Meyer Burger is working with several research institutes in Switzerland and Germany to integrate perovskite tandem technology into its manufacturing processes.
Australian researchers patent additive for perovskite’s stability problem
University of New South Wales (UNSW) researchers in Australia have discovered a low-cost way to stabilize perovskite solar cells with a triple function additive. Perovskite cells have shown the best stability results with it so far.
Inverted perovskite solar cell with 22.15% efficiency, 83.92% fill factor
Chinese scientists have used daminozide as an interlayer and additive to make a perovskite solar cell with a p-i-n structure. It has the highest efficiency and highest fill factor for a polycrystalline, MAPbI 3-based inverted perovskite solar cell to date.
Inverted perovskite solar cell with 21.85% efficiency via surface modulator
A UK research group has used surface modulators to reduce non-radiative recombination in perovskite solar cells. They used 2-TEAI organic halide salt to build a cell with high power conversion efficiency and stability.
Flexible all-perovskite tandem solar cell with 23.8% efficiency, improved voltage
A Chinese-Swiss research group claims to have overcome two major challenges for the development of flexible all-perovskite tandem solar cells – voltage losses and the deposition process for the cell’s functional layers. They built a device with a high open-circuit voltage of 2.1 V.
Perovskite solar cell with copper electrode hits 20.1% efficiency
Chinese researchers have developed a new solar cell with a planar n-i-p structure and an indium tin oxide (ITO) substrate. It also has a tin(IV) oxide (SnO2) buffer layer, a perovskite layer, a hole transport layer (HTL), and a layer made of copper. It was able to retain around 92% of its initial efficiency after 1,000 hours.
