In this article, we simulated the performance of bifacial and monofacial silicon heterojunction solar cells under measured spectro-angular solar irradiance. We developed a new set-up and procedure to measure spectro-angular irradiance over a wide range of orientations. Measurements were executed in Enschede, the Netherlands (${52^\circ }{23^{\rm{'}}}\ $N,${\rm{\ }}{6^\circ }{85^{\rm{'}}}\ $E). Using this measured multi-dimensional input irradiance along with SunSolve simulated external quantum efficiency for various cells, we determined the short-circuit current density of bifacial and monofacial silicon heterojunction solar cells. We conclude that monofacial cells perform marginally better than bifacial cells for front-side illumination (up to 3.0% more for direct sun) and bifacial cells perform significantly better than monofacial cells (higher output ranging from 20.1% to 68.1%), under diffuse irradiance. We compared our results with a well-monitored roof-top solar module set-up and found good agreement for clear sky days (accuracy 1.1%–8.5%).

在测量的分光角太阳辐照度下模拟双面和单面硅太阳能电池短路电流密度

在本文中，我们模拟了在测量的分光角太阳辐照度下双面和单面硅异质结太阳能电池的性能。我们开发了一种新的设置和程序来测量各种方向的光谱角辐照度。测量在荷兰恩斯赫德进行（${52^\circ }{23^{\rm{'}}}\ $否，${\rm{\ }}{6^\circ }{85^{\rm{'}}}\ $E)。使用这种测量的多维输入辐照度以及 SunSolve 模拟的各种电池的外部量子效率，我们确定了双面和单面硅异质结太阳能电池的短路电流密度。我们得出的结论是，在漫射辐照度下，单面电池的正面照明性能略好于双面电池（阳光直射时高 3.0%），双面电池的性能显着优于单面电池（更高的输出，范围为 20.1% 至 68.1%） . 我们将我们的结果与监控良好的屋顶太阳能模块设置进行了比较，发现晴天的情况非常吻合（准确度为 1.1%–8.5%）。
