Innovation of solar battery efficiency is as high as 40.8%

September 1, 2008

Two years ago, american Boeing - the scientist of spectral lab improved the efficiency of the solar battery 40.7% , this kind of cell panel used different semiconductor data, the face of have a common boundary of all sorts of material formed special layer. Such structure can make cell panel ” includes the spectral range of ” is bigger. Compare with photograph of common solar battery can ” captures the more in ” sunshine to plant the photon of wavelengh. Came from American energy department a few days ago but lab of second birth the sources of energy (NREL) the scientist raised this one word 0.1% , achieved 40.8% .

This one word reachs below the imitate environment that is equivalent to quantity of sunshine of 326 typical and sunny weather in intensity, although be the same as the record photograph before to compare,rose only 0.1% , but used disparate structure according to calling this kind of new solar energy face plate, use gallium indium phosphide and gallium indium arsenic to change content material to be spectral cent the share with 3 equal intensity, solar battery board 3 semiconductor knots undertake centralized absorption to each part. According to saying new solar energy face plate is very frivolous, on additional explicit cost than before also reduce somewhat. NREL hopes this kind of solar battery can apply very quickly in orbiter and power station of terrestrial solar energy to come.
