Panasonic developed a "perovskite type" of solar cells. Manufacturing only through the printing method of organic materials can be coated, the cost is low. The solar power battery is thin and soft, can be attached to the stadium's circular roof or curved walls, but also for wearable equipment, even if attached to the glass window will not affect the light transmission. The solar battery is expected to be used as the monitoring of infrastructure safety outdoor sensor power supply.
Perovskite-type portable battery generator efficiency is too low has been seen as the subject, but in recent years the rapid increase in power generation efficiency, gradually close to the mainstream of the silicon cells. But perovskite batteries do not have durability, a few hours or a few days after the performance will be reduced, which has become a practical barrier, had only remained in the university research and development stage.
Panasonic and the Swiss Federal Institute of Technology, Lausanne, jointly improved by the light-generating power generation layer. Studies have found that by adding metal rubidium to conventional materials, it is possible to produce pure crystals with few defects and remarkably improve the durability of the battery. The manufacturing cost is said to be the same as before.
Conventionally, as a method of manufacturing an organic thin-film solar cell, a "vacuum deposition method" has been generally used. A disadvantage of the vacuum deposition method is that a large-scale manufacturing apparatus is required, so that the production cost is high and a large area is difficult to be realized. On the other hand, Mitsubishi Chemical's products can be easily manufactured by printing on a film substrate or the like come out. Therefore, the manufacturing apparatus is relatively small and can be mass-produced. But also easy to achieve a larger area.
First of all, with reference to the printing process parameters, which is only on the printing speed, material back speed, wire mesh gap requirements, other parameters are not involved. Then that is, according to theory, we can modify other parameters to adjust the printing process working hours. After analysis, we have to shorten the printing stroke, reducing the screen in the printing of the up and down travel, increasing the Z-axis direction of the screen speed, solar battery generator increase the transmission parts of the motor step distance, increased Compressed air pressure of cylinder.
Making it possible to use a printing technique, which is an organic semiconductor material developed by Mitsubishi Chemical. Organic thin-film solar cells require the use of two organic semiconductor materials. One is a "p-type organic semiconductor" which emits electrons upon exposure to light. And the other is an "n-type organic semiconductor" which can take electrons and transfer them to the electrodes. portable battery generator can also be printed as "printed" production. Yesterday, the reporter from the Wuhan Polytechnic Materials Composite State Key Laboratory of New Technology was informed that the laboratory is currently working with a well-known automotive glass manufacturers to negotiate its "printing" research and development of translucent photovoltaic glass is expected to promote the development of new energy vehicles.
The new solar batteries and ordinary colored translucent glass is no different, but placed under the light of the table lamp, the battery can quickly produce power to drive the fan rotation. Unlike ordinary solar cells, the new battery is produced by the "printing". Researchers only need to tune a special "ink" down to a variety of substrates, solar cells can print the same as newspapers, a block produced.
4 mm square size of the perovskite-type trial solar battery power generation efficiency of 21.6%. Although the mainstream than the current record of silicon solar cells 4.7 percentage points lower, but in the perovskite-type solar cells reached the top level.
The perovskite type solar cell was subjected to a durability test in accordance with a standard method. In the 85 ° C temperature and humidity 85% of the harsh environment of continuous solar power generation, after 3 weeks to confirm the performance did not decline, is expected to be in normal circumstances can be used 2-3 years.
Matsushita will continue in the future to maintain high-performance battery on solar power generator while promoting large-scale research. The durability of the battery will be further improved, in order to achieve the manufacture of new long-life solar power batteries.
