perovskite

In the final days of the year, PV Tech is looking back at the solar sector in 2023, including the COP28 climate conference in Dubai.

PV Tech Premium spoke with Martin Green on n-type technology, China's solar dominance, perovskite and promising markets.

As the industry leaves behind p-type technology, most module manufacturers have either chosen tunnel oxide passivated contact (TOPCon) or heterojunction to jump towards n-type modules, with some opting for back contact (BC) cells to transition towards the new technology.

LONGi has developed a crystalline silicon-perovskite tandem solar cell with a power conversion efficiency of 33.9%, the highest on record.

Scott Graybeal, CEO of Caelux, writes on the market opportunity for perovskite development in the US, along with its challenges for market implementation.

The Australian Renewable Energy Agency (ARENA) has committed AU$358 million (US$227.8 million) to new projects during the year from 1 July 2022 to 30 June 2023, while it has also assigned AU$41.5 million for ultra low cost solar, a new focus since last year.

City University of Hong Kong has announced an improvement of perovskite solar cells as a research team engineered a type of self-assembled monolayer and anchored it on a nickel oxide surface as a charge extraction layer.

Large PV manufacturers committing to perovskites is an encouraging sign for the perovskite sector, according to a Rethink Energy report.

Fraunhofer ISE has developed a perovskite-silicon triple-junction solar cell, which boasts a conversion efficiency of “over 30%”.

California-based perovskite solar startup Caelux has closed US$12 million in Series A3 financing to support its factory expansion in Baldwin Park, California, research and development (R&D) and eventual product launch.
