A Rising Star in High-Efficiency Energy: Zoom Solar Green Energy Technology’s Cadmium Telluride Power Generation Glass: An Appreciation of Excellent Application Case Studies
I. A Rising Star in High-Efficiency Energy: Cadmium Telluride Power Generation Glass
Promoting green and low-carbon economic and social development is a key component of achieving high-quality development and fundamental to addressing my country's resource, environmental, and ecological challenges. As a major energy consumer and CO2 emitter, promoting green buildings is a key approach to energy conservation and emission reduction. Utilizing energy-saving and environmentally friendly technologies and materials to support the realization of low-carbon and green buildings is a crucial path to sustainable development in the construction industry.
Cadmium Telluride power generation glass, a "one-material, multi-functional" energy-saving building material, is constructed by depositing a set of advanced photovoltaic materials between two sheets of ordinary glass, transforming the glass from an insulator into a conductor and enabling power generation. This product boasts high power generation, high efficiency, excellent performance in complex environmental conditions, low energy consumption, and zero pollution. It is also safe, environmentally friendly, and recyclable at the end of its lifecycle, making it a rising star in the field of building-integrated photovoltaics (BIPV).
Zoom Solar Green Energy Technology is a new energy high-tech enterprise focusing on the research, development, production and manufacturing of thin-film solar cells. The conversion efficiency of its independently developed cadmium telluride power generation glass products has reached the domestic leading level. Compared with other similar products, Zoom Solar Green Energy Technology's cadmium telluride power generation glass has the following three unique advantages:
(1) New inverted large-scale cadmium telluride active layer vapor deposition equipment: The in-line solution improves production efficiency by 20% compared with the traditional structure, reduces the dead zone area from 10% to 4%~6%, and increases product efficiency to 17%.
(2) High-precision energy feedback laser modular equipment and technology: greatly improves the quality of the photovoltaic active layer in the volcanic area, further reduces the dead zone area, and increases the module yield by more than 5%.
(3) Hot-pressed non-coated polymer thin layer anti-reflection technology: The anti-reflection cost is 30% of the cost of traditional anti-reflection film, can increase the visible light transmittance by 2.6%, and is suitable for large-area cadmium telluride thin film photovoltaic products, with an absolute efficiency increase of 0.4%~1%.
This allows Zoom Solar Green Energy Technology's CdTe solar-generating glass to truly replace traditional building materials in architectural applications, achieving energy conservation and emission reduction. Below are two classic project examples of Zoom Solar Green Energy Technology's CdTe solar-generating glass. Take a look!
1. Harbin Fiberglass Research Institute Distributed Photovoltaic Power Station
Located in the Science and Technology Industrial Park, Science and Technology Innovation City, Songbei District, Harbin, this project primarily involves rooftops or buildings, including factories, warehouses, power stations, and comprehensive buildings. Through surveying, researching, and designing the existing factory rooftops, the project maximized the solar energy resources on the existing building's rooftops, facades, and surrounding areas, resulting in an effective installed area of approximately 23,145.6 square meters. This project utilizes large-area cadmium telluride thin-film photovoltaic modules. Upon completion, the power station will have a capacity of 3.01375 MWp and generate 3.5988 million kWh of electricity annually. This will effectively alleviate the electricity demand pressure at the Harbin Institute of Technology's production facility and improve the power system's energy structure. It will also save approximately 1,180.39 tons of standard carbon dioxide and reduce carbon dioxide emissions by approximately 3,587.98 tons annually, helping the company achieve cost reduction and efficiency improvements, and achieve its dual carbon goals.
