Germany’s Fraunhofer Institute for Solar Energy (ISE) has advanced vehicle-integrated PV (VIPV) technology by installing solar cells directly onto a standard sheet-metal car hood. The researchers placed a 115 W prototype array on the hood of a Volkswagen with a specialized lamination process.
Sono Motors has equipped its first bus with its PV retrofit solution, featuring 16 semi-flexible rooftop solar modules to feed 1.4 kW of output into the vehicle’s battery system.
Researchers in Spain assembled an experimental solar simulator for vehicle-integrated and curved solar panels. They found that the measurements of the short-circuit current of the cells followed the ideal cosine response of the curvature with differences lower than 0.5%.
Toyota says it will combine EneCoat’s perovskite solar cells and its own in-vehicle technologies for solar panels. Enecoat has developed a perovskite module conversion efficiency of 19.4%.
A new three-year pilot project will assess the efficiency of vehicle-integrated PV and verify it with on-the-road monitoring and testing. The goal is to predict the charging infrastructure needed for electric vehicles with PV modules.
Scientists in Spain have developed a transparent solar cell with an average visible transmittance of up to 66%. The device could be used for ubiquitous device functionalization, including indoor PV and agrivoltaics.
Bonna Newman, program manager at TNO, speaks to pv magazine about the road forward for vehicle-integrated PV, which will likely remain a niche over the short term, despite recent industrial developments. Several companies have started production, but high-volume output and the potential of other PV technologies beyond crystalline silicon remain key challenges for the future of vehicle-integrated solar.
Developed by the French research institute Liten, the prototype kit consists of a 145 W photovoltaic panel, a magnetic rear panel, and an MPPT charge controller. It also includes a battery and a micro-inverter that can be used to inject the stored energy into the grid when the vehicle is recharged.
Canadian startup Capsolar claims its flexible solar modules can be adapted to any type of low-speed electric vehicle with no extra modification and custom work. The panels have an efficiency of 21.3%.
Commercially printed solar cell technology developed by the University of Newcastle is being put to the test to power an electric vehicle’s 15,097-kilometre journey around the entire coastline of Australia.
