Today, the solar industry is blossoming, with solar panels gaining momentum. But the history of the development of solar energy is little known, today let us learn about solar energy and the history of the development of solar panels.
1. The history of the development of solar energy.
1.1 Beginning:
1839: In the history of human development, the first invention related to solar energy appeared in 1839, a young French physicist Alexandre Edmond Becquerel because of the fascination with the photoelectricity of the knowledge of physics, and so perennial in the laboratory for related experiments and inventions. Finally, in 1839, when he was 19 years old, he discovered the photovoltaic effect and created the first photovoltaic cell based on it.
1.2 Exploration Period:
1839~1882: Under the influence of this young physicist, a large number of scientists devoted themselves to the cause of solar energy.
1961, the patent of solar motor was applied by Auguste.
1873, Willoughby discovered the photovoltaic effect of selenium;
1882, the first solar power generator came out in history.
1.3 Period of Understanding:
In this period, many theories of interconversion with photovoltaics appeared one after another, providing a theoretical basis for the development of solar cells. In this period, there appeared two figures who played an important role in the theory of photovoltaics. 1887, Hertz discovered that light energy could make electrons emanate from the inside of a metal and form an electric current in a closed circuit. The second figure was the famous American physicist Albert Einstein, who introduced the concept of light as a packet carrying electromagnetic force further promoting the development of photovoltaic theory.
1.4 Development Period:
1941~1972: At this time, the theory of solar photovoltaic power generation had already taken shape, and monocrystalline silicon solar panel appeared for the first time, laying the foundation of modern solar cells. In this period, as the global resource reserves had begun to be depleted after World War II, many stronger countries began to vigorously develop the solar energy industry to cut down on the impact of World War II.
1947, passive solar houses began to develop.
1951, germanium was put into the manufacture of solar cells.
1955, the first solar-powered telephone appeared, and
1958, Pioneer, I satellite used a miniature panel to power the radio. A miniature battery panel to power the radio. Since then, solar technology has been gradually applied to the aerospace industry.
In 1973, the world’s first photovoltaic power station, Solar One, was built.
In 1999, Germany spent half a billion dollars on a 100,000 solar roof program.
Since 2008, due to Germany, Spain and other countries to vigorously subsidize, the cost of photovoltaic modules fell dramatically, solar panels began to be common.
2015, Tesla launched a new solar energy products Powerwall, the price is extremely low, which also makes the solar energy products to be further common use.
2024, some countries to implement tax credits can save the cost of installing 30% of the cost of solar panels, the development of solar panels is emerging towards prosperity.
2. Invention of solar panels
The invention of solar panels is a combination of the achievements of many physicists, coupled with the joint efforts of generations of scientists, before the invention. Therefore, there are many different opinions about the inventor of solar panels. Some say it was Alexandre who discovered the photovoltaic effect, while others say it was Charles Fritts who invented solar cells made from selenium wafers, but since the solar panels we currently use are generally made from monocrystalline silicon, I believe that none of the above statements are accurate. The real invention of solar panels should be Daryl Chapin, Calvin Fuller and Gerald Pearson, who first invented the silicon photovoltaic cell is the basis of the current solar panels.
3. The development prospect of solar panels
Today, as the greenhouse effect is gradually increasing, reducing the use of fossil fuels has become a mainstream trend, therefore, seeking a new energy source to replace fossil fuels has become imminent. Solar energy, as a renewable green resource, has begun to be emphasized by many countries, so the development prospects of solar panels are bright.
