Abstract

Mg2+ ion based self-charging prototype polymeric photo-power cell has been developed in a very simple and inexpensive way. Eosin Y/MgCl2/PVA mixed aqueous solution and poly(lactic acid) /polyvinylidene fluoride (3:1) composite film are the main assembling components of the device responsible for photo-electrons generation and storage. According to the study of the photovoltaic performance of the cell, a maximum of ∼1 V is obtained under the light intensity of ∼110 mW/cm2. The storage capacity of the device is evaluated to be ∼4.0 F/m2 with an energy density of ∼0.6 mWh/m2 and a power density of ∼2. 5 W/m2 by analyzing the charging–discharging data of the power cell. The charging–discharging data are also recorded for 20 cyclic performances (one cycle per day) to check the longevity of our fabricated Mg2+ ion system. A series connection of four devices can be used as a photo-power bank, which is able to lightened up commercially available 18 LEDs with high intensity, which ensures practical utilizations.

基于聚乳酸/聚偏二氟乙烯薄膜的光充镁离子电池

以 Mg2+ 离子为基础的自充电聚合物光电池原型以非常简单和廉价的方式研制成功。Eosin Y/MgCl2/PVA 混合水溶液和聚乳酸/聚偏氟乙烯（3:1）复合薄膜是该装置负责产生和储存光电子的主要组装元件。根据对该电池光伏性能的研究，在光照强度为 110 mW/cm2 的条件下，该电池的最高电压可达 1 V。根据能量密度为 ∼0.6 mWh/m2 和功率密度为 ∼2.5 W/m2 的功率密度。此外，还记录了 20 次循环（每天一次）的充放电数据，以检验我们制造的 Mg2+ 离子系统的使用寿命。四个装置的串联可用作光电库，能以高强度点亮市售的 18 颗 LED，从而确保了实用性。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
