PHOTOVOLTAIC DEVICE WITH SURFACE PERTURBATIONS CONFIGURED FOR RESONANT AND DIFFUSIVE COUPLING

摘要

Photovoltaic devices are contemplated where TCO layers of the device are provided with a distribution of resonant coupling periodicities Λ_R while the glass substrate of the device is provided with a distribution of diffusive coupling periodicities Λ_D. The respective surface textures defining these periods are superimposed at an interface with the photoelectric conversion layer and collectively define a frequency-dependent power spectral density inversion in the device. Additional embodiments are disclosed and contemplated.
