With the global emphasis on energy security and environmental protection, clean energy as a sustainable form of energy has attracted much attention. Among them, photovoltaic technology as one of the most representative clean energy, rapid development in the world. This paper will discuss the development history, current situation and future prospect of photovoltaic technology, as well as the application prospect of photovoltaic technology.
I. Development and application of photovoltaic technology
(I) Development history of photovoltaic technology
Photovoltaic technology originated in the 1950s and was originally used in the space industry. In the 1970s, with the advent of the energy crisis, solar power gained prominence as a clean source of energy. Photovoltaic technology begins to expand to the civil market and becomes a choice to solve the energy problem. Photovoltaic technology has made significant advances in materials, structures and manufacturing processes, significantly reducing costs while increasing the efficiency of photovoltaic conversion. At present, photovoltaic technology has become one of the most representative clean energy, has been widely used around the world.
(II) Current situation of photovoltaic technology
At present, the global photovoltaic power generation has formed a large-scale industrial chain, photovoltaic cell production has entered the mature stage. In 2019, global installed PV capacity exceeded 600GW, with China accounting for nearly half of the market share. At the same time, the cost of photovoltaic power is falling and it is already competitive with traditional forms of energy. As the technology continues to improve and economies of scale gradually play, the cost of photovoltaic power generation will further fall, the scope of application will also expand.
(III) Application prospect of photovoltaic technology
With the increasing global demand for clean energy, photovoltaic technology has a broad application prospect in the field of energy. Photovoltaic technology can be applied to the roof, curtain wall, balcony and other parts of the building to achieve energy conservation and environmental protection. At the same time, photovoltaic technology can also be applied in agriculture, industry, transportation and other fields to provide clean energy solutions for various industries. In the future, with the continuous development and innovation of photovoltaic technology, its application will be further expanded and become an important force to promote the global clean energy transition.
The development course, present situation and application prospect of photovoltaic technology show a sustainable development trend. With the continuous improvement of technology and the continuous reduction of cost, the application prospect of photovoltaic technology will be more broad. As a clean and renewable form of energy, photovoltaic technology will play an increasingly important role in the world. We have reason to believe that in the future, photovoltaic technology will become an important force driving the global clean energy transition.
II. Environmental and social impacts of photovoltaic technology
(I) Environmental impact of photovoltaic technology
Photovoltaic technology has many advantages as a clean, renewable form of energy, but the manufacturing, transportation, installation and maintenance of photovoltaic cells also have environmental impacts. For example, the manufacturing of photovoltaic cells requires a lot of energy and materials, as well as waste and pollutants. In addition, the production and transportation of photovoltaic cells also bring certain carbon emissions and other environmental impacts. Therefore, when promoting and applying photovoltaic technology, it is necessary to consider its environmental impact and take corresponding measures to reduce environmental pollution and carbon emissions.
(II) The social impact of photovoltaic technology
In addition to the environmental impact, the application of photovoltaic technology also has a social impact. The application of photovoltaic technology can bring jobs and economic development, while also promoting local energy self-sufficiency. In addition, photovoltaic technology can also improve energy security, reduce energy dependence, and bring greater welfare to society. However, in the application of photovoltaic technology, issues such as social justice and equity should also be considered to avoid causing social problems such as the gap between the rich and the poor.
The application of photovoltaic technology is an important part of the clean energy transition. When promoting and applying photovoltaic technology, it is necessary to consider its environmental and social impact, and take corresponding measures to reduce the negative impact. With the continuous progress of technology and the continuous reduction of cost, the application prospect of photovoltaic technology will be more broad. We have reason to believe that in the future, photovoltaic technology will become an important force driving the global clean energy transition.
