Abstract

A double-sided light-transmitting cadmium telluride solar cell and a preparation method therefor. By means of FTO transparent conductive glass (1) and an NTO transparent conductive layer (4), double-sided light transmission by the CdTe solar cell can be realized, such that the light energy utilization rate, photoelectric conversion rate and power generation capacity of the CdTe solar cell can be improved. After the fluorine in an FTO transparent conductive layer replaces some of the oxygen in tin oxide, an n-type semiconductor is formed, and after the nitrogen in the NTO transparent conductive layer (4) replaces some of the oxygen in tin oxide, a p-type semiconductor is formed, such that by means of doping tin oxide, the corresponding carrier concentration can be increased, thereby improving the conductive performance of the tin oxide. The NTO transparent conductive layer (4) is prepared by means of a magnetron sputtering method, which is simple and can be achieved merely by modifying the existing metal electrode production equipment in a simple way, and therefore, the method has a relatively strong applicability.

Abstract

The present invention provides a cadmium telluride solar cell and a preparation method thereof. The method comprises: providing a substrate layer, and forming a window layer on a first surface of the substrate layer, wherein the material of the window layer comprises magnesium-doped zinc oxide; forming a light absorption layer on a surface of the window layer, wherein the light absorption layer comprises a cadmium selenide/selenium-doped cadmium telluride/cadmium telluride composite layer; and forming a back electrode layer on a surface of the light absorption layer. The cadmium selenide/selenium-doped cadmium telluride/cadmium telluride composite layer structure maximizes absorption of long-wavelength light and short-wavelength light performed by the solar cell, increases short-circuit current density of the cell, and improves the efficiency of the cell. The window layer of the solar cell is made from magnesium-doped zinc oxide, and serves as a buffer layer, thereby reducing recombination of carriers between interfaces. The cadmium selenide/selenium-doped cadmium telluride/cadmium telluride composite layer having a selenium-doped gradient effectively prevents diffusion of copper ions into the magnesium-doped zinc oxide window layer, thereby reducing generation of deep-level defects, and improving initial performance and long-term stability of the solar cell.

Abstract

A main drive control method for glass factories, comprising the following steps: (a) providing a first circuit breaker and a second circuit breaker on a power supply loop of an electrical motor, wherein one end thereof is respectively connected to two main drive electrical motors; (b) enabling the first circuit breaker to be connected to a municipal power supply and the second circuit breaker to be connected to a UPS power supply; and (c) enabling the first circuit breaker and the second circuit breaker to be interlocked via a mechanical interlocking mechanism, so that only one of the circuit breakers can be switched on during a normal operation. The main drive control method for glass factories solves the problem that the rotation speed of a main drive electrical motor is incorrect due to the interference on a signal. The requirement of no stop of both electrical motors when either a municipal power supply or a UPS power supply has a failure is met; and meanwhile, the two main drive control systems are respectively provided with an independent control box, thereby avoiding a man-made accident when either of these has a failure or is repaired.

Abstract

A large melting furnace suitable for borosilicate glass. The large melting furnace is provided with a melting area, a reinforcing area, an ascending area and a clarifying area. The melting area and the reinforcing area are separated by a partition wall, and the lower end of the partition wall goes deep below a molten glass level but does not contact the tank bottom of the melting furnace, so that the molten glass in the two areas is communicated with each other. The problem of boron volatilization of the borosilicate glass in the melting process caused by flame melting can be alleviated by means of the structures of the melting area and the reinforcing area. The molten glass flows out of a throat in the reinforcing area, passes through the ascending area and enters the clarifying area with smaller tank depth. By means of a homogenization device arranged in the ascending area and an electric heating and negative pressure system arranged in the clarifying area, the molten glass is sufficiently homogenized and clarified.

Abstract

The invention relates to a method for conditioning the CdTe layer of CdTe thin-film solar cells without the use of CdCl2. Calcium tetrachlorozincate (CaZnCl4) is to be used instead of CdCl2 for activation, and the process parameters that have proven themselves over time are to be kept. The method involves the activation of the CdTe layer of semi-finished thin-film CdTe solar cells; calcium tetrachlorozincate is applied to the CdTe layer (4) and the semi-finished thin-film CdTe solar cell subsequently undergoes a heat treatment. The calcium tetrachlorozincate layer is preferably applied via methods from the prior art, for instance roller coating with an aqueous or methanolic salt solution, spraying on an aqueous or methanolic salt solution, an aerosol coating or a dipping bath.

Abstract

An isothermal drop speed cooling method of the forced convection area of a lier and an apparatus for same. A glass ribbon carried with glass passes through the forced convection area of the lier, and the glass ribbon is moving while the glass is being air-cooled in the forced convection area. The glass is air-cooled by different air volume according to the temperature of the glass, so that the glass is allowed to be cooled at isothermal drop speed during the moving process of the glass. According to the cooling method and apparatus, the specification size of the opening section of multi-row air nozzles longitudinally arranged is increased along the traveling direction of the glass ribbon, so that the cooling air volume from the front to the back can be gradually increased, thereby allowing the temperature drop speed of a glass plate to be uniform from the front to the back. The cooling method improves the phenomenon of that the cooling speed of the traditional glass ribbon is high at the front and low at the back.

Abstract

The present invention refers to a method for producing CdTe thin-film solar cells,respectively a semi-finished CdTe thin-film solar cell, where in an additional temperature step is carried out after applying the CdTe layer on to a substrate.In particular, the temperature step is performed after activating the CdTe layer using a suitable activation agent and removing the residual activation agent from the CdTe layer. The temperature treatment is performed under vacuum or in a heating chamber filled with either air or inert gas, during which treatment the substrate is exposed to a temperature between 180°C and 380°C for a time between 5 minutes and 60 minutes. Due to the inventive additional temperature step, the number and extension of crystal defects in the CdTe layer is reduced and the electric efficiency of the solar cell is further improved.

Abstract

A method for recycling thin-film solar cell modules which are which are composed of a substrate layer with a superimposed structure of functional layers, a plastic layer that encapsulates the functional layers, and a cover layer. The substrate layer is transparent to a working laser beam, and the first functional layer, an electrode layer, is able to absorb this working laser beam. The free surface of the substrate layer is scanned with the working laser beam so that the first electrode layer, due to having absorbed the working laser beam, is at least partially vaporized and the superimposed structure of the functional layers is thus detached from the substrate layer. The substrate layer, separately from the functional layers that are attached to the plastic layer and the cover layer, is subsequently available for separate further processing.
