Embodiment 1

[0026] This embodiment discloses a mobile phone solar cell compensation structure by taking a straight mobile phone without a camera on the back shell as an example. The back shell is close to the battery electrodes of the mobile phone, and is located on both sides of the shell to penetrate the shell and integrate with the shell. The lead-out electrodes are flush with the shell surface on the outside of the shell, and inside the shell Connect with the mobile phone battery electrode to form a loop. Amorphous silicon thin-film solar cell units connected in an inline or outboard structure are arranged on the surface of the housing. An anti-reflection film layer is provided above the thin-film solar cell unit.

[0027] When the back shell of the mobile phone is exposed to light, the amorphous silicon thin-film solar cell absorbs the light to generate electricity, and the electric energy flows to the battery of the mobile phone through the lead-out electrodes to supplement the con...

Embodiment 2

[0029] This embodiment discloses a mobile phone solar cell compensation structure by taking a flip phone with a camera on the back shell as an example. On the back shell surface where there is no camera and the battery of the mobile phone is installed, a lead-out electrode that penetrates the shell and is integrated with the shell is located on both sides of the shell. The lead-out electrode is flush with the surface of the shell on the outside of the shell. The inside of the casing is connected with the electrode seat of the mobile phone battery to form a loop, and a bypass diode is arranged beside the two lead-out electrodes, and the bypass diode and the lead-out electrodes form a path. CIGS thin-film solar cell units connected in an inline or outboard structure are arranged on the surface of the housing. An anti-reflection film layer is provided above the thin-film solar cell unit.

[0030] This embodiment is improved on the basis of the previous embodiment. Because half ...

Embodiment 3

[0032] This embodiment discloses a solar cell compensation structure for a mobile phone by taking the front shell of the netbook as an example. On both sides of the casing, there are lead-out electrodes that penetrate the casing and are integrated with the casing. The lead-out electrodes are flush with the surface of the casing on the outside of the casing, and are connected to the electrode holder of the netbook battery inside the casing. A loop is formed, and a bypass diode is arranged beside the two lead-out electrodes, and the bypass diode and the lead-out electrodes form a path. CIGS stacked thin film solar cell units connected in an inline or outboard structure are arranged on the surface of the casing, and the transparent conductive electrode adopts an ITO film layer. An anti-reflection film layer is provided above it.

[0033] Since the back shell of the netbook generally has many functional small holes, it is not conducive to film formation, and it is also not conduc...

Abstract

The invention discloses a solar cell compensation structure for a mobile phone. The solar cell compensation structure comprises extraction electrodes, a bypass diode, a thin-film solar cell and an anti-reflection thin film, wherein the extraction electrodes are embedded into a mobile phone shell, are externally connected with a positive electrode and a negative electrode of the solar cell, and are connected with a positive electrode and a negative electrode of a mobile phone battery inside the mobile phone shell. The bypass diode is arranged between the extraction electrodes on the shell to prevent reflux of a circuit. A photovoltaic conversion unit of the thin-film solar cell is provided with non-crystalline silicon, non-crystalline silicon lamination, non-crystalline germanium silicon, microcrystalline silicon, non-microcrystalline lamination and CIGS (copper indium gallium selenide. The low-light performance of the thin-film solar cell is made full use of, lost electric energy is compensated for the mobile phone at any time, and the service time of the mobile phone battery can be prolonged. The mobile phone refers to a mobile small electronic product represented by the mobile phone such as an MP3 (moving picture experts group audio layer-3), an MP4 (mobile Pentium 4), an electronic book and a net-book.

Description

technical field [0001] The invention relates to a solar mobile phone battery, and is especially suitable for the field of using solar energy to compensate and charge the battery of mobile small electronic products represented by mobile phones so as to prolong the single use time of the battery. Background technique [0002] The use of solar cells as mobile phone chargers is one of the many applications of solar cells in daily life. It can be easily carried without worrying about being away from the grid, unable to find a suitable socket, etc., and does not need to replace the battery frequently, which is very convenient. [0003] However, due to the limitation of solar cell conversion efficiency, solar mobile phone chargers are often bulky. Compared with smaller and smaller mobile phones with more and more functions, solar chargers are somewhat bulky and inconvenient to carry. [0004] In order to solve the above problems, the present invention utilizes the advantages of wea...
