Embodiment 1

[0019] Add 14.3 grams of cuprous oxide and 15.6 grams of aluminum hydroxide into 50 milliliters of polyvinyl alcohol with a concentration of 8 wt % respectively, and then carry out magnetic stirring at room temperature until the two fully dissolve to form a sol respectively; After mixing, perform magnetic stirring to form a precursor sol; then dry the precursor sol at 150°C to form a dry sol; grind the dried sol in an agate mortar and place it in a sintering furnace, and adjust the temperature program from room temperature to The highest temperatures are 1150°C, 1180°C, and 1200°C respectively, and the synthesis is carried out at the highest temperature, and the experimental samples are obtained after annealing. Through the morphology analysis, photoluminescence analysis, and infrared spectrum analysis of the solution and sintered product, it shows that the formation of A sample with high purity and strong transmittance, especially infrared light transmittance, is obtained, so ...

Abstract

The invention discloses a preparing method of CuAlO2 powder adaptable to a solar cell. The method comprises the steps of placing cuprous oxide and aluminum hydroxide into polyvinyl alcohol with a weight ratio of 1:1-4, and carrying out magnetic stirring at the indoor temperature till the two components are fully dissolved to obtain two kinds of sol, wherein the polyvinyl alcohol accounts for 64-78% of the total content; mixing the two kinds of sol and then carrying out magnetic stirring to obtain precursor sol; drying the obtained precursor sol at the temperature of 135-175 DEG C to obtain one kind of dry sol; porphyrizing the obtained dry sol in an agate mortar and then placing the porphyrized dry sol into a sintering furnace to obtain the CuAlO2 powder after annealing. According to the preparing method of the CuAlO2 powder adaptable to the solar cell, pattern analysis, photoluminescence analysis and infrared spectroscopy analysis are carried out on the solution and sinter to confirm that a generated sample is high in purity and high in transmittance, especially infrared light transmittance. Therefore, the preparing method of the CuAlO2 powder adaptable to the solar cell also has a good application prospect in the field of manufacturing of optical devices.

Description

technical field [0001] The invention relates to the field of solar cell processing and manufacturing, in particular to a CuAlO that can be adapted to solar cells 2 Powder production method. Background technique [0002] In the visible region, CuAlO 2 With high transparency and low resistivity, it can be widely used in the fields of solar cells, special material coatings, flat-panel displays and other optoelectronic devices. While the current preparation of CuAlO 2 There are many powder methods, but there are disadvantages such as high requirements for equipment, complicated operation process, high cost, and long experiment cycle. Contents of the invention [0003] The object of the invention is to provide a kind of CuAlO that can be adapted to solar cell 2 The powder preparation method can effectively solve the problems existing in the background technology. [0004] A CuAlO suitable for solar cells 2 Powder production method: [0005] (1) First put cuprous oxide an...
