摘要
本文介绍了交错背接触IBC太阳能电池的制备和电学特性。这些太阳能电池是专门为加泰罗尼亚理工大学(UPC)正在开发的基于CubeSat的卫星设计的。太阳能电池包括一个透明的覆盖玻璃作为地外辐射屏蔽。采用表面复合速度<;在最终设备上有100 CMLS。测量结果证实，在开路电压Voc ~650 m V和短路电流密度Jsc ~25 mA/cm2下，光伏效率η′s ~ 12%。一个由11个IBC太阳能电池串联连接的模块将集成在卫星的一个面，形成电源子系统的一部分。初步结果证实该模块具有良好的电气性能。
In this work the fabrication and electrical characterization of interdigitated back contact IBC solar cells is shown. These solar cells have been specifically designed for a CubeSat based satellite under developement at the Universitat Politecnica de Catalunya (UPC). Solar cells incorporate a transparent cover-glass as an extraterrestrial radiation shield. Front surface passivation was achieved using an Al2O3 layer exhibiting surface recombination velocities <; 100 cmls at the final device. Measurements confirm photovoltaic efficiencies η's-12%, with open circuit voltages Voc's ~650 m V and short circuit current densities Jsc's ~25 mA/cm2. A module with 11 IBC solar cells interconnected in series will be integrated in one of the faces of the satellite forming part of the power subsystem. Preliminary results confirm the good electrical performance of the module.
