01 How does a building generate electricity?
Building power generation is generally achieved through thin-film or crystalline silicon photovoltaic laminated glass or photovoltaic insulating glass composed of the aforementioned photovoltaic laminated glass, forming a solar photovoltaic power generation array as the outer surface of the building envelope to provide green electricity. This type of application is also known as Building Integrated Photovoltaics (BIPV). BIPV not only achieves perfect integration with buildings, but also generates electricity that can be used by buildings. It is an interdisciplinary field between the construction and photovoltaic industries, which can promote the deep integration of the construction and photovoltaic industries.
02 Cadmium telluride power glass has become a new favorite in the BIPV market
Cadmium telluride power glass is an energy based building material that is versatile, green, energy-saving, and innovative. It has strong power generation capacity and low temperature coefficient, making it very suitable for application in distributed, modular, and integrated green buildings. Cadmium telluride power glass can be finely customized in terms of color, texture, and size, ensuring perfect integration with the architectural appearance style. To endow buildings with unique aesthetic charm and achieve a dual enhancement of functionality and aesthetics.
It is reported that a piece of cadmium telluride power glass, 1.6 meters long and 1.2 meters wide, can generate electricity at around 260-270 degrees per year. It is insensitive to the angle of light incidence and temperature, and under the same scenario and installed capacity, its power generation is more than 10% better than that of crystalline silicon cells. Even if the light is weak, it can generate electricity through photoelectric conversion, providing environmentally friendly, low-carbon, energy-saving and efficient power guarantee for daily life, and helping traditional buildings transform into "near zero energy consumption" and even "production capacity buildings".
To achieve this transformation, we need to start from the following aspects:
1. Technical selection and evaluation
Choose suitable cadmium telluride power glass products: Based on the characteristics of the building and electricity demand, select cadmium telluride power glass with appropriate transparency, color, and size.
Technical parameter evaluation: Evaluate the key parameters such as power generation efficiency, temperature coefficient, and weak light power generation performance of cadmium telluride power glass to ensure that it can meet the energy needs of buildings.
2. Design and integration
Develop a comprehensive renovation plan: Based on the characteristics of the building structure, design the installation location and scale of the power generation glass, such as facade walls, roofs, windows, etc.Ensure structural safety and aesthetics: Ensure that the installation of cadmium telluride power glass does not affect the structural stability of the building, while coordinating with building aesthetics.
3. Construction and installation
Choose a professional construction team: The construction team needs to have experience in installing cadmium telluride power glass to ensure the safety and correct installation of power glass.
Consider grid access and energy management: During the installation process, it is necessary to consider the connection method with the internal power grid of the building, as well as the management and utilization strategy of power generation.
4. Monitoring and maintenance
Establish an energy monitoring system: Real time monitoring of the operation status and power generation of cadmium telluride power glass, timely detection and resolution of problems.
Regular cleaning and maintenance: Keep the surface of cadmium telluride power glass clean to maintain optimal power generation efficiency; Regularly check the electrical connections and structural stability.
5. Performance optimization and upgrade
Utilizing advanced technology to improve performance: Through technological upgrades such as optimizing transparent conductive layers and monitoring hot spots, the performance of cadmium telluride power glass can be further improved.
Adaptation to climate change: Adjust the angle and cleaning frequency of cadmium telluride power glass according to seasonal changes and climate conditions to maintain optimal power generation efficiency.
Overall, transforming an existing building into a production capacity building is a systematic project that requires comprehensive consideration of multiple aspects. Promote the development of the construction industry towards green, low-carbon, and sustainable direction through reasonable planning and implementation.
