Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.

Shunt Passivation Method for Amorphous Silicon Thin Film Photovoltaic Modules
InactiveUS20070068571A1Electrical shunting defectIncrease output powerClimate change adaptationPhotovoltaic energy generationOptical transparencyEngineering
A method for reducing shunt-related defects is described for hydrogenated amorphous silicon (a-Si:H) thin film photovoltaic modules with thin active a-Si:H absorber as required by building integrated photovoltaic windows and sun-roofs with adequate transmission of sunlight. Without shunt-passivation, p-i-n type large area photovoltaic modules with very thin a-Si:H i-layer will suffer excessive performance, yield, and reliability losses due to electrical shorting through i-layer defects. Wide-bandgap a-Si:H based alloy films of sufficient resistivity are deposed between the active solar cell and the conductive back electrode to provide a barrier to leakage current flow. Such a-Si:H based barrier films of high optical transparency are dummy films that do not directly contribute to energy conversion. The shunt-passivation films are entirely produced by the same conventional manufacturing process for a-Si:H photovoltaic devices without invoking complicated or exotic materials or procedures proposed in prior arts.
