Abstract
The utility model relates to a small solar array and is characterized in that the utility model is a laminated structure comprising a film, a adhesive film, a solar battery chip and a PCB circuit board, wherein the solar battery chip is arranged between the film and the PCB circuit board, the positive and negative connecting leads of the solar battery chip is arranged on the adhesive film through the PCB board and the film. The utility model is equivalent to a battery, which generates current below 5W; under high temperature and pressure, EVA and PET films are firmly bond with the chip and the PCB board by means of vacuumization, heating and pressurizing processes to protect the solar chip. The utility model has the advantages of firm coherence, long service life (ups to 10 years and above) and extremely low cost.
Description
Technical field
The utility model relates to a kind of solar cell widgets, mainly as little products of power consumption such as Lawn lamp, charger, railway spike lamp, parasol, calculator, flashlight, toys for children, belongs to the solar module technical field.
Background technology
Solar energy widgets in the past adopts series connection, parallel connection solar battery chip on the PCB printed substrate more, produces with some gum forming method after the epoxy resin high temperature melting again.Its rate that manufactures a finished product is lower, and long-time jaundice easily under the irradiation of solar ultraviolet influence attractive in appearance and power output, and useful life is short, generally has only 1-2, and its use cost is very high.
The laminated compenent of solar panel generally all at big assembly, does not also have with respect to the widgets below the 5W now.
Summary of the invention
The purpose of this utility model is below a kind of 5W of invention, the solar cell widgets of long service life.
For realizing above purpose, the technical solution of the utility model provides a kind of solar cell widgets, it is characterized in that, form by glued membrane, adhesive film, solar battery chip, PCB wiring board lamination, solar battery chip is located between glued membrane and the PCB wiring board, the positive and negative connection lead of solar battery chip passes pcb board, and glued membrane is located on the adhesive film.
Described PCB wiring board is composed in parallel by diode and resistance, produces battery current; Described glued membrane is the PET glued membrane; Described adhesive film is the EVA adhesive film.
The utility model is formed a battery with solar battery chip, PCB wiring board; the electric current that is produced is below 5W; employing by vacuumize, heat, pressurize make in the product EVA glued membrane and PET glued membrane under HTHP with chip, firm being bonded together of pcb board; form an integral body, play the effect of protection solar chip.
The utility model has the advantages that:
1. its bonding firmly;
2. long-term use can flavescence;
3. use cost reduces greatly, and useful life is more than 10 years.
Description of drawings
Fig. 1 is a solar cell widgets structural representation;
Fig. 2 is PCB wiring board connection line figure.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be solar cell widgets structural representation, described solar cell widgets is made up of glued membrane 1, adhesive film 2, solar battery chip 3, PCB wiring board 4 laminations.
