Brown University to lead $4 million solar cell research grant

World’s first 2D sheets of organic-inorganic hybrid perovskites grown from a solution

Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory have succeeded in growing atomically thin 2D sheets of organic-inorganic hybrid perovskites from a solution. The sheets are claimed to be of high quality and large in area. The scientists state that this is the first example of 2D atomically thin nanostructures made from ionic materials and that the results of this study open up opportunities for fundamental research on the synthesis and characterization of atomically thin 2D hybrid perovskites and introduce a new family of 2D solution-processed semiconductors for nanoscale optoelectronic devices, such as field effect transistors and photodetectors.

A team led by Brown University researchers has been awarded $4 million by the National Science Foundation to study perovskite solar cells. The research will be performed in partnership with the University of Nebraska–Lincoln (UNL) and Rhode Island College (RIC).

The research will aim at better understanding the basic science behind these solar cells, looking for ways to develop new technologies based on that understanding, and investigating scalable production methods that could one day bring perovskite solar cells to market. Another issue the researchers will look to address is the fact that the best performing perovskite solar cells contain lead. The team will look for lead-free perovskite compositions that work equally well.

The grant also includes a substantial outreach and education effort. Students and researchers involved in the project will go to middle and high schools to talk about energy efficiency and green technologies. The project also includes the development of an online college course on solar technologies aimed at people who are interested in entering the green workforce. The grant also provides funding for graduate students and for undergraduate research opportunities.

The award, which will be paid over four years, was made through the National Science Foundation’s Experimental Program to Stimulate Competitive Research (EPSCoR) program.

Perovskite solar cells may recharge electric cars’ batteries

Scientists at Case Western Reserve University that have been experimenting with the use of small perovskite solar cells to help recharge the batteries of electric cars state that they have found a system that performs better than any other. They wired four perovskite solar cells in series to directly photo-charge lithium batteries with 7.8% efficiency. The researchers say that they have found the right match between the solar cell and battery. The coupling appears to have outperformed all other reported pairings of photo-charging components and compatible batteries or supercapacitors. They have created cells with three layers converted into a single perovskite film and then wired four of the 1 mm square cells in series, achieving a solar-to-electric power conversion efficiency of 12.65%.
