A crystalline silicon (c-Si) based PV module comprised of 25 mini c-Si solar cells in series connection was employed to charge a solid-state lithium-ion batteries in a monolithic integrated device . The Si-based photobattery exhibited a rapid photo-charging process in less than 2 min with an overall efficiency of 7.61%.
Operation mechanism of a solar battery. (a) In a solar battery the solar cell functionality can either operate in parallel (IEC) or in series (VEC) to the battery and power supply/consumer (PSU).
Provided by the Springer Nature SharedIt content-sharing initiative Two-electrode solar rechargeable device is one of the promising technologies to address the problem of solar energy storage in large scale. However, the mechanism of dark output voltage remains unclear and the low volumetric energy density also limits its practical applications.
These results offer guidance to improve the performance of a solar rechargeable device and design other photoelectric devices for new applications. A Faradaic junction solar rechargeable device is one of the promising technologies to address the problem of solar energy storage but the working mechanism remains unclear.
Solar batteries present an emerging class of devices which enable simultaneous energy conversion and energy storage in one single device. This high level of integration enables new energy storage concepts ranging from short-term solar energy buffers to light-enhanced batteries, thus opening up exciting vistas for decentralized energy storage.
