| 1 | Enhancement of photoelectrochemical performance in ferroelectric films via the introduction of an Au buffer layer显示文摘The inefficient separation of photogenerated carriers has become a serious problem that limits the photoelectrochemical(PEC)performance of semiconductors.Herein,a sol-gel method was used to prepare BiFeO_(3) ferroelectric thin films with FTO and FTO/Au as substrates,respectively.The polarization electric field of the ferroelectric can more effectively separate the carriers generated in the photoelectrode.Meanwhile,the introduction of an Au buffer layer can reduce the resistance in the process of charge transfer,accelerate the carrier migration,and enhance the efficiency of the charge separation.Under light irradiation,Au/BiFeO_(3) photoelectrode exhibited an extraordinary improvement in PEC water splitting compared with BiFeO_(3).In addition,the ferroelectric polarization electric field causes band bending,which further accelerates the separation of electrons and holes and improves the PEC performance of the photoelectrode.This work promotes the effective application of ferroelectric films in PEC water splitting. | Dawei Cao Ming Li Jianfei Zhu Yanfang He Tong Chen Yuan Liu Mingming Chen Ying Yang | 2021 | Journal of Semiconductors2021，42，11： | 1 |
| 2 | SE掺杂技术对M10单晶PERC电学性能的影响显示文摘选择目前市场主流的M10单晶PERC作为研究对象,就PERC生产技术中较为通用的SE掺杂技术进行分析。通过调整SE掺杂技术中的激光划线速度及激光功率参数,对各组别硅片和电池的性能参数进行测试和数据分析。针对激光划线速度分析了参数变化对硅片方块电阻的影响,并对最终电池性能参数进行了验证。通过调整激光功率,验证方块电阻的变化,并通过ECV测试分析不同功率下掺杂浓度随结深的变化趋势,对应效果在电学性能测试中也有体现。 | 贾艳飞 | 2022 | 能源与节能2022，，12： | 0 |
