Abstract: A system for fabrication of a photovoltaic structure is provided. During fabrication, the system can deposit a doped amorphous Si layer on a first surface of a crystalline Si substrate; and deposit, using a physical vapor deposition machine, a transparent conductive oxide layer on the doped amorphous Si layer. The deposited transparent conductive oxide layer can include In2O3 doped with TiO2 and Ta2O5, and depositing the transparent conductive oxide layer can involve maintaining the Si substrate at a temperature below 130° C. The system can further deposit a metallic layer on the transparent conductive oxide layer, and anneal the transparent conductive oxide layer.

Abstract: A low-reflection-loss low-angle-sensitive colored photovoltaic (PV) module is described. This colored PV module includes a transparent substrate; an array of solar cells encapsulated between a top encapsulation sheet and a bottom encapsulation sheet; and a color filter structure embedded between the top encapsulation sheet and the transparent substrate and configured to cause wavelength-selective reflections of incident light received by the colored PV module. Moreover, the transparent substrate includes a flat front surface configured to receive the incident light and a texture back surface configured with an array of features. The color filter structure is formed on the textured back surface of the transparent substrate to create a textured interface between the textured back surface and the color filter structure.
