Recently, researchers in the United States related journal of the American Institute of Electrical and Electronics Engineers (IEEE) in the "Journal of Electron Devices" published a paper titled "Let's household photovoltaic devices become reality". 

It is understood, researchers have proposed a new lower cost of photovoltaic power generation multi-terminal multi-link structure, power generation efficiency can exceed the current 25%. The structure is based on the current commercial silicon solar cells, and thin-film solar cells made of copper oxide and other materials, and these materials are rich in reserves in the ground shell resources. 

The new solar cells, photovoltaic power generation is expected to reduce costs and improve the efficiency of power generation. In the near future, photovoltaic power generation or will truly enter homes. 

Today, through the micro-grid photovoltaic power generation and transmission of electricity in rural areas without electricity is the best way. This is the United States and other developed countries, to replace aging power generation equipment and transmission infrastructure best choice.
