Modules & Upstream Manufacturing

Researchers at the University of Bologna carried out crash simulations to qualify a novel solar powered 350 kg passenger vehicle for the next edition of the 3,000 km Bridgestone World Solar Challenge (BWSC) across the Australian continent.

Prices for tunnel oxide passivated contact (TOPCon) solar panels continue to fall. pvXchange.com founder Martin Schachinger explains how this will affect the sale of PV modules based on passivated emitter and rear cell (PERC) cells.

India’s Pahal Solar has launched n-type tunnel oxide passivated contact (TOPCon) glass-backsheet modules with peak power outputs of 560 W to 595 W and efficiency ratings ranging from 21.68% to 23.03%.

Researchers in Niger have proposed to use photovoltaic energy to power the operations of evaporative cooling greenhouses. The proposed experimental solution uses locally made pads and is reportedly able to compete with commercial counterparts.

The tandem solar cell is based on a perovskite top cell treated with an additive known as 2,3,4,5,6-pentafluorobenzylphosphonic acid (pFBPA), which reportedly improves its power conversion efficiency and fill factor. The tandem device also integrates a bottom heterojunction silicon cell made with a 190-μm-thick, 2 Ω.cm, n-type, float-zone, shiny-etched monocrystalline wafer.

China National Offshore Oil Corp. (CNOOC) says it has bought 790 MW of solar modules from Yingli at $0.12/W through a procurement process.

Scientists in China have fabricated a prototype of a PV system integrating phase change materials, a thermoelectric generator and thermal collectors. The three technologies are intended to cool the solar panel and increase its power generation efficiency.

Silfab Solar is one of seven recipients of US Department of Energy (DoE) funding for projects that will rely on dual-use PV technologies to electrify buildings, decarbonize the transportation sector, and reduce land-use conflicts.

The Durable Module Materials consortium (DuraMAT) announced in its latest annual report the availability of new PV forecasting tools, and new research results towards the goal of more reliable PV modules.

Researchers in China have outlined a new surface engineering strategy to build low-cost solar cells without a hole transport layer. The devices were treated with benzoylcholine halide to reduce non-radiation recombination and achieved remarkable efficiency and stability.
