Winaico enters back-contact segment with 480 W solar module
The Taiwanese manufacturer has announced its WST-480BDX54-B2 Ultra Black Glass-Glass for the European market. It features an efficiency of 23.5%.
Key PV innovations often originated outside solar sector
Research from the Massachusetts Institute of Technology highlights 81 unique innovations across a diverse range of research efforts and industries that have impacted PV system costs since 1970, the majority of which originate from outside the sector.
Indoor perovskite solar cell built with triple passivation strategy achieves 37.6% efficiency
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.
New research shows cast mono wafers are still far from commercial maturity
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.
JinkoSolar presents 475 W TOPCon dual-glass solar panel with 23.77% efficiency
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 launches new heat pump for residential, light commercial use
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.
New research warns of unexpected UV-induced degradation in TOPCon solar cells from invisible light
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.
Lyten to acquire Northvolt’s $5 billion battery assets in Sweden and Germany
US startup Lyten has stepped up again to buy Northvolt’s Swedish and German assets, continuing its takeover of the failed battery giant’s $5 billion manufacturing empire. The move marks a major shift in Europe’s battery landscape.
China wafer, polysilicon prices climb 33% since early July
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Scientists build bifacial CIS solar cell with record efficiency, power density
Researchers in South Korea have demonstrated a lower temperature process for bifacial copper, indium, selenium (CuInSe₂) solar cells with a rear-side efficiency of 8.44% and 15.30% on the front. The device has been developed for applications in tandem solar cells.
