1. Introduction to the Project
1.1 Project background
1.1.1 Product introduction
Cadmium telluride power generation glass, with a wide range of applications and very typical glass building material characteristics, is a new type of “power generation glass” building materials, suitable for residential construction industry. Cadmium telluride thin-film solar cells are significantly lower than crystalline silicon and other materials in terms of production cost of solar cell technology, and secondly, they are the most consistent with the sun's spectrum, absorbing more than 95% of sunlight. With standard process and low energy consumption, it can be recycled after the end of the life cycle, can generate electricity both in strong and weak light, and the higher the temperature, the better the performance.
This product is located in Pingxi Township, Tiexi District, Siping City for building a cadmium telluride power generation glass project. The building materials of photovoltaic products are of strategic significance for the application of photovoltaic green buildings, and at the same time promote the high-quality development of green transformation in the region and even the province.
1.1.2 Market prospect
(1) The development status of cadmium telluride power generation glass
In recent years, the technology of solar cells has been extremely popular, and there are currently four mainstream materials, namely polycrystalline silicon thin films, amorphous silicon thin films, copper indium gallium selenide (CIGS) polycrystalline films and cadmium telluride (CdTe) polycrystalline films. Cadmium telluride (CdTe) is an important II.-VI compound semiconductor material, the shape of which is black crystal particles or powders, with a melting point of 1,092°C, a relative molecular weight of 240, and a crystal structure of sphalerite type with a direct transition band structure. Its lattice constant is 0.6481nm, the band gap is 1.45eV, the room temperature electron mobility is 1,050 c㎡/(Vs), and the room temperature hole mobility is 80 c㎡/(Vs).
The bond energy of cadmium telluride chemical bonds is as high as 5.7 eV, which is one of the most stable chemical states of cadmium in nature. Therefore, cadmium telluride is chemically stable at room temperature, insoluble in water and weak acid, and is relatively safe in industrial production and use, and is widely used in semiconductor materials in the field of optoelectronics, especially in the manufacture of solar cells. Cadmium telluride thin-film modules are environmentally friendly. Taking cadmium emissions as an example, the cadmium emissions of amorphous silicon thin-film cells on the heavy metal emission index table are much lower than those of fossil fuels such as oil and coal that can be used for energy by combustion, and are similar to those of natural gas. Whether in the production or use process, it is safe and controllable. Due to its unique physical and chemical properties, cadmium telluride excels in the photovoltaic field and has become an important part of the photovoltaic industry. In addition, cadmium telluride is also widely used in other fields, such as infrared detectors, nuclear radiation detectors and other fields.
(2) Prospect analysis of cadmium telluride glass
Under the same light conditions, cadmium telluride power generation glass exhibits higher energy conversion efficiency than traditional silicon solar cells. This shows that cadmium telluride power generation glass can produce more electricity at the same light intensity.
Cadmium telluride power generation glass with excellent flexibility can easily adapt to various curved and irregular surfaces, so it is widely used in many fields such as construction, automotive, aerospace and so on. With a service life of more than 25 years, it far exceeds that of traditional silicon solar cells, providing investors with more lasting returns.
Cadmium telluride power generation glass is not only used for roofs and windows in the field of building energy efficiency, but also expands to emerging markets such as mobile energy and distributed power stations. With the increasing popularity of new energy vehicles, their application prospects in car windows and on-board energy are also broad.
Technological breakthroughs have enabled remarkable achievements in the large-scale production of cadmium telluride power generation glass. In August 2017, CNBM (Chengdu) Optoelectronic Materials Co., Ltd. successfully manufactured the world's first large-area (1.92 square meters) cadmium telluride power generation glass, marking China's leading position in this field. At the same time, with the continuous advancement of production technology, the photoelectric conversion efficiency is also improving, and the average efficiency of commercialized modules is about 18%.
With the growth of global demand for renewable energy and the government's support for new energy policies, the market potential of cadmium telluride power generation glass is huge. Technological advancements and cost reductions will also further enhance its competitiveness in the market.
In summary, with the advantages of high energy conversion efficiency, durability and high flexibility, cadmium telluride power generation glass has a wide range of application potential in the fields of construction, mobile energy and distributed power stations. With the continuous development of technology and policy support, its market prospects are very promising.
