US trends for residential solar finance, equipment, maintenance

A new US solar installer survey covers typical loan terms, top equipment brands, and what to expect from system maintenance services.

Carbon-based perovskite solar cell without hole transport layer achieves 14.15% efficiency

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.

All-perovskite tandem PV cell based on carboranes hits 27.2% efficiency

Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.

US, Canada ramp up solar glass plans

With PV module capacity ramping up, glass suppliers have been investing in new solar glass production capacity. As in India and China, new facilities are popping up in North America, with unique twists to ensure competitiveness, such as using recycled material.

The Hydrogen Stream: Adnoc delivers low-carbon ammonia to Japan

Adnoc has delivered the world’s first certified bulk commercial shipment of low-carbon ammonia to a client in Japan, while Plug Power has agreed to supply a 3 GW electrolyzer in Australia.

U.S. scientists demonstrate 25%-efficient perovskite-cadmium tandem solar cell

The researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.

US solar tariffs and the shadow of larger trade measures

Intensified trade measures against China via higher tariffs on imported solar and battery cells are a significant policy step, but the impact is clouded by global manufacturing shifts, price decreases and looming US Department of Commerce trade complaints.

China’s solar dominance set to continue amid price slide

With solar module oversupply triggering a price freefall in 2023 and no recovery in sight, market consolidation, inventory pile-up, technology shifts, and challenges to reshoring PV manufacturing are set to affect all levels of the solar supply chain.
