Abstract
This invention relates to an encapsulation structure comprising a luminescent wavelength conversion material for at least one solar cell or photovoltaic device which acts to enhance the solar harvesting efficiency of the solar cell device. The luminescent wavelength conversion material comprises at least one chromophore and an optically transparent polymer matrix. Application of the encapsulation structure, as disclosed herein, to solar harvesting devices, including solar cells, solar panels, and photovoltaic devices, improves the solar harvesting efficiency of the device by widening the spectrum of incoming sunlight that can be effectively converted into electricity by the device.
