Abstract:
An interactive photovoltaic device and an interactive photovoltaic system are provided. The interactive photovoltaic device communicates with a mobile device without any external power and battery. The mobile device has a display panel. The interactive photovoltaic device includes a case, a solar panel, an optical signal receiver and a control circuit. The solar panel is disposed on a first area of a bottom of the case. The optical signal receiver is disposed on a second area of the bottom of the case. When the mobile device executes interactive software and the interactive photovoltaic device is disposed on the display panel of the mobile device, the interactive photovoltaic device receives display panel light through the solar panel to enable the control circuit, and the control circuit receives an optical signal through the optical signal receiver, and decodes the optical signal to obtain an interactive instruction inputted by a user.
