    • A stacked luminescent solar concentrator includes two separate absorption/emission cells, each having a layer of luminophore-type material, wherein a top layer is a high band gap layer comprised of quantum dots in polymer, wherein the quantum dots are engineered so as to absorb a significant percentage of photons above bandgap. The bottom layer is a lower band gap layer comprised of quantum dots in polymer, wherein the quantum dots in the second layer are engineered so as to absorb photons not absorbed in the top layer, thus increasing total percentage of absorbed photons. Photovoltaic cells are located below the layers at the bottom of the cells or at the edges of the cells. The sides and lower surfaces of the cells may include reflective surfaces as discussed further herein. Reflection losses from the top surface thereof may be minimized using a broadband anti-reflective coating (AR) on the surface.
    • 叠层发光太阳能聚光器包括两个分开的吸收/发射单元,每个单元具有发光体型材料层,其中顶层是由聚合物中的量子点组成的高带隙层,其中量子点被工程化以吸收 在光隙以上的光子的百分比很大。 底层是由聚合物中的量子点组成的低带隙层,其中第二层中的量子点被工程化以吸收未被吸收在顶层中的光子,从而增加吸收的光子的总百分比。 光伏电池位于细胞底部或细胞边缘的层之下。 单元的侧面和下表面可以包括如本文进一步讨论的反射表面。 使用表面上的宽带抗反射涂层(AR)可以使其顶表面的反射损失最小化。
