Abstract
A curved photovoltaic member includes a power generation layer, a current transmission layer, a front plate, and a back plate. The current transmission layer is located at a second side of the power generation layer and is electrically connected to the power generation layer. The front plate is located at a first side of the power generation layer. The back plate is located at a side of the current transmission layer away from the power generation layer.
