Researchers see microfluidic processing as a pathway to producing flexible printed solar cells on an industrial scale

Researchers at the ARC Centre of Excellence in Exciton Science have identified a way to create Nickel oxide (NiO) films of sufficient quality in solution and at relatively low temperatures of less than 150 degrees Celsius.

NiO is used as an inexpensive hole-transport layer in perovskite solar cells because of its favorable optical properties and long-term stability. However, making high-quality NiO films for solar cells usually requires an energy intensive and high-temperature treatment process called thermal annealing, which is not only costly, but also incompatible with plastic substrates, until now precluding the use of NiO in the proposed manufacture of printed photovoltaics at commercial scale.

Researchers break efficiency record with flipped perovskite-silicon tandems

Researchers from King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, in collaboration with University of Toronto, the National University of Singapore and National Technical University of Athens, have designed monolithic tandem solar cell with power conversion efficiency of 27%, surpassing the previous best reported value of 22% in the same configuration.

Flipped perovskite-silicon tandems break a new record image

The team explains that translating the high power conversion efficiencies of single-junction perovskite solar cells in their classic, non-inverted (n–i–p) architecture to efficient monolithic n–i–p perovskite/silicon tandem solar cells with high current densities has been a persistent challenge due to the lack of low-temperature processable, chemically-insoluble contact materials with appropriate polarity and sufficient optical transparency. To address this, they developed sputtered amorphous niobium oxide (a-NbOx) with ligand-bridged C60 as an efficient electron-selective contact, deposited on the textured-silicon bottom cell.

CubicPV plans $1.1 billion investment under India's PLI scheme

CubicPV is said to be in talks with the Indian government to participate in the performance linked incentives (PLI) scheme for solar equipment manufacturers. CubicPV was established as a result of a collaboration between Hunt Perovskite Technologies and 1366 Technologies.

CubicPV reportedly plans to invest $1.1 billion to set up 10 GW solar wafer and cells manufacturing capacity in India over the next five years. Frank Van Mierlo, CEO of CubicPV, said that the company is planning to bring its innovative products in the solar equipment category, such as wafers and semiconductors, to India.

DoE awards $14 million to form a new center to promote perovskite photovoltaivs

The Department of Energy recently awarded $14 million to form a center, led by Sandia National Laboratories, to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels’ lifetimes.

Perovskite-based photovoltaic technologies still have several challenges to overcome before they can compete against conventional solar panels. The Perovskite Photovoltaic Accelerator for Commercializing Technologies Center aims to offer solutions to these challenges.

Researchers 3D print perovskite-based high-resolution display pixels

A team of researchers from Hong Kong University and the Korea Electrotechnology Research Institute (KERI) have used 3D printing to create nanoscale display pixels made of perovskite.

Last year, the same group of scientists used liquid inks and direct ink writing to fabricate display pixels capable of emitting light. Now, turning their attention to perovskites, the researchers believe they can achieve even greater brightness levels and higher resolution displays using a similar deposition-based 3D printing technique.
