Figures 1 to 3 The diagram shows the structure of the lamp, which includes a housing 1, a circuit board 2 and a rechargeable battery 3 inside the housing 1, a light source 4 on the circuit board 2, and the battery 3 is electrically connected to the circuit board 2 and the light source. A light-transmitting area is provided on the housing 1 corresponding to the position where the light source 4 emits light. In this embodiment, a light guide plate 11 is installed on one side of the housing 1 corresponding to the position where the light source 4 emits light, as a light-transmitting area.

[0026] The outer casing 1 also contains a perovskite photovoltaic panel 5 for converting light energy into direct current. The circuit board 2 is also equipped with a solar controller, which is electrically connected to the perovskite photovoltaic panel 5 and the battery. The solar controller is used to regulate the voltage and current of the direct current generated by the perovskite photovoltaic panel 5 and store it in the battery 3.

[0027] Specifically, the outer shell 1 includes an upper shell 1a, a middle shell 1b, and a bottom shell 1c. For example, the upper shell 1a, the middle shell 1b, and the bottom shell 1c can be made of plastic or metal materials. The bottom shell 1c is fixedly connected to the middle shell 1b by means of snaps, adhesives, screws, or ultrasonic welding to achieve a sealing effect.

The middle shell 1b has a light-transmitting window 11b at the position corresponding to the perovskite photovoltaic panel 5 to allow light to enter. In this embodiment, the entire upper shell 1a is made of a light-transmitting or transparent material. In other embodiments, a light-transmitting or transparent material may only be used at the position corresponding to the light-transmitting window 11b.

[0029] Furthermore, the battery 3 is located between the middle shell 1b and the bottom shell 1c, and the perovskite photovoltaic panel 5 is stacked on the battery 3.
