We demonstrate the implementation of a hybrid solar cell that comprises a surface nanostructured n-type Si and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate). The Si surface before deposition of the organic layer was nanostructured by using CsCl self-assembled nanoparticles as a hard mask and dry etching to form radial junction architectures and enhance light diffusion and absorption. Apart from the textured Si surface, processing parameters such as from metal-electrode shadow ratio, spin-coating rate, and surfactant addition were properly adjusted to improve overall cell performance. Our hybrid solar cells achieve the best performance under optimized cell parameters with a power conversion efficiency of 8.84% and short-circuit current density of 30.5 mA/cm(2). This combined technique provides a simple, scalable, and cost-effective process for fabricating hybrid solar cells.
我们展示了一种混合太阳能电池的实现，该电池由表面纳米结构的 n 型硅和聚（3,4-乙二氧基噻吩）：聚（苯乙烯磺酸盐）组成。在沉积有机层之前，使用 CsCl 自组装纳米颗粒作为硬掩模和干法刻蚀来形成径向结结构，以增强光的扩散和吸收，对 Si 表面进行纳米结构化。除了具有纹理的 Si 表面之外，还适当调整了诸如金属电极遮挡比、旋涂速率和表面活性剂添加等处理参数，以提高整体电池性能。我们的混合太阳能电池在优化的电池参数下实现了最佳性能，功率转换效率为 8.84%，短路电流密度为 30.5 mA/cm(2)。这种组合技术为制造混合太阳能电池提供了一种简单、可扩展且具有成本效益的工艺。
