Sharp and the Japan Aerospace Exploration Agency (JAXA) have jointly developed thin and light photovoltaic cells for use in man-made satellites and spacecraft.

Weight is only about 1/7 of the traditional photovoltaic solar powered portable generator cells, while power generation efficiency is higher. The use of such batteries will help to achieve satellite weight, the use of small, cheap rocket can launch. Will be the first in December to verify its power generation capacity and durability in space, and actively promote Japan's domestic and foreign satellite manufacturers to use the battery. The new battery can be used for the surface of the satellite, weighing only 1/7 of the traditional battery.
Photovoltaic cells
Photovoltaic solar power generator cells account for about 10% of satellite weight. The newly developed battery thickness of only 0.3 mm, the use of thin film batteries in the resin film in the form of fixed. Allegedly, the battery power generation efficiency is about 32%, reaching the highest level of global satellite photovoltaic cells. Since the battery is very thin and flexible, it can be attached to a curved surface of a satellite body or the like where it is difficult to install a battery. By enlarging the battery area and increasing the power generation capacity, the satellite can be equipped with an observer to improve the satellite performance.

JAXA will be in the space station for the delivery of unmanned aerial vehicle spacecraft set up this new battery, is expected to launch in December. In addition to testing the new battery can withstand the rocket launch when the strong vibration, but also will be exposed to space for 3 months or so, verify whether the battery in accordance with the expected power generation.

According to the US Satellite Industry Association data, satellite-related industries in 2015 the size of the market reached 208 billion US dollars, compared with 2010 increased by 20%. In the future, with the increase in the number of small satellite launch, the demand for space photovoltaic cells will also be expanded.
