We have fabricated and characterized the performance of carrier selective molybdenum oxide (MoO x )/n-Si heterojunction solar cells (HSCs), with the MoO x prepared by both E-beam evaporation (e-MoO x ) and solution process (s-MoO x ) techniques. The s-MoO x /Si HSC demonstrates the best power conversion efficiency of 12.5 %, with an open circuit voltage of 555 mV, short circuit current density of 33.3 mA cm −2 , and fill factor of 67.4% and it is higher than the efficiencies reported to date for s-MoO x /Si HSC. The efficiency achieved is approaching the 13.3% obtained for the e-MoO x /Si HSC. The slightly lower efficiency of s-MoO x /Si HSC is attributed to its carrier extraction loss arising from a higher contact resistivity at the MoO x /n-Si interface. This is also reflected in the selectivity of the contacts, which measures 10.1 for the s-MoO x contact, relative to 11.5 for ...

载流子选择性溶液处理的氧化钼硅异质结太阳能电池的效率超过12％

我们已经制造并表征了载流子选择性氧化钼（MoO x）/ n-Si异质结太阳能电池（HSCs）的性能，并通过电子束蒸发（e-MoO x）和固溶过程（s- MoO x）技术。s-MoO x / Si HSC的最佳功率转换效率为12.5％，开路电压为555 mV，短路电流密度为33.3 mA cm -2，填充系数为67.4％，高于迄今为止报道的s-MoO x / Si HSC效率。对于e-MoO x / Si HSC，获得的效率接近获得的13.3％。s-MoO x / Si HSC的效率稍低，归因于其在MoO x / n-Si界面处较高的接触电阻率引起的载流子提取损失。这也反映在触点的选择性上，该度量为10。
