Abstract
A combined solar recharging thin-film charge storage device and a method of its manufacture, wherein charge generation and storage are achieved within the same multilayer stack by providing a layer which functions as a photoactive layer and at the same time comprises ions towards which it is ion-permeable and separates physical contact between two electrodes. Accordingly, a simple device structure is provided which may be manufactured easily and cost-efficiently and which allows easy integration with other components.
Claims15
