Perovskite target material applied to heterojunction and preparation method thereof
The invention discloses a perovskite target material applied to heterojunction and a preparation method thereof, and the preparation method comprises the following steps: adding MoO3 powder and SrCO3 powder into a ball mill, then adding a dispersant, a binder and deionized water, and carrying out ball milling and drying to obtain SrMoO4 powder; putting SrMoO4 powder into a tubular furnace, introducing a reducing gas, and completely reducing the SrMoO4 powder into SrMoO3 powder; carrying out heat treatment on the SrMoO3 powder to obtain precursor powder; performing compression molding on the precursor powder by using cold isostatic pressing equipment to obtain a green body; and carrying out glue removal treatment on the green body, and sintering to obtain the perovskite target material applied to the heterojunction. The perovskite target material applied to the heterojunction has high density and low resistivity, and can improve the photoelectric conversion efficiency and the cell performance when being applied to the heterojunction.
本发明公开了一种应用于异质结的钙钛矿靶材及其制备方法，包括以下步骤：将MoO3粉体、SrCO3粉体加入到球磨机中，再加入分散剂、粘结剂、去离子水，球磨，干燥，得到SrMoO4粉体；将SrMoO4粉体放入到管式炉中，通入还原性气体，将SrMoO4粉体完全还原成SrMoO3粉体；将SrMoO3粉体进行热处理，得到前驱体粉末；将前驱体粉末用冷等静压设备压制成型得到坯体；将坯体进行排胶处理，烧结，得到应用于异质结的钙钛矿靶材。本发明所述的应用于异质结的钙钛矿靶材具有良好的致密度，低电阻率的钙钛矿靶材，应用于异质结，可以提高光电转换效率及电池性能。
