All-perovskite tandem solar cell based on tin-lead perovskite achieves 27.8% efficiency

Scientists in the United States have fabricated an all-perovskite tandem solar cell that reportedly shows reduced interfacial energy loss in the cell’s top device. It was built with a hole transport layer based on a compound known as P3CT that was doped with lead iodide.

Residential PV power forecasting method based uniquely on direct radiation

Researchers in Spain have created a novel PV forecasting method that uses only direct radiation as a parameter. They found it to be “comparable, if not superior” to four established forecasting techniques. The method could help homeowners with PV systems decide when to use electricity-intensive appliances and cleaning systems.

All solar cell efficiencies at a glance – updated

The research group led by Professor Martin Green has published Version 64 of the solar cell efficiency tables. There are 19 new results reported in the new version.

AEG unveils hybrid inverters for high-voltage PV systems

The new three-phase hybrid inverter series includes five versions with power ratings of 6 kW to 15 kW. They feature efficiencies of up to 98.2% and a maximum input voltage of 1,000 V.

pv magazine interview: ‘Nobody is making money right now’

As part of our Intersolar 2024 interview series, pv magazine spoke with Bill Mulligan, CEO of Singapore-based IBC solar module maker Maxeon. He states the IBC technology will remain competitive despite overcapacity and dropping modules prices and says Maxeon may enforce intellectual property rights with all existing and new back contact competitors that are allegedly utilizing its technologies.

‘Module prices surprisingly keep going down’

As part of our Intersolar 2024 interview series, pv magazine spoke with Yana Hryshko, head of Solar Supply Chain Research for Wood Mackenzie, about overcapacity, declining panel prices and expected PV demand for the next years. She revealed that Chinese module procurement schemes are currently seeing unprecedented, “ridiculously” low bids, but she also noted that the $0.08/W threshold may now be difficult to exceed. Hryshko also expects many manufacturers to backpedal on previously announced capacity expansion plans and renegotiate module supply contracts.

List of top solar module manufacturers led by JA Solar, Trina Solar, Jinko Solar

Wood Mackenzie says that JA Solar has taken first place on its list of solar panel manufacturers. Nine of the first 12 positions are held by Chinese manufacturers, seven of them could surpass 100 GW of capacity by 2027, and eight are self-sufficient in cell capacity, according to the research firm.

Concentrator photovoltaic module based on surface mount technology

A research group in Canada has optimized the performance of concentrator photovoltaics by using the so-called surface-mount technology for thermal management. The CPV module prototype utilizes four non-interconnected III-V germanium cells, a Fresnel lens, and a transparent glass printed-circuit board.

Longi presents 24.4%-efficient 660 W HPBC solar panel

Intended for applications in utility-scale PV projects, the new Hi-MO 9 module is available in eight versions with power output ranging from 625 W to 660 W and power conversion efficiency spanning from 23.1% to 24.4%.

Bosch unveils water source heat pumps for residential, commercial applications

Bosch Home Comfort has presented two new heat pumps series that can be used for both retrofits and new buildings. Both products have a size of a size of ½ to 6 tons and a coefficient of performance of up to 4.9.
