Thin film batteries can be classified into microcrystalline thin film batteries, compound thin film batteries, and organic thin film batteries according to material classification. At present, in the thin film battery, the mainstream is still a silicon thin film battery and a cadmium telluride battery.

Thin film batteries have received widespread attention mainly because of its many advantages. First of all, its temperature is very good. For example, cadmium telluride batteries have a very good temperature coefficient and improved temperature rise performance. In general, as the temperature increases, the conversion rate of the crystalline silicon cell decreases. Secondly, the low light is good. Thin film batteries can also generate electricity when the morning and afternoon light is weak. Then there is its strong environmental adaptability. Thin film batteries are relatively cost effective, so their cost is also low.

Since the thin film battery can complete a production in the whole workshop, its process integration is very high, which also leads to its economic benefits are not ideal, and it is more difficult to upgrade its technology. At present, thin film batteries have been widely used in real life, such as the megawatt power station of the 、, and the 3 kW power station on the roof of our national photovoltaic center.

There are two types of thin film battery testing, one is material testing and the other is electronic property testing. Material testing, generally in the production process of thin film batteries, needs to be tested for its composition. The detection of battery performance is the most critical. At this time, static or steady sunlight is generally used. However, its photovoltaic response should also have environmental testing. The best method in environmental testing is outdoor testing, but outdoor testing is affected by weather, season, latitude and temperature, which means that with these changes, its power generation efficiency changes.

The National Photovoltaic Product Quality Supervision and Inspection Center is approved by the General Administration of Quality Supervision, Inspection and Quarantine, and the state-level supervision and inspection institution for franchise photovoltaic products and their materials quality, which has the impartial status of third parties and is the highest performance of China's current PV series testing. Testing laboratory. At present, the area of ​​the laboratory is 9,400 square meters, and the fixed assets reach 190 million yuan, of which the equipment will reach 150 million yuan. We have a large number of advanced testing equipment and have established a material analysis laboratory for material characterization.
