The Italian renewable energy company said it will validate Swift Solar’s 28% efficiency perovskite-silicon tandem technology in a utility-scale project.

The Chinese manufacturer said the tandem device was developed through a dual-buffer layer strategy that improves interfacial adhesion while preserving efficient charge extraction. The efficiency result was certified by the US Department of Energy’s National Renewable Energy Laboratory (NREL)

South Korea has allocated KRW 33.6 billion ($22.8 million) for R&D on perovskite-silicon tandem solar technology with a goal of commercializing 28%-efficient modules by 2030, according to the Ministry of Economy and Finance.

Researchers in the United States have developed a photonic curing technique using laser sintering to rapidly heat and cure copper pastes on temperature-sensitive solar cell substrates without causing thermal stress. The process purportedly produces dense, low-porosity copper layers with strong adhesion to indium tin oxide, achieving low bulk and contact resistivity.

A research team in Spain has built what it claims to be the world’s most efficient perovskite solar cell using MXenes or any other type of 2D-materials. The device relies on a Mxene interlayer that suppresses non-radiative recombination and improved charge extraction at the interface between the perovskite absorber and the electron transport layer.

The Japanese technology company is offering three types of space-grade compound solar cell designs for satellites and spacecraft.

UNSW researchers have investigated the impact of electron irradiation on PERC and TOPCon solar cell performance and have identified bulk lifetime degradation as main power loss cause. Their work stresses the need for increasing radiation tolerance in commercial space silicon solar cells.

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.

The quality assurance firm updated its inverter manufacturer financial stability ranking with Kstar Science and Technology, APSystems and Delta Electronics in the top three spots. It reported 19 manufacturers showing “strong financial resilience” based on Altman-Z scores.

In a new scientific paper, the Chinese solar manufacturer explained that the 27.81%-efficient hybrid interdigitated back-contact cell it unveiled in April is based on passivated tunneling contacts and dielectric passivation layers, while also incorporating both n-type and p-type contacts.
