MONOLITHIC IMOD COLOR ENHANCED PHOTOVOLTAIC CELL

摘要

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 410 includes a photovoltaic active layer 301, an absorber layer 201, and a first optical resonant cavity layer 202a. The optical resonant cavity layer 202a is disposed between the absorber layer 201 and photovoltaic active layer 301 forming an interferometric modulator 200. The interferometric modulator 200 is configured to reflect a uniform color. In another example, a method of manufacturing a photovoltaic device includes depositing a photovoltaic active layer 301 on an interferometric stack 401. The interferometric stack 401 can include an absorber layer 201 and a first optical resonant cavity 202a. The photovoltaic active layer 301 is deposited on the optical resonant cavity 202a and the formed photovoltaic device is reflects a uniform color.
