BIPV

German solar company Polarstern sees many performance-enhancing effects when photovoltaic systems are combined with green roofs. These are provided by cooling, dust absorption and reflective behavior, which are favored by the plants on the roof.

The phovoltaic sunshade was deployed on the facade of a factory owned by Polish aluminum system provider Aliplast. The movement of the PV blinds is regulated by a controlling system linked to a weather station installed on the roof.

The solar tiles were deployed on a conference center in Glücksburg, Germany. In addition to PV, the building also uses solar thermal energy and biomass to cover heat demand. The power generated by the PV array is utilized entirely for self-consumption.

Soltech Energy has installed a 60 kW solar facade on the wall of a garage in Sweden that hosts 300 EV-charging posts. It features a steel structure to facilitate the flow of air.

Scientists Ayodhya Tiwari and Daniel Lincot recently spoke to pv magazine about the future of copper indium gallium selenide solar tech, which could play a key role in providing flexible, lightweight products in the building-integrated PV segment.

Developed by a German group of scientists, the panels are considered an ideal solution for aesthetically demanding applications in buildings with stone facades. Although their power yield is more than halved compared to conventional modules, the modules can also be used as partial shading walls or semi-transparent roof elements.

Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.

Necessity, as it’s said, is the mother of invention. For architect Samira Jama Aden, who plays a central role at Helmholtz-Zentrum Berlin’s BAIP consultancy for building-integrated photovoltaics (BIPV), the need for solar to be part of our built environment is becoming unavoidable. And for Aden, her mission is personal.

Australian company ClearVue Technologies says it has a fully transparent, scalable, industry-ready solar window in production. It claims that it’s now just 18 months away from cracking 5% efficiency, thanks to a research partnership.

Both products are based on 22%-efficient CIGS solar cells and are manufactured in Asia. One of the two devices has a flat design and power output of 80 W and a second product features a nominal power of 30 W and an undulating design.
