Currently, global energy supply, especially electricity, faces numerous severe challenges. With sustained economic growth and a growing population, energy demand is skyrocketing. Due to the limited and non-renewable reserves of traditional fossil fuels, overexploitation and overuse not only threaten resource depletion but also cause serious environmental problems, such as air pollution, ecological damage, and climate change caused by greenhouse gas emissions.

Against this backdrop, the need to develop green and renewable energy sources such as solar, wind, and hydropower has become increasingly prominent. As a clean, renewable energy source, solar energy is widely distributed and unrestricted by geographical location. Its utilization is clean and pollution-free, without generating greenhouse gases or other harmful emissions. It can help alleviate environmental pressures, mitigate climate change, and promote the optimization and upgrading of humanity's energy structure.

In recent years, the solar photovoltaic industry, both domestically and internationally, has demonstrated remarkable rapid development. Countries have increased their investment and support for solar photovoltaics, and continuous technological innovation and breakthroughs have led to a steady increase in photovoltaic conversion efficiency and a continuous decrease in costs. In China, governments at all levels attach great importance to the development of the solar photovoltaic industry and have introduced a series of supportive policies, including tax exemptions, preferential subsidies, and land use benefits. These policies have fostered a favorable development environment for photovoltaic companies, enabling the formation of a complete and robust domestic photovoltaic industry chain, spanning technology research and development, raw material production, module manufacturing, and ultimately system integration and application.

Currently, solar cell research focuses on high conversion efficiency, low cost, and high stability. As a representative of new productivity in the new energy sector, cadmium telluride thin-film solar cells belong to the latest generation of photovoltaic technology. They utilize a p-n heterojunction structure, consisting of a p-doped cadmium telluride layer and an n-doped cadmium sulfide (CdS) layer. The photovoltaic device is primarily constructed by depositing multiple layers of cadmium telluride thin films on glass or flexible substrates. Compared to first-generation crystalline silicon photovoltaics, cadmium telluride photovoltaics offer numerous advantages, including superior low-light performance, large product area, low temperature coefficient, minimal hot spot effect, high safety, low long-term degradation, minimal carbon footprint, and flexible customization.

Specifically, the advantages of cadmium telluride thin-film solar cells and modules are as follows:

1. Energy yield advantage

(1) The annual attenuation rate of cadmium telluride photovoltaic modules is 0.5%, which means that after 30 years, the module will still have more than 85% of its power generation capacity;

(2) It has excellent temperature coefficient and spectral effect, and can provide 4% more energy per year under hot climate and high humidity conditions;

(3) It has good low-light effect and can generate electricity in low-light environments such as early morning, evening, cloudy and rainy days, and is not very sensitive to power loss;

(4) Small hot spot effect: cadmium telluride thin-film modules are designed with long strip cells, which reduces the hot spot effect, improves product life and safety while increasing power generation capacity.

2. Environmental advantages

(1) Upgrading mining waste tailings to create sustainable and efficient photovoltaic semiconductors. The main raw materials of cadmium telluride photovoltaic modules are tellurium and cadmium. Tellurium is generally found in copper and lead ores in nature, such as copper-lead ore, chalcopyrite and bismuthite. Cadmium is found in zinc ore, sapphire, silver ore and waste materials from zinc selenate batteries. 

(2) The carbon footprint of cadmium telluride thin-film photovoltaic modules is very low. During its life cycle, its carbon footprint is 2.5 times lower than that of crystalline silicon modules and its water footprint is 3 times lower. 

(3) More than 90% of the glass and more than 95% of the semiconductor materials in cadmium telluride thin-film photovoltaic modules can be reused, which can improve material utilization and reduce environmental pollution. 

(4) The surface of cadmium telluride solar modules is float glass, which is smooth and flat, not easy to accumulate dust, easier to clean, and faster and more convenient to operate and maintain. 

(5) According to statistical research by relevant US units, the cadmium pollution index is the lowest during the entire power generation cycle of cadmium telluride solar modules, with a pollution index of only 0.3, which is the same as the pollution index of natural gas. Under the 14th Five-Year Plan and the 2035 Vision, promoting green and low-carbon economic and social development is a key component of achieving high-quality development. The government has intensively introduced a series of support policies to encourage the further integration of "photovoltaic plus" with architecture, transportation, industry, and other sectors.
