The embodiments of the present disclosure relate to the field of photovoltaic module technology, and provide a photovoltaic frame, a photovoltaic module and a method for manufacturing the photovoltaic frame. The photovoltaic frame comprises: a top support portion, a bottom support portion and a transverse edge portion. The top support portion and the transverse edge portion enclose a holding slot, and the top support portion has a bearing surface facing the holding slot. The bottom support portion is arranged opposite to the top support portion, and the transverse edge portion is located at one side of the top support portion away from the bottom support portion. The photovoltaic frame is molded by a carbon steel sheet material after processing.
