Researchers in China have improved interface engineering in perovskite-silicon solar cells by using industrially textured silicon. The result is a highly efficienct tandem device that also showed remarkable stability.

An international research team has constructed an indoor perovksite PV device by using a triple passivation treatment to reduce crystal defects in the perovskite film. The cell achieved remarkable efficiency and was also able to retain 92% of its initial performance after 3,200 h.

A Chinese research team has investigated impurity and defect levels in solar cells based on mono cast wafers and have found that around 30% of the devices present an “excessive” reduction in power conversion efficiency. The scientists concluded that cast monocrystalline silicon will unlikely capture a meaningful market share in the near future.

The Chinese manufacturer said its new IEC 61215-certified rooftop PV module relies on a 30 mm aluminum frame and dual-glass construction that reportedly help it withstand extreme snow loads and wind pressure.

Carrier, a US-based heating solutions provider, has introduced a new heat pump system featuring a cooling seasonal energy efficiency rating (SEER2) of up to 29.7 and a heating seasonal performance factor (HSPF2) of up to 12.2.

OPIS, Wood Mackenzie, and Bernreuter Research have spoken with pv magazine about China’s alleged $7 billion plan to reduce polysilicon oversupply and restore a sustainable pricing environment for the PV supply chain, but opinions remain divided on its feasibility and effectiveness.

Researchers from UNSW have found that invisible light accelerates UV-induced degradation in TOPCon solar cells, producing the same degradation effects as visible light but at a much faster rate. This can lead to significant open-circuit voltage losses and reduce cell efficiency.

Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling technique based on air convection and phase change material that can reportedly increase PV efficiency from 7% to 9% and thermal efficiency by 31.45%.

The Netherlands installed 4.32 GW of solar capacity in 2024, bringing its cumulative total to 28.62 GW by year-end, according to official data.

Researchers in Japan have made another attempt to make agrivoltaics on rice fields technically and economically feasible, despite well-known productivity issues when rice is grown below solar modules. They used double-axis tracking, finding potential with careful management of shading and tilt angles.
