Abstract

A plurality of dichroic filters are included in multifunction photovoltaic cells to increase efficiency. For example, in a multi-junction photovoltaic cell comprising blue, green, and red active layers, blue, green, and red dichroic filters that reflect blue, green, and red light, respectively, may be disposed proximal to the blue, green, and red active layers to reflect back light not absorbed on the first past. The dichroic filters may be used to demultiplex white light incident on the PV cell and deliver suitable wavelengths to the appropriate active layer, e.g., blue wavelengths to the blue active layer, green wavelengths to the green active layer, red wavelengths to the red active layer. The PV cell may additionally be interferometrically tuned to increase absorption efficiency. Accordingly, optical resonant layers and cavities may be employed in certain embodiments.
