GRAPHENE-BASED INTERCONNECTS FOR STABLE DYE-SENSITIZED SOLAR MODULES

Within the EU Graphene Flagship Project, through the collaboration between the C.H.O.S.E. and the "Graphene Cambridge Center" of the University of Cambridge (UCAM), founded and directed by Prof. Andrea C. Ferrari, who is also the Science and Technology Officer and the Chair of the Management Panel of the Graphene Flagship (one of the largest research initiatives ever funded by the European Commission), the first DSSC (Dye-Sensitized Solar Cell) PV (Photo-Voltaic) module, based on Graphene printed interconnects, was realized.

Thanks to these interconnects, corrosion issues that affect the typical silver grids of the DSSC modules have been fixed, thus increasing the structural stability of these devices.

Graphene paste was realized and fabricated via microfluidization at the Graphene Cambridge Center. Graphene-based interconnects of the DSSC module have also allowed to increase the Power Conversion Efficiency (PCE) calculated on Aperture Area, up to 12% with respect to silver-based ones. This result, combined with the greater stability of the devices once compared to the standard ones (made of silver), further rolls out the DSSC technology in the BIPV (Build Integrated Photo-Voltaic) sector and in indoor application.

The obtained results are published in ACS Publications, available at the following link:

Operational stability of perovskite solar cells (PSCs) is rapidly becoming one of the pressing bottlenecks for their upscaling and integration of such promising photovoltaic technology. By using a Polaron Arrangement strategy, we demonstrated stable PSCs with typical power conversion efficiencies above 20%, retain more than 90% of the initial efficiency after 1080 hours thermal stress at 85 ˚C and 87% of initial efficiency after 160 hours exposure against 1 sun light soaking. By using this strategy, we advanced the efficiency of perovskite solar modules beyond 17% on an active area of 43 cm2, keeping above 90% of the initial efficiency after 800 hours thermal stress at 85 ˚C. These results, obtained in ambient conditions, pave the way toward the industrialization of PSC-based photovoltaic technology.

DEVELOPMENT OF A COLOUR - SENSITIVE INKJET-PRINTED PIXELATED ARTIFICIAL RETINA MODEL AND ITS STUDY VIA AN OPTOELECTRONIC DEVICE | PRESS RELEASE

11 December 2020

Development of a colour-sensitive inkjet-printed pixelated artificial retina model and its study via an optoelectronic device

 

Around 300 million people worldwide are visually impaired. In recent years, photosensitive organic electronic materials have been shown to be a very promising tool for transducing light stimuli to non-functioning retinas. An international interdisciplinary team from four institutes developed a colour-sensitive artificial retina model using polymer semiconductors. These are processable as inks which enabled pixelatation by depositing each polymer dot by inkjet-printing. Three types of polymer semiconductors, with spectral absorbance curves emulating those of rods, and of cones which provide colour sensitivity, were deposited in a concentric layout simplifying the anatomical human retinal scheme. The team verified that the phototransduction process from the artificial retina to a biological electrolyte solution imitating extracellular fluids found in our tissues produced electrical signals compatible with those found in retinas through a novel closed sandwich-type optoelectronic device. Biocompatibility of the materials was also verified. The bio-hybrid device is compact, easy-to-handle, transportable, with controllable size and requires a small amount of bio-electrolyte thus permitting use of tools typically found in an electronic-engineering/physics/chemistry laboratory. The density of the artificial photoreceptors was ∼11000 pixels/cm2 and the corresponding spatial resolution was 267 dpi (dots per inch), with pixel diameters of 95 micrometres comparable to that of a human hair.
Results are published in “Colour‑sensitive conjugated polymer inkjet‑printed pixelated artificial retina model studied via a bio‑hybrid photovoltaic device” article in Scientific Reports at https://rdcu.be/cbQ6g

A Special Issue on "ADVANCED HYBRID AND COMPOSITE CRYSTALS FOR SOLAR FUELS"

Various technologies based on photochemical, photobiological, thermochemical, photoelectrochemical, and photovoltaic-electrochemical integration have been utilized for solar fuel production. However, there are numerous scientific challenges to developing these technologies, including finding suitable materials and hybrid/composite structures to improve light absorption, developing more efficient and stable catalysts and thin films, enhancing selectivity, minimizing interfacial losses, and resisting degradation. Accordingly, the utilization of some advanced organic/inorganic hybrid and composite crystalline compounds and relative thin films such as 2D/3D structures, plasmonic core-shell, carbon-based nanostructures, porous nanostructures, molecular catalysts, metal-organic and zeolitic imidazolate frameworks, polyoxometalates, hybrid conjugated polymers, and hybrid biomimetics can markedly improve the performance of solar fuel technologies toward industrialization.

HIGH-EFFICIENCY INDOOR PEROVSKITE PHOTOVOLTAICS ON ULTRA-THIN GLASS | PRESS RELEASE

29 April 2020

High-Efficiency Indoor Perovskite Photovoltaics on Ultra-Thin Glass

 

A revolution is already under way which includes development of autonomous wireless sensors, low-power consumer electronics, smart homes, domotics and the Internet of Things. All these elements require efficient and easy-to-integrate energy harvesting devices for their power. Indoor photovoltaic (PV) power sources, on ultra-thin curvable substrates, will have the potential to facilitate these technological innovations if they can provide sufficient energy under indoor illumination rather than the sun to the electronic components, while remaining small, convenient and economical. An international team with researchers from University of Rome – Tor Vergata, Universidad Surcolombiana, and the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology has published results in Cell Reports Physical Science which highlights the progress made in achieving efficiencies above 20% under indoor illumination using flexible perovskite solar cells fabricated on ultra-thin glass. The efficiencies obtained represent the highest reported for any indoor photovoltaic cell technology that is flexible and curvable, as well as surpassing by a 60-90% margin the prior best-performing perovskite photovoltaic cells on flexible substrates. Specific powers in Watts delivered per gram of weight (W/g) are 40-55% higher than their counterparts on plastic PET films and an order of magnitude greater than those on rigid glass.
