摘要

碲化钼(MoTe2)具有高效率和较好的热稳定性，是一种具有潜力的光伏(PV)电池。利用AMPS(分析微电子和光子结构)模拟器研究电池性能参数，设计高效超薄MoTe2光伏电池。本研究探讨了在MoTe2光伏电池的背触点金属上插入碲化砷(As2Te3)作为背表面场(BSF)，可以提高电池转换效率。当吸收层厚度为0.9 μm时，As2Te3 BSF的转化效率最高，为25.08%;当吸收层厚度为1 μm时，无BSF的转化效率为17.06%。采用As2Te3 BSF制备的MoTe2光伏电池的热稳定性也较好。

Design of highly stable and efficient molybdenum telluride PV cells with arsenic telluride BSF

For high efficiency and better thermal stability, Molybdenum Telluride (MoTe2) is remarkable as potential photovoltaic (PV) cell. AMPS (Analysis of Microelectronic and Photonic Structures) simulator is used to investigate the cell performance parameters to design the highly efficient ultra-thin MoTe2 PV cell. In this research work, it has been explored that the cell conversion efficiency of MoTe2 PV cell is improved with the insertion of Arsenic Telluride (As2Te3) as back surface field (BSF) above the back contact metal. The highest conversion efficiency of 25.08% was found for As2Te3 BSF with only 0.9 μm of absorber layer whereas it was 17.06% for no BSF with 1 μm thickness of absorber layer. The thermal stability of MoTe2 PV cell with As2Te3 BSF showed better stability also.
