Then we studied the effect of junction uniformity on the aluminum - alloyed back surface field to solar cell performance . the formation theory of aluminum - alloyed back surface field , the effect parameters to the doping concentration and the junction depth were analyzed 比较了两种商业太阳电池的杂质浓度分布及结深情况;叙述了铝背场的作用及形成原理,对影响铝背场表面浓度和结深的参数作了分析。
The pc id has been used in order to analyse the influence of surface recombination on the performance of crystalline silicon solar cell . in different surface concentration , the relation of the surface recombination velocity and the performance ( voc , jsc , g ) of crystalline silicon solar cell is discussed 采用pc1d就表面复合对太阳电池性能的影响进行理论计算,探讨了晶体硅太阳电池不同表面浓度条件下,表面复合速度与太阳电池开路电压、短路电流以及转换效率之间的关系。
From then on , the above two shortcomings had been overcome . impurity concentration and junction depth can be accurately controlled and freely adjusted . both low and high dopant concentration can be gained easily , and ideal distribution of ga in si can also be achieved with uniform surface concentration , good repeatability and high eligibility and excellence ratio , which have greatly improved comprehensive performances of the devices 此工艺发明以来,克服了上述两者的弊端,杂质浓度和结深能准确控制而又能任意调整,可进行低、高浓度阶段性掺杂,得到元素ga在si中的理想分布,而且表面浓度均匀一致、重复性好、合格率和优品率高,改善和提高了器件的综合性能。
On the base of these theory calculations , we passivated the front - surface both of different surface doping concentration solar cells by a thin layer of thermally grown sio2 . the results show that the in heavy surface doping concentration cell is lower compared to the cell in light surface doping concentration . the majority of improvement in comes from the emitter surface passivation 接着采用sio2作为钝化膜,从实验上比较了在不同表面浓度下单晶硅太阳电池的钝化效果,结果表明在高表面浓度下其开路电压比低表面浓度下的开路电压低,这开路电压的提高主要来源于降低了前表面复合。
