Abstract

The Shockley-Queisser (S-Q) model sets a theoretical limit on the power conversion efficiency (PCE) of single-junction solar cells at around 33%. Recently, a PCE of 50%-60% was achieved for the first time in n-type single-junction Si solar cells by inhibiting light conversion to heat at low temperatures. Understanding these new observations opens tremendous opportunities for designing solar cells with even higher PCE to provide efficient and powerful energy sources for cryogenic devices and outer and deep space explorations.

光伏电池超越Shockley-Queisser效率极限。

Shockley-Queisser （S-Q）模型将单结太阳能电池的功率转换效率（PCE）的理论极限设定在33%左右。最近，在n型单结硅太阳能电池中，通过在低温下抑制光转化为热，首次实现了50%-60%的PCE。了解这些新的观测结果为设计具有更高PCE的太阳能电池提供了巨大的机会，为低温设备和外太空和深太空探索提供了高效和强大的能源。

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.
