Tin oxide target material for heterojunction battery and preparation method of tin oxide target material
The invention discloses a tin oxide target material for a heterojunction battery. The tin oxide target material comprises tin oxide powder and any one or two of tantalum oxide powder and molybdenum oxide powder; the mass fraction of the tin oxide powder is 94 to 99.5 percent; the particle size of the tin oxide powder is 20 to 80 nm. Doped tantalum oxide and molybdenum oxide are based on the fact that the chemical valence of tantalum (+ 5) or molybdenum (+ 6) is higher than that of tin (+ 2/+ 3), the tantalum (+ 5) or molybdenum (+ 6) enters tin oxide crystal lattices to replace tin in the tin oxide crystal lattices, electron conduction bands are formed, the concentration of free conductive electrons is increased, and then the conductivity is improved; meanwhile, tantalum and molybdenum are high in chemical durability stability, high in thermal stability and good in biocompatibility; meanwhile, the added bentonite is used for adjusting the nano silicon dioxide agent and the flake graphene agent, and the nano silicon dioxide agent and the flake graphene agent are matched and coordinated together, so that the acid corrosion resistance and heat stability resistance of the product are remarkable, and the conductivity, the strength performance and the performance stability of the product are obviously coordinated and improved.
本发明公开了一种用于异质结电池的氧化锡靶材，氧化锡靶材包括氧化锡粉和氧化钽粉、氧化钼粉中的任一种或两种；所述氧化锡粉的质量分数为：94‑99.5%；所述氧化锡粉的粒度为：20‑80nm。本发明掺杂氧化钽、氧化钼是基于钽（+5）或钼元素（+6）的化学价高于锡元素（+2/+3），进入氧化锡晶格中会替代里面的锡，形成电子导带，使得自由导电电子的浓度增加，进而提升导电性；同时，钽与钼的化学耐久稳定性高，热稳定性高，且具有很好的生物相容性；同时加入的膨润土调节纳米二氧化硅剂与片状石墨烯剂，通过二者协配，共同协调，产品的耐酸腐、耐热稳定性效果显著，产品的导电、强度性能以及性能稳定性协调改进明显。
