Abstract
Devices incorporating an interferometric stack in a photovoltaic device and method of manufacturing a photovoltaic device comprising an interferometric stack. In one example, a photovoltaic device includes a photovoltaic active layer, an absorber layer, and a first optical resonant cavity layer. The optical resonant cavity layer is disposed between the absorber layer and photovoltaic active layer forming an interferometric modulator. The interferometric modulator is configured to reflect a uniform color. In another example, a method of manufacturing a photovoltaic device includes depositing a photovoltaic active layer on an interferometric stack. The interferometric stack can include an absorber layer and a first optical resonant cavity. The photovoltaic active layer is deposited on the optical resonant cavity and the formed photovoltaic device is reflects a uniform color.
