perovskite solar cells

A research team in India has investigated the use of highly conductive transparent electrodes based on amorphous indium zinc made with a room temperature process in perovskite solar cells. The devices could be used in tandem and building-integrated PV applications.

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.

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.

Researchers at Nanyang Technological University have demonstrated a method to integrate chemically inert low-dimensional interface materials into the fabrication of inverted perovskite solar cells. Their prototype solar cells retained over 93% of the initial power conversion efficiency of 25.1% after 1,000 hours of operation, and 98% after 1,100 hours at 85 C.

The Japanese imaging and electronics company said tests of its perovskite solar cell technology will be conducted in a demonstrator system aboard an unmanned cargo spacecraft operated by Japan Aerospace Exploration Agency.

J-Power announced an investment in US-based perovskite solar specialist Active Surfaces, along with plans to pilot product tests.

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.

The U.S. startup said the 30 x 30 cm perovskite solar cell device featured its tin oxide electron transport material produced in a sheet-to-sheet slot die coating process.

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.
