Perovskite

Mitsui Home and Tokyo Gas have revealed plans to deploy Japan’s first combined on-site and virtual solar power purchase agreement (PPA), cutting factory emissions and maximizing rooftop energy use.

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.

The Chinese manufacturer said the cell uses a multifunctional organic ammonium salt to improve interfacial engineering between the perovskite absorber and the electron transport layers. The device also achieved 24.5% efficiency when scaled up to a 1 cm² active area.

Researchers in China have developed an inverted perovskite solar cell approaching the 27% efficiency threshold. The device incorporates a specially designed self-assembled monolayer that passivates perovskite defects and enhances efficiency.

Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.

US-made perovskite tandem cells from Swift Solar were used in a US Department of Defense hybrid microgrid as part of a recent cybersecurity demonstration.

A Chinese research group claims to have achieved remarkable efficiency and stability in a solar cell based on a perovskite absorber incorporating MXene, a novel type of 2D material known for its excellent conductivity, chemical stability, and thermal resilience. The device reportedly retained 80% of its initial efficiency after 500 hours.

Conceived by scientists in China, the cell was built with an alkaline treatment that modulates efficiently the perovskite quantum dots surface chemistry. The device reportedly achieved the highest power conversion efficiency ever reported for this kind of solar cells.

Three US manufacturers actively working to commercialize their respective perovskite-silicon tandem technologies make the case for tandem modules. CubicPV, Caelux and Swift Solar argue a commercial future for perovskites is inevitable, and they tell pv magazine the current policy environment could work in the technology’s favor.
