系统地研究了p型多晶硅太阳电池中基于三氯氧磷（POCl 3）的均匀发射极形成的扩散优化及其与金属接触的相关性。改变沉积温度（810、804、798、792和786摄氏度）以实现通过四点探针测量的不同薄层电阻（85、90、95、100和105欧姆/平方）。发射极质量，金属接触电阻（Rc）和电池性能之间的相关性进行了研究。结果表明，方阻越高，磷表面浓度越低，发射极饱和电流密度越低。电池数据显示，由于来自外部量子效率（EQE）测量的更好的短波长响应，更高的Rsheet导致更高的Voc和Isc，但是由于更高的发射极薄层电阻和与Ag浆料的接触电阻，导致更低的填充因子（FF）。在该测试中，这种类型的Ag浆料（Samsung SDI 8630 A）的最佳Rsheet为90欧姆/平方，最高电池效率为18.325%。(C)2016 Elsevier GmbH.

A systematic investigation of Phosphorus Oxychloride (POCI3) based diffusion optimization for the formation of homogeneous emitters and correlation with metal contact in p-type multi-crystalline silicon (multi-Si) solar cell is presented. The deposition temperature (810, 804, 798, 792 and 786 degrees C) was varied to achieve different sheet resistance (85, 90, 95,100, and 105 ohm/square) measured by four points probes. The correlation between emitter quality, metal contact resistance (Rc) and cell performance was investigated. The results showed, that the sheet resistance is higher, phosphorus surface concentration (Cs) is lower and emitter saturation current density Doe) is lower. The cell data showed that the higher Rsheet result in higher Voc and Isc due to better short wavelength response from the External Quantum Efficiency (EQE) measurement, but lower fill factor (FF) due to higher emitter sheet resistance and contact resistance with Ag paste. The optimal Rsheet for this type of Ag paste (Samsung SDI 8630A) in this test is 90 ohm/square with the highest cell efficiency of 18.325%. (C) 2016 Elsevier GmbH. All rights reserved.
