High quality carrier-selective contacts provide not only a low carrier recombination at both contact and non-contact regions,but also allow an effective and simple one-dimensional current flow pattern in the substrate with a low contact resistivity,resulting in high efficiency for crystalline silicon solar cells.In this work,we present a novel and high performance TiO2-based electron selective contact for crystalline silicon solar cells.A high efficiency of 21.6% is achieved for a simple silicon solar cell featuring a full-area TiO2-based electron selective contact.Thin TiO2 film is demonstrated to provide not only high quality surface passivation to silicon surfaces,but also allow a moderate contact resistivity at the Si/TiO2 heterojunction.This work suggests a potential strategy to achieve high efficiency silicon solar cells with a simple and low-cost transition metal oxide based carrier-selective contacts.

世界各地气象部门几乎都只能提供水平面辐照量，而要把这些数据换算成所设计的光伏方阵的倾斜面辐照量，则必须掌握当地各倾斜面辐照量与水平面辐照量的比值。笔者经过多年连续不断的监测、收集和整理，得出上海地区的5°/0°、10°/0°、15°/0°、20°/0°和25°/0°的年辐照量比值。并通过研究相近纬度地区的各月辐照量，模拟出了不同辐照量等级下的比值函数式，谨供相近纬度地区的光伏科研和工程设计人员参考
