The photoelectric conversion efficiency of thin-film solar cells is not as high as that of traditional crystalline silicon cells. Improving the conversion efficiency of thin-film solar cells is the main direction of continuous research in the solar technology community. So far, the photoelectric conversion efficiency of cadmium telluride thin-film solar cells in the laboratory has reached 21.5%. First Solar, the world's largest manufacturer of cadmium telluride solar modules, plans to achieve 16% efficiency in related modules by 2015. Currently, the efficiency of thin-film solar cells of copper indium gallium selenide exceeds 21%, and the efficiency of related components will also reach 15%.
Thin film solar cells currently on the market include:s cadmium telluride thin film solar cells, copper indium gallium selenide thin film solar cells and amorphous silicon thin film solar cells.
Current situation of Hanergy Group
Compared with traditional crystalline silicon photovoltaics, thin film solar is light, thin and flexible. A thin film solar chip can be mounted on various. carriers. As a result, various products can be produced. Taking Hanergy as an example, the currently launched products include Han paper, Han bags, Han umbrellas, Han tiles, Han roads, etc., with various application scenarios such as "living, using and traveling".
Let's take Hanbao as an example. It can replace the function of a power bank and obtain "power when there is light". It adopts a split design and is equipped with the first flexible thin film co-evaporated to the world. Solar technology. It can also work normally under occlusion, low light and low temperature.
What is the difference between Hanergy thin film power generation and other photovoltaic power generation?
Nine main companies of China Hanergy Group have been bankrupted and liquidated.
The Beijing No. 1 Intermediate Court issued a statement inviting social intermediaries to compete online to select managers for the bankruptcy liquidation of nine core companies of Hanergy Group.
These 9 companies include: Beijing Zhixun Technology Co., Ltd., Bingcheng Energy Holding Group Co., Ltd., Jinjiang Hydropower Group Co., Ltd., Juntai Innovation (Beijing) Technology Co., Ltd . ., and Hanergy New Materials Technology Co., Ltd., Beijing Zhicheng Technology Co., Ltd., Beijing Hanergy Thin Film Solar Power Engineering Co., Ltd., Beijing Jingcheng Platinum Solar Equipment Co., Ltd. and Beijing Hanergy Thin Film Power Generation Investment Co., Ltd.
This storm of Hanergy companies filed for liquidation began in July 2020. After the Beijing No. 1 Intermediate Court first announced a bankruptcy review of Hanergy Mobile Energy Holding Group Co ., Ltd., Hanergy Mobile Energy Holdings Group Co., Ltd. Creditors of a series of Neng's companies followed suit and filed for liquidation.
Hanergy Honors
On August 27, 2019, in the 2019 “Top 500 Asian Brands” by WorldBrandLab List, Hanergy won the title of “ Top 500 Asian Brands" for the fourth time. The brand ranked 72nd, up 7 from 2018, becoming the only company in Asia to be selected among solar energy companies.
< p>In July 2019, Hanergy Group ranked 456th in the latest 500 me listFortune's Best Chinese Companies. In the two sub-lists of “Top 40 Return on Equity (ROE)” and “Top 40 Profit Margin” published at the same time, Hanergy was both shortlisted.Among them, among the 40 companies with the highest return on equity (ROE), Hanergy Group ranks 7th with a return on equity of 37.99%, becoming the only company among the top 40. energy companies.

The two have the following differences:< /p>
1, different principles of power generation
Thin-film power generation relies on thin-film solar cell chips that are light, thin and flexible, integrated into various media such as Intel chips (Intel Inside), to provide clean energy. Photovoltaic energy production is the uUse of technology that directly converts light energy into electrical energy through the photovoltaic effect at the semiconductor interface
2. Different uses
Thin. -Film power generation is mainly used in mobile phones, iPads, backpacks, tents and clothing, special equipment or solar cars, can be charged while driving in the sun, eliminating the dependence on charging piles. for stationary power generation devices, such as solar water heaters
3. Different application technologies
p>
Thin film power generation uses solar chips to produce electricity and photovoltaic power. generation uses the photovoltaic effect of the semiconductor interface to produce electricity

Production advantages and disadvantages ofphotovoltaic energy
Advantages
Whether from the world's perspective or from China's perspective, conventional energy is very limited. China's primary energy reserves are far below the global average, accounting for only about 10% of the world's total reserves.
Solar energy is an inexhaustible renewable energy source for humanity and is entirely clean, safe and relative. reliable and maintenance-free long service life, resource adequacy and potential saving, etc., play an important role in long-term energy strategy.
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
①No risk of depletion
②Safe and reliable, no noise, in addition to the absence of polluting emissions, it is absolutely clean (no pollution);
③It is not limited by geographic distributionraphics resources and can take advantage of building roofs, for example, areas without; electricity and areas with complex terrain;
④Can generate electricity and provide electricity on site without consuming fuel or erecting transmission lines;
⑤High power quality;
⑥Easy to use users need to accept emotionally;
⑦ The construction period is short and the time spent on obtaining energy is short.
Disadvantages
However, the production of solar panels is characterized by high pollution and high energy consumption. Under the existing conditions, domestic production requires.The used panels are acceptable, but exporting them in large quantities will pollute China and benefit the whole world.
According to statistics, more than 40 kilograms of coal need to be burned to produce a 1m x 1.5m solar panel, but even if Chinahas the least An efficient thermal power plant can also use these coals to produce 130 kWh of electricity (typically a 1m x 1.6m solar panel generates over 250 kWh per year) - this is enough to power a light 2.2 watts. Light emitting diode (LED) bulb according to work 12 hours a day and glows for 30 years.
① The energy distribution density of irradiation is small, that is, it occupies a huge area
② The energy obtained is related in the four seasons, day and night, cloudy; and sunny and other weather conditions.
③ At present, compared to thermal power generation, the cost of generators is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
