BIPV

Scientists in China have outlined a new system architecture for vacuum integrated photovoltaic (VPV) curtain walls. They claim the new design can reduce building energy consumption and yield more surplus power generation electricity.

Panasonic is now testing perovskite-based power-generating glass with Japanese property developer Mitsui Fudosan Residential at a new building in Kanagawa prefecture, Japan.

Researchers in South Korea have developed a process to enable colored and flexible, thin film modules suitable for vehicle and building-integrated PV applications. It is reportedly a low-cost process that does not significantly impact power conversion efficiency.

South Korean scientists have developed a new building-integrated photovoltaic (BIPV) solar cell featuring a distributed Bragg reflector (DBR) electrode. This innovation is expected to enhance light scattering and meet aesthetic standards.

Scientists in India have proposed to use solar modules at the end of their lifecycle as a building material for low-cost small housing units. With solar module recycling currently not viable economically, the researchers said their approach makes conventional solar panels into BIPV products without any modifications.

Enfoil is developing a CIGS thin film custom manufacturing business, targeting building-integrated PV applications, such as powering sensors or track & trace sub-systems in trucks. The company is a spinoff of Hasselt University and imec, the Belgian research institute.

Scientists in South Korea have stressed the importance of accurately setting the angle of slat PV blinds to maximize power generation. They found that there is a tradeoff between elevated power yield and self-shading effects in this BIPV technology.

The adoption of building-integrated photovoltaics (BIPV) has been hindered by the complexity of fire safety standards, creating challenges for manufacturers and suppliers. However, efforts such as the IEA PVPS Task 15 report and collaborative research have shed light on the importance of comprehensive guidelines, reliable testing laboratories, and international cooperation.

The National Renewable Energy Laboratory (NREL) conducted a time-motion study and found that retrofitting roof-integrated PV requires 7% less labor than standard solar installations. For new builds, installation times fall by 44%.

Swiss manufacturer Meyer Burger says that in August it hopes to begin distributing its new gray solar tiles, which are already being used in pilot projects.
