electric sintering loop. According to the preparation method, the DC power supply applies a voltage to the sintering electrodes at the two sides of silver nanowire grids, a simple electric sintering technology is used to reduce the contact resistance between silver nanowires and further reduce the resistance of the silver nanowire grids, and the electrical performance of the silver nanowire grid electrodes arranged at random is improved. Compared with a traditional electrode resistance reduction method via high-temperature annealing for long time, the preparation method is simple and effective in technology, low in enforcement cost, high in processing speed, and convenient for large-scale preparation and processing, can meet requirement for a flexible transparent electrode of a photoelectric device at present, and has a wide application prospect. |
