New research from Switzerland showed that alpine floating PV systems can outperform lowland or ground-mounted counterparts in terms of energy yield and sustainability. The scientists found that the main material-reduction potential of such floating PV installations lies in the resource-intensive mounting system.

Researchers in China have built for the first time an inverted perovskite solar cell relying on a high-entropy hybrid perovskite material. The result is a device with an improved open-circuit voltage and fill factor, due to reduced non-radiative recombinations and optimized interface.

The Saudi research institute said its new four-terminal tandem device has achieved the highest efficiency ever reported for perovskite-based 4-T and triple-junction tandem solar cells to date. The key feature of the cell is the hole transport layer of the top perovskite cell, which was engineered with self-assembled monolayers.

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.

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.

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.

The Chinese manufacturer said its new photovoltaic air conditioner is available in three versions with a cooling capacity ranging from 12.1 kW to 16 kW and a heating capacity of 14 kW to 18 kW. It can be used for both residential and commercial applications.

The new module has a power output of up to 650 W and weighs 29.6 kg. It uses JA Solar’s patented anti-dust frame technology, which reportedly enhances drainage and decontamination performance, thus reducing dust accumulation and avoiding hotspot issues.

The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH). The cell also achieved an open-circuit voltage of 709.5 mV, a short circuit density of 11,355 mA, and a fill factor of 82.04%.

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%.
