1, the power generation principle is different.
Thin-film power generation relies on thin-film solar cell chips with light, thin and flexible characteristics, embedded in various carriers like Intel Inside, to provide clean power. Photovoltaic power generation is a technology that directly converts light energy into electric energy by using photovoltaic effect of semiconductor interface.
2. Different uses
Thin-film power generation is mainly used in mobile phones, iPad, backpacks, tents, clothes, special equipment, or solar cars, which can be charged while driving in the sun and get rid of dependence on charging piles. Photovoltaic power generation is used in static power generation devices such as solar water heaters.
3, the use of different technologies
Thin film power generation uses solar chips to generate electricity, and photovoltaic power generation uses photovoltaic effect of semiconductor interface to generate electricity.

Advantages and disadvantages of photovoltaic power generation
superiority
No matter from the world or from China, conventional energy is very limited. China's primary energy reserves are far below the world average, accounting for only about 10% of the world's total reserves.
Solar energy is an inexhaustible renewable energy source for human beings, which has the advantages of complete cleanliness, absolute safety, relative popularity, long service life, maintenance-free, abundant resources and potential economy, and occupies an important position in the long-term energy strategy.
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation are mainly reflected in:
(1) there is no danger of failure;
(2) Safe and reliable, without noise and pollution discharge, absolutely clean (pollution-free);
(3) Not limited by the geographical distribution of resources, the advantages of building roofs can be utilized; For example, areas without electricity and areas with complex terrain;
(4) local power generation and power supply can be realized without consuming fuel and erecting transmission lines;
⑤ High energy quality;
⑥ Users are easy to accept emotionally;
⑦ The construction period is short, and the time required for obtaining energy is short.
disadvantaged
However, the production of solar panels is characterized by high pollution and high energy consumption. Under the existing conditions, it is ok to produce panels for domestic use, but a large number of exports are equivalent to polluting China and benefiting the world.
According to statistics, to produce a 1m× 1.5m solar panel, more than 40 kilograms of coal must be burned, but even the most inefficient thermal power plant in China can generate 130 kwh of electricity with these coals (generally one 1mx 1.6m).
(1) irradiation has a small energy distribution density, which means it will occupy a huge area;
(2) The energy obtained is related to meteorological conditions such as four seasons, day and night, sunny and rainy.
③ At present, compared with thermal power generation, the opportunity cost of power generation is higher.
④ Photovoltaic panels are not environmentally friendly in the manufacturing process.
