Márpedig akárhogy is nézem, mindkét csúcscella spektrumbontást csinál.

A német:

"For these highly efficient structures, it is decisive that the solar spectrum is divided into three equally large spectral regions by a suitable choice of light absorbing materials. In this way all of the three subcells generate the same amount of current. This is an important argument in favor of a serial connected solar cell, where the device current is limited ultimately by the smallest current generated by one of the subcells. By choosing the metamorphic Ga_0.35In_0.65P/ Ga_0.83In_0.17As/Ge material combination, a solar cell structure could be chosen for the first time that is completely current matched under the terrestrial solar spectrum. "

Az amerikai:

"The highly efficient VHESC solar cell uses a novel lateral optical concentrating system that splits solar light into three different energy bins of high, medium and low, and directs them onto cells of various light sensitive materials to cover the solar spectrum. "
