摘要

户外和偏远地区的能源供应问题已成为一项重大挑战。太阳能自给式锌空气充电电池（RZABs）为离网地区提供了一种可行的能源解决方案。然而，对于太阳能发电系统和 RZABs 系统的技术兼容性和适应性，以及这种太阳能供电 RZABs 系统的能量转换和储存效率，还没有专门的研究。为了应对这些挑战，本研究开发了一种基于光响应聚噻吩（pTTh）阴极的太阳能自持光辅助 RZABs 系统。该系统采用具有光响应特性的 pTTh 作为 RZABs 阴极催化剂，不仅显著降低了阴极的过电位，还提高了 RZABs 的性能和整体能量转换效率（达到 16.2%）。在实际应用中，该系统表现出卓越的稳定性，可在 -15 至 40°C 的宽温度范围内连续运行，并具有长达 33 天的稳定循环运行能力。它为手机、手电筒、全球定位系统和小型污染物检测系统等电子设备提供了可靠、低成本的电力支持，大大提高了这些设备在离网地区的实用性。

High energy conversion efficiency and cycle durability of solar-powered self-sustaining light-assisted rechargeable zinc–air batteries system

The issue of energy supply in outdoor and remote areas has become a significant challenge. Solar-powered self-sustaining rechargeable zinc-air batteries (RZABs) offer a viable energy solution for off-grid regions. However, there has been no specific study on the technical compatibility and adaptability of the solar power generation system and RZABs system, as well as the efficiency of energy conversion and storage in such solar-powered RZABs systems. To address these challenges, this study developed a solar-powered self-sustaining photo-assisted RZABs system based on a photo-responsive polyterthiophene (pTTh) cathode. This system employs pTTh with photo-responsive properties as the cathode catalyst for RZABs, which not only significantly reduces the overpotential of the cathode but also enhances the performance of the RZABs and the overall energy conversion efficiency (reaching 16.2 %). In practical applications, the system exhibits excellent stability, operating continuously within a wide temperature range of -15 to 40 °C, and demonstrating a stable cycling operation capability of up to 33 days. It provides reliable, low-cost power support for electronic devices such as mobile phones, flashlights, GPS units, and small pollutant detection systems, greatly improving the practicality of these devices in off-grid areas.
