摘要

Certain embodiments include interferometrically tuned photovoltaic cells wherein reflection from interfaces of layered photovoltaic devices coherently sum to produce an increased field in an active region of the photovoltaic cell where optical energy is converted into electrical energy. Such interferometrically tuned or interferometric photovoltaic devices (iPV) increase the absorption of optical energy in the active region of the interferometric photovoltaic cell and thereby increase the efficiency of the device. In various embodiments, one or more optical resonant cavities and/or optical resonant layers is included in the photovoltaic device to increase the electric field concentration and the absorption in the active region.
