Description
Technical field
The utility model designs computer accessories field more particularly to a kind of surrounding with cadmium telluride diaphragm solar battery
Keyboard.
Background technique
With the development of science and technology, the popularity of computer is higher and higher, and people's lives and work are also more next
More too busy to get away computer has many people due to working or entertaining etc. to for a long time using computer daily, while also from not
It opens and keyboard is operated with, and existing keyboard is powered by power supply line external power supply or internal battery on the market
, it is both not convenient enough or not environmentally friendly enough so to use, do not meet the theory of energy-saving and emission-reduction, if the battery replaced with
Meaning abandons and also easily causes serious environmental pollution.
Utility model content
Keyboard the main purpose of the utility model is to provide a kind of surrounding with cadmium telluride diaphragm solar battery, with solution
Certainly common keyboard is using needing external power supply or internal battery not to meet energy-saving and emission-reduction theory, easily cause asking for environmental pollution
Topic.
To achieve the goals above, the utility model provides a kind of sterilization keyboard, including keyboard body and around keyboard
The cadmium telluride diaphragm solar battery that ontology is circumferentially arranged, the cadmium telluride diaphragm solar battery include transparent glass substrate with
And it is coated in the cadmium telluride photovoltaic material coating in transparent glass substrate.
Further, the cadmium telluride photovoltaic material coating is with a thickness of 4 microns.
Further, the cadmium telluride photovoltaic material coating be divided into from the inside to the outside on transparent glass substrate surface tco layer,
CdS Window layer, CdTe absorbed layer and back contact.
Further, PCBA circuit board is equipped in the keyboard, the PCBA circuit board passes through FPC flexible board and the tellurium
The connection of cadmium thin-film solar cells.
Further, the upper marginal position of the keyboard body is provided with LED light, the LED light with it is described
The connection of PCBA board circuit plate.
Compared with the prior art, the advantages of the utility model are: being surrounded by cadmium telluride diaphragm solar electricity in keyboard
Pond can be carried out stable and efficient photoelectric conversion, to substitute the mode of conventional batteries power supply, more energy efficient environmental protection meets section
The theory of energy emission reduction can efficiently solve traditional wire keyboard using not convenient enough and replacement battery and easily cause environmental pollution
Problem.

Specific embodiment
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The utility model embodiment as shown in Figure 1 includes keyboard body 1, and around the circumferential setting of keyboard body 1
A cadmium telluride diaphragm solar battery 2.
Specifically, as shown in Figures 2 and 3, cadmium telluride diaphragm solar battery 2 includes a transparent glass substrate 20, main
To play bracket to entire battery, prevent pollution and incident sunlight, cadmium telluride light is coated in transparent glass substrate 20
Electric material coating 21, cadmium telluride photovoltaic material coating 21 be respectively with a thickness of 4 microns and from the inside to the outside tco layer, CdS Window layer,
CdTe absorbed layer and back contact: tco layer, that is, oxidic, transparent, conductive layers, what is mainly served is light transmission and conduction；CdS window
Layer is n-type semiconductor, forms p-n junction with p-type CdTe；CdTe absorbed layer is the main body light-absorption layer of battery, the CdS window with N-shaped
The p-n junction that layer is formed is the most crucial part of entire battery；Contact of the back contact mainly for reduction CdTe with metal electrode
Potential barrier, extracted current make metal electrode and CdTe form Ohmic contact.It is equipped in keyboard body 1 and controls entire keyboard work electricity
The PCBA circuit board 3 on road, PCBA circuit board 3 are connected with cadmium telluride diaphragm solar battery 2 by FPC flexible board 4, cadmium telluride
Thin-film solar cells 2 realizes that specific photoelectric conversion makes PCBA circuit board 3 be powered to keyboard sheet in the case where illumination
Body 1 is powered.The upper marginal position of keyboard body 1 is additionally provided with LED light 5, and LED light 5 and PCBA circuit board 3 is electrically connected
It connects, user can show situation to recognize cadmium telluride diaphragm solar battery 2 and key by the light of LED light 5
The working condition of disk ontology 1.
Such keyboard optoelectronic transformation efficiency with cadmium telluride diaphragm solar battery 2 is up to 17.8% and performance is stablized, complete
Conventional batteries can be substituted entirely, and uninterrupted power supply, entire power supply process energy conservation and environmental protection are carried out to keyboard.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention, all institutes within the principle of the utility model
Any modification, equivalent substitution, improvement and etc. of work, should be included in the protection scope of the utility model.
