The solar battery of the highest conversion in the world efficiency 18.6% in Mitsubishi Electric Corporation is developed.

Solar battery that boasts of the highest photoelectric nature conversion efficiency 18.6% in the world developed this time

The solar battery is a battery with the mechanism that the light energy that pours down from the sun is changed into the electrical energy. It comes to obtain a lot of electrical energy by an area that the higher the conversion efficiency is, is the more same, and efficiency can also reduce the produce cost of the acquisition electricity well. 16-18% is being assumed the efficiency of a solar battery module on the market to be about 10% as for the conversion efficiency at the experiment and the developmental level now.

As for the solar battery, because it is possible to produce, the resource (In this case, "Sun light. ") always reproduced without using the resource that dries up is called "Renewable energy" in the fund. Attention has gathered in the solar battery that goes in state-of-the-art of the inside and this renewable energy from which the exhaustion of fossil fuels and the sudden rise are called out. However, to obtain the same electricity because the silicon that becomes a raw material because of the rapid increase of demand is insufficient even by little silicon, making of the silicon wafer and thin meat the improvement of the conversion efficiency are requested from the solar battery.

It succeeded in the solar battery cell that Mitsubishi Electric Corporation developed this time in giving devices such as "The first low reflection texture formation technology development in the world", "Optimization in the joint in the semiconductor", and "The line of the electrode was thinned as much as possible and the power generation area was expanded", and doing and flipping Mr. of this 18.6%. It is scheduled that Mitsubishi Electric Corporation introduces the silicon solar battery cell that developed this time into its own solar battery module after 2010 one by one, and the favor is enjoyed.

It is necessary to consider the problem of "Running cost within a certain period" that comes from putting of holding concurrently with longevity together though the photoelectron for each area nature conversion efficiency of course in the solar battery. The running cost is free same. (The fuel such as oil is useless because the sun light. Only the maintenance cost and the land fee)As for cost into the acquisition energy, if the longevity of and each module is short, and the unit price is high, power generation and any changes in the fossil fuel are lost. If cost becomes expensive even if it is earth friendly, the spread to general is difficult.

It will be requested to be going to devote one's energies to the reduction of the running cost after it thinks by extending the longevity of the solar battery to say nothing of the improvement of the photoelectric nature conversion efficiency in the sales module including the module exchange in the future.
