perovskite solar cells

NREL’s new solar window darkens in the heat of the sun, producing electricity via embedded perovskite film. The tech is based on formamidinium-based metal halide perovskite, an inherently thermochromic material exhibiting significant optical changes.

Researchers in Singapore have developed a 6.4 cm2 solar module based on co-evaporated methylammonium lead iodide (MAPbI3). They claim that the panel is a step forward in the industrialization of perovskite mini-modules.

Australian researchers have made a significant discovery in the fight against light-induced phase segregation in next-generation PV cells.

Born from an Oxford research group, the startup is looking to make its name by developing all-perovskite tandems – something no other company has done.

A US study has suggested the raised energy yield of bifacial perovskite devices effectively means they could have a lower environmental impact than conventional crystalline cells. The researchers considered single-junction cells with high and low bandgaps and similar, multi-junction devices with two and four-terminal structures.

The U.S. based researchers have developed a new wide-bandgap perovskite layer – called Apex Flex – which they claim is able to withstand heat, light, and operational tests, and at the same time provide a reliable and high voltage. With this material, they built tandem solar cells with 23.1% power conversion efficiency on a rigid substrate, and 21.3% on flexible plastic.

Scientists at the École Polytechnique Fédérale de Lausanne have developed a new ‘chemical innovation’, for the deposition of perovskite solar cells onto a substrate. The method is shown to produce cells at better than 23% efficiency, that remained stable after 500 hours testing at a raised temperature.

Scientists in Hong Kong have developed a cell they say retains more than 90% of its initial efficiency under accelerated testing conditions. The device is based on two-dimensional metal-organic frameworks.

The Institute for Solar Energy Research Hamelin (ISFH), the Karlsruhe Institute of Technology (KIT) and the Institute for Materials and Components in Electronics at the University of Hannover, as well as Centrotherm, Singulus, Meyer Burger and Von Ardenne are involved in a research project aimed at achieving a 27% conversion efficiency for silicon solar cells based on perovskite.

National Taiwan University and Taiwanese PV production equipment provider E-Sun Precision Industrial Co. have developed equipment to produce different kinds of perovskite cells with varying chemical compositions. The first trials achieved 14.3% conversion efficiency rates.
