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.
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.
