摘要

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。

Surpassing Shockley–Queisser Efficiency Limit in Photovoltaic Cells

Highlights

A record power conversion efficiency of 50%–60% was achieved in Si solar cells by inhibiting the lattice atoms’ thermal oscillations at low temperatures.
Enhancing the light penetration depth can effectively mitigate carrier freeze-out and expand the operational temperature range of silicon cells to 10 K.

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.
