Abstract
A touch panel and a touch display device are disclosed. The touch panel includes a base substrate and a touch electrode layer and a transparent thin film photovoltaic cell disposed on the base substrate. The touch electrode layer and the transparent thin film photovoltaic cell are superimposed to each other and disposed on the same side of the base substrate, and a transparent insulating layer is disposed between the touch electrode layer and the transparent thin film photovoltaic cell; or the touch electrode layer and the transparent thin film photovoltaic cell are respectively disposed on either side of the base substrate; and the transparent thin film photovoltaic cell includes an n-doped graphene layer and a p-doped graphene layer. The transparent thin film photovoltaic cell disposed in the touch panel can charge an electronic product so that the service time of the touch panel can be prolonged.
