1. What are the innovations that need to be changed for solar energy development

(1) solar panel efficiency development

Now the biggest drawback of solar panels is that the efficiency is too low, the efficiency of solar panels in today’s market has never been able to break through 30%, such as JinkoSolar, Trina and other world-renowned brands, the efficiency of the 23% or so, there are still most of the energy can not be utilized in the future to think of the development of photovoltaic industry must break through the efficiency of power generation in recent years the efficiency of the solar panels have been growing, the efficiency of the efficiency of the current generally in more than 25%. The efficiency of solar panels has been increasing in recent years, and now the efficiency is generally above 25%.

(2) Material development of solar panels

Now silicon as the main material for solar panels, although the safety is guaranteed, but the efficiency has never been a big breakthrough, people are gradually trying new materials, such as calcium and titanium solar panels have been out of the laboratory although not mass output but calcium and titanium solar panels can easily reach 25% efficiency, the development prospects are broader, the material is also cheaper if you can that would realize the vision of everyone 1 solar energy, I believe that can break through the 30% barrier. for the materials that still exist in the experiment, such as semiconductor materials, although it is difficult to manufacture this material there are other shortcomings, but at this stage by the semiconductor materials manufactured by the efficiency of solar panels can reach 47%, compared to the current use of solar panels to get a huge breakthrough, and I believe that there will be other high-efficiency materials to be considered, the future of solar panels have a very good prospect for the development of the future.

2. Some important new solar technologies

2.1 Chalcogenide solar technology

Chalcogenide solar cell is a new concept cell. At present, most of the solar cells used are silicon-based solar cells (monocrystalline silicon, polycrystalline silicon, amorphous silicon solar cells), compared to these types of solar cells, theoretically, the photoelectric conversion efficiency of chalcogenide solar cells is much higher. Moreover, chalcogenide solar cells have excellent photovoltaic properties such as high absorption coefficient and high carrier mobility, and its preparation does not require high purity of raw materials, low preparation cost, and simpler process.

2.2 Solar seawater greenhouse

About 71% of the earth is the ocean, but human survival and development of the necessities of fresh water, seawater and can not be directly drinking or watering crops, often need to be desalinated for people to use. However, desalination of seawater consumes huge amounts of energy and exacerbates the greenhouse effect. Moreover, in some arid areas where freshwater resources are scarce, it is difficult for crops to grow normally, which will reduce food production. At this time, the development of solar seawater greenhouse technology can well mitigate these situations. It uses solar energy to generate heat, so that seawater evaporation and condensation, and then through a series of steps can achieve the purpose of desalination of seawater, which can be used for agricultural irrigation. The advantage of solar seawater greenhouse is not affected by steam, electricity, etc., and does not consume coal, oil and other energy substances, no pollution, and the fresh water obtained is also higher purity.

2.3 Floating Solar Technology

This technology makes the solar panels get rid of the traditional installation method, so that the installation of solar panels is no longer limited to land and houses, and effectively utilizes the water resources. This solar panel installation method effectively improves water quality and reduces water evaporation. Moreover, when the solar panel is installed on the water surface, the water body can also reduce the surface temperature of the solar panel and improve its working efficiency. For some fisheries development, solar panels can be installed on the surface of the pond, which can prevent algal blooms in the water body, and also provide shade for fish, and the electricity generated can also be used for household use.

2.4 Transparent solar panels

It is reasonable to say that the solar panel can not be completely transparent, because it needs to absorb photons and convert them into electrons, and if it is completely transparent, it can not absorb light energy. But some scientists have created a transparent solar concentrator to make transparent solar panels a reality. Installing it on a building will not affect the aesthetics of the building and it can also utilize the light energy effectively.

2.5 Portable solar panels

In some areas, weather such as hailstorms often worry some users who have installed solar panels. A little improper protection, the solar panels may be damaged, and the emergence of portable solar panels to eliminate the worries of these users. You can disassemble the solar panels and store them in the event of bad weather such as hailstorms and snowstorms, and then assemble them after the storm has passed, effectively avoiding damage to the solar panels.

2.6 Bifacial solar panel

Traditional solar panels can only utilize light energy on one side, while bifacial solar panels absorb light energy from both sides. This kind of solar panel effectively improves the efficiency of power generation and is suitable for installation in some weak light areas.

2.7 Solar windows

This is a technology that uses photovoltaic glass. Windows are an essential component in every house and this technology converts the light that hits the window into electricity, acting as a window as well as being used to generate electricity. This technology avoids taking up too much space as compared to the installation of traditional solar panels.

2.8 Solar Wearable Technology

Going out on the body of electronic equipment power supply is always a problem, in recent years, electronic watches and portable electronic devices have become a necessity in life, solar wearable technology will be wearable devices equipped with micro-solar batteries on the surface of the sunlight can be converted into solar energy for wearable equipment power supply, whether hand or watch do not have to carry a charger to realize solar energy as energy.

2.9 Solar panels and building integration

In the form of solar power for the future envisioned in a special combination was mentioned, the solar power and building integration, in the wall windows can be traveling power generation capacity, this vision also caused an increase in the flexibility of the solar panels, solar panels can be adapted to a variety of occasions, and no longer for the stenting of the racking, the solar panels are now occupying the roof and stenting perforation results caused by the solar panels can be effectively avoided.

2.10 Artificial Intelligence combined with solar energy systems

For the development trend of solar panels, the combination of artificial intelligence makes the use of solar panel systems more skilled artificial systems is the main direction of future development, combined with artificial intelligence can be more convenient to mobilize the power of solar panels for home use can maximize the deployment of household electricity needs.

2.11 Solar transportation development

From fuel cars to electric cars to confirm the future development in the direction of green and clean, solar energy can be used directly as a source of power, the idea of solar cars is not far away, with the development of solar energy technology, this idea can even support the operation of large-scale transportation, such as airplanes.

Conclusion

The current solar energy technology in most areas have played a great use, reflecting their value, in the development of new solar energy technology on this road, mankind will always go on, to bring a more perfect solar energy technology.
