Abstract

Highlights

Additive-assisted layer-by-layer (LBL) deposition enables organic solar cells to achieve an unprecedented power conversion efficiency of 20.8%, the highest efficiency to date.
The gradient fibrillar morphology enabled by additive-assisted LBL processing promotes the formation of bulk p-i-n structure, improving exciton and carrier diffusion, and reducing recombination losses.
The wrinkle pattern morphology achieved by additive-assisted LBL processing is constructed to enhance the light capture capability.

在有机太阳能电池中采用添加剂辅助逐层加工技术，实现前所未有的接近 21% 的效率

添加剂辅助逐层沉积（LBL）使有机太阳能电池的功率转换效率达到前所未有的 20.8%，这是迄今为止的最高效率。添加剂辅助逐层沉积加工所实现的梯度纤维状形态促进了块状 pi-n 结构的形成，改善了激子和载流子的扩散，降低了重组损耗。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
