Dyesol awarded $0.5 million grant to pursue high efficiency, low cost solar cell

Dyesol awarded $0.5 million grant to pursue high efficiency, low cost solar cellAustralia-based Dyesol has been awarded a $449,000 grant from the Australian Renewable Energy Agency (ARENA) to commercialize an innovative, very high efficiency perovskite solar cell.

ARENA has stated that the funding would enable Dyesol to create a roadmap setting out the steps needed to take its perovskite solar cell technology from the lab to a commercially available product. Dyesol will map out the techniques and requirements for working towards scalable manufacturing of high-quality, uniform perovskite cells that achieve efficiency, durability and stability targets.

As declared, Dyesol is initially aiming for a delivery cost benchmark of US 10 cents per kWh, putting perovskite solar PV cells on par with current benchmarks achieved by silicon solar PV. This would be a considerable achievement given silicon PV’s maturity as a technology, and provides further scope for reduction in the cost of energy as manufacturing volumes grow.

Graphene as a front contact for silicon-perovskite tandem solar cells

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. Perovskite materialsTechnical / researchAbove are World’s first 2D sheets of organic-inorganic hybrid perovskites grown from a solution web publication,Hope can help you.

Researchers at the Helmholtz-Zentrum Berlin (HZB) developed a process for coating perovskite layers with graphene for the first time, so that the graphene acts as a front contact.

A traditional silicon absorber converts the red portion of the solar spectrum very effectively into electrical energy, whereas the blue portions are partially lost as heat. To reduce this loss, the silicon cell can be combined with an additional solar cell that primarily converts the blue portions and a particularly effective complement to conventional silicon is perovskite. However, it is normally very difficult to provide the perovskite layer with a transparent front contact. While sputter deposition of indium tin oxide (ITO) is common practice for inorganic silicon solar cells, this technique destroys the organic components of a perovskite cell.

The HZB scientists have found an innovative solution to that problem, in a process that covers the perovskite layer evenly with graphene – forming an extremely thin film that is highly conductive and highly transparent. For that to happen, the researchers first promoted growth of the graphene onto copper foil from a methane atmosphere at about 1000 degrees Celsius. For the subsequent steps, they stabilise the fragile layer with a polymer that protects the graphene from cracking. In the following step, they etch away the copper foil. This enables the transfer of the protected graphene film onto the perovskite. This is normally carried out in water, where the graphene film floats on the surface and is “fished out” by the solar cell. However, in this case this technique does not work, because the performance of the perovskite degrades with moisture. Therefore it was necessary to find another liquid that does not attack perovskite.

Tests proved that the graphene layer acts as an ideal front contact in several respects. Thanks to its high transparency, none of the sunlight鈥檚 energy is lost in this layer. But the main advantage is that there are no open-circuit voltage losses, that are commonly observed for sputtered ITO layers. This increases the overall conversion efficiency. The solution is also comparatively simple and inexpensive to implement. The success in implementing graphene in a perovskite solar cell for the first time enabled the scientists to build a high-efficiency tandem device.

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%. When hooked up to charge small coin-sized lithium-ion…

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.

When hooked up to charge small coin-sized lithium-ion batteries, the team achieved a conversion and storage efficiency of 7.8% and maintained it over a number of cycles.

The scientists’ vision is of a system that can be kept at home to refuel cars and, eventually, because perovskite solar cells can be made as a flexible film, they would be on the car itself. The advantage provided by the perovskite cells is that they allow recharging a battery without disrupting the styling of a car too much, unlike large solar panels more commonly associated with solar powered cars.

Dyesol declares perovskite stability breakthrough

Dyesol declares perovskite stability breakthroughAustralia-based organic PV and perovskite solar cell (PSC) developer Dyesol declares a major breakthrough in perovskite stability for solar applications. Stability and durability were among the biggest challenges with which perovskite PVs were faced in recent years, with the material sensitive to moisture contact and high efficiency perovskite cells exhibiting high degradation rates.

Now, Dyesol claims to have made a significant breakthrough on small perovskite solar cells, with “meaningful numbers” of 10% efficient strip cells exhibiting less than 10% relative degradation when exposed to continuous light soaking for over 1000 hours. The cells were encapsulated and tested at full sun intensity for this duration and exhibited relatively low degradation levels, according to the company. Dyesol has not exposed what form of encapsulation was used for the cells tested (as both flexible and traditional glass encapsulation are suitable for PSC applications).

Dyesol stated that this breakthrough encourages it to accelerate development and scale-up their low cost and easily produced PSC technology architecture. The company also adds that the PSC strips that performed well in the accelerated degradation testing are produced using the company’s, “low-cost, scalable, carbon-based PSC architectures.”

Researchers at The Hong Kong Polytechnic University (PolyU) have developed efficient and low-cost semitransparent perovskite solar cells with graphene electrodes. The power conversion efficiencies (PCEs) of this novel invention are around 12% when they are illuminated from Fluorine-doped Tin Oxide bottom electrodes (FTO) or the graphene top electrodes, compared with 7% of conventional semitransparent solar cells.

PolyU researchers used graphene as an electrode material, after creating simple processing techniques for enhancing the conductivity of graphene to meet the requirement of its applications in solar cells. To begin with, the conductivity of graphene was dramatically improved by coating a thin layer of conductive polymer that was also used as an adhesion layer to the perovskite active layer during the lamination process. Im addition, the performance of this novel invention is further optimized by improving the contact between the top graphene electrodes and the hole transport layer on the perovskite films.

Thanks to the convenient preparation of the devices, PolyU’s invention can be used for the mass production of the semitransparent perovskite solar cells with printing or roll to roll process. The semitransparent solar cells aims to fill the gap in the market which is not achievable by the existing solar cells dominating the market.
