High Efficiency Hybrid Solar Cell
This invention relates to a high efficiency hybrid solar cell comprised of a dichroic mirror, a first cell stack comprising two cells, the first cell being a GaInP cell and the second cell being a GaAs cell and a second cell stack comprising three cells, the first cell being a Si cell, the second cell being a GaInAsP cell and the third cell being a GaInAs cell. The dichroic mirror provides a separation of the solar light into two spectral components, one component of light with photons of energy greater than or equal to Eg that impinges upon the first cell stack and one component of light with photons of energy < Eg that impinges upon the second cell stack.
