Content overview

Mr. Shi Zhengrong is engaged in the new energy industry, which involves new materials and photovoltaics, that is, the field of technologies, materials and devices that generate electricity through sunlight. Eighteen years ago, this industry grew from scratch, from backwardness to leading the world. Now China's photovoltaic industry has become one of the business cards representing China. As a socially responsible designer, researcher, scientist and practitioner in the field of industry , Need to rethink the new application of photovoltaic green energy in life scenarios.

The so-called photovoltaic is a solar photovoltaic cell. It is a semiconductor device. After absorbing light, it is excited by the energy of light to generate positive and negative electricity. The internal electric field forms a current and voltage, and then electricity can be generated. Energy to drive all electrical devices. People want to go online at a fair price, but the cost of photovoltaic power generation was relatively high in the past. There are several important concepts related to photovoltaic power generation and parity grid access. First of all, as a user who wants to surf the net at a fair price, they must have a factory and install a solar photovoltaic power plant on the roof of the factory, so that photovoltaic power generation can compete with traditional power generation. In the past 20 years, in order to encourage everyone to use green and clean energy photovoltaic power generation, many governments have granted user subsidies, including China.

This industry has only just begun in China in 2005. Before that, China was a blank. In the past more than ten years, China has been far away from the aspects of technology, equipment, manufacturing, cost and quality. It ’s ahead of the whole world, so you can see that the cost of electricity and energy consumption has dropped dramatically. Similarly, after the raw materials are available, they must be made into chips. Silicon technology is also far ahead of the world in terms of technology, equipment, output, and cost. This is what is happening in every industry chain. Conversion efficiency is also constantly improving. The technology roadmap is very clear. The next step is how to develop technology to improve conversion efficiency while reducing manufacturing costs. Moreover, the equipment brand has changed from 100% foreign to 100% now, and now it is exported in large quantities. China has also changed from a so-called photovoltaic manufacturing power to a power application power. In the past five years, our country has actively responded to changes in climate and vigorously developed green energy. China has become a major application country. This transformation has made China a leader in global clean energy and energy transformation, which has produced a huge and profound And positive impact.

The picture above is a business card of the 19th National Congress of last year. China's photovoltaic industry has become China's business card along with wind energy, high-speed rail and aerospace. So when it comes to China's photovoltaic industry, foreigners will give thumbs up. Since the photovoltaic industry is a green and clean energy power generation industry, and can enter thousands of households, unlike thermal power generation, which has to build power plants into factories, photovoltaic power generation can be organically combined with daily life, so the application of this industry will The large-scale ground power station is transferred to the roof and becomes a building material. It is difficult to install photovoltaic directly on the roof of every house, so it must be part of life through organic integration. In recent years, the innovation of new materials and new technologies has also allowed designers to integrate this product into our lives in a more artistic and beautiful way. I believe that clean energy can change the world and make our blue sky bluer.

The structure, mechanical properties, insulation properties, reliability, safety, and service life of more than 25 years of the materials need to be considered in the development of materials and process products. Its weight is only a quarter of the weight of glass products, and it can be customized. Just like a tailor's clothes, various designs of appearance, size and size can be realized, and the cost is controllable. Due to special materials and special processes, its mechanical and electrical functions will not be destroyed when it is bent. With such materials and these functions, it becomes possible to make photovoltaic green energy into daily life.

This material can change color and shape, but the power generation function will not be changed. It can be applied to lightweight roofs, can be made into folding and portable photovoltaic carports, can be designed as mobile energy, and can also be designed as sunflower photovoltaic panels and other commercial applications. It can also be perfectly combined with the building and make full use of the construction area to generate electricity.

Imagine that architects need to imagine, need more colors, and need more shapes. From the perspective of an architect designer, a building is a reaction of the designer ’s ideas, giving architects materials to let them play their full The artistic imagination can inspire more product possibilities.

In the speech, Mr. Shi Zhengrong provided some ideas for everyone from the perspective of engineering and technical personnel, and raised a question for everyone. It is expected that designers can use their imagination to imagine green generators, which may be miniature, small or large generators, and use our higher concepts and more beautiful designs to help green energy enter daily life.
