One embodiment can provide a photovoltaic roof tile. The photovoltaic roof tile can include a transparent front cover, a transparent back cover, and a plurality of polycrystalline-Si-based photovoltaic structures positioned between the front cover and the back cover. A respective polycrystalline-Si-based photovoltaic structure has a front surface facing the front cover and a back surface facing the back cover. The photovoltaic roof tile can further include a paint layer positioned on a back surface of the back cover facing away from the front cover. A color of the paint layer substantially matches a color of the front surface of the respective polycrystalline-Si-based photovoltaic structure.

System and method for improving color appearance of solar roofs

A wafer carrier for carrying solar cell wafers during a deposition process is described. The carrier is coated with pyrolytic carbon, silicon carbide, or a ceramic material, and is adapted to receive and support the wafers.

One embodiment of the present invention can provide a system for fabricating a photovoltaic structure. During fabrication, the system can deposit a first passivation layer on a first side of a Si base layer of the photovoltaic structure using a static chemical vapor deposition process. The static chemical vapor deposition process can be performed inside a first reaction chamber. The system can then transfer the photovoltaic structure from the first reaction chamber to a second reaction chamber without the photovoltaic structure leaving a common vacuum space comprising both reaction chambers, and deposit a second passivation layer on the first passivation layer using an inline chemical vapor deposition process. The inline chemical vapor deposition process can be performed inside the second reaction chamber.
