Researchers improve the stability of perovskite solar cells with novel encapsulation method

Researchers at CHOSE (Centre for Hybrid and Organic Solar Energy, University of Rome Tor Vergata), BeDimensional, Istituto Italiano di Tecnologia and GreatCell Solar Italia recently addressed the stability issues presented by perovskite solar cells, by developing an industrial encapsulation process based on the lamination of highly viscoelastic semi-solid/highly viscous liquid adhesive atop perovskite solar cells and modules.

The encapsulant reportedly reduces the thermomechanical stresses at the encapsulant/rear electrode interface. The addition of thermally conductive two-dimensional hexagonal boron nitride into the polymeric matrix improves the barrier and thermal management properties of the encapsulant. Without any edge sealant, encapsulated devices withstood multifaceted accelerated ageing tests, retaining >80% of their initial efficiency.

First Graphene, Halocell and QUT secure funding for perovskite PV project

Graphitic materials supplier First Graphene has announced an R&D collaboration with Greatcell Energy, trading as Halocell Energy, and the Queensland University of Technology (QUT) to commercialize perovskite solar cell fabrication. The project has received a Cooperative Research Centers Project (CRC-P) grant worth over AUD$2 million (around $USD1,300,000).

The research and development project is intended to commercialize ultra-low-cost, flexible perovskite solar cell fabrication using Halocell’s roll-to-roll production process at the company’s Wagga Wagga plant, First Graphene said in an announcement. Through the project, First Graphene plans to develop cost-effective graphene-based electrode replacements for high-cost conductor materials, such as gold and silver, used in cell manufacturing.

Greatcell Australia and First Graphene explore graphene enhancements to perovskite solar cells

It was recently reported that Greatcell Australia is working with graphene company First Graphene on graphene enhancements to perovskite solar cell technology.

Greatcell Australia has reportedly established a pilot plant in New South Wales and is in the advanced stages of testing its range of perovskite solar cells (PSCs) with manufacturers around the world. “Greatcell is aiming to modularize their production lines for product flexibility, due in part to the easier assembly and reduced number of steps to produce PSCs compared to silicon solar cells.”

Perovskite solar cells show improved stability and renewable capability with the use of polyvinylpyrrolidone polymer

Researchers from the Hefei Institutes of Physical Science (HFIPS) under the Chinese Academy of Sciences (CAS), University of Science and Technology of China, North Minzu University, Hefei University of Technology, Greece's Institute of Nanoscience and Nanotechnology (INN) and Australia's Greatcell Energy have developed perovskite solar cells with a self-recovery capability and high stability in humid environment by introducing polymer called polyvinylpyrrolidone.

The team has shown that polyvinylpyrrolidone, a long chain insulating polymer, could form hydrogen bonds with ions in the cells and also prevent moisture in the air from invading perovskite materials. The hydrogen-bonding-initiated self-healing repairs the decayed perovskite solar cell back to the original state, continue to work, and alleviate long-term cell instability.

Greatcell Solar announces bankruptcy

The Directors of Greatcell Solar have sadly announced that a decision was taken to appoint administrators to the Greatcell Solar group of companies following sustained, but ultimately unsuccessful, attempts to secure re-financing for its activities.

Greatcell Solar Limited, Greatcell Solar Industries and Greatcell Solar Australia were placed into voluntary administration. The decision follows a series of unfortunate and unwelcome developments in recent weeks, including the untimely death of Chief Scientist, Dr Hans Desilvestro in a mountaineering accident on 10 November.

EU establishes the MAESTRO project - a €4 million program for perovskite solar materials research

The European Commission has established a new research training network, led by the University of Bath, to make perovskites "truly exploitable" and make perovskite-based devices commercially viable. The new program, called MAESTRO, has been given €4 million in funding and has begun hiring researchers to gain new knowledge and provide innovation in the exploitation of perovskite materials.

A trans-European project, MAESTRO is an inter-sectoral and multidisciplinary network of 10 academic and seven industrial partners from nine EU and EU-Associated countries: the UK, Italy, Spain, Greece, Germany, Poland, Lithuania, Israel and Switzerland.

Greatcell Solar awarded €500,000 in EU Horizon 2020 project

Greatcell Solar has been awarded €500,000 in a European Union Horizon 2020 project known as H2020-SGA-FET-GRAPHENE. The grant to Greatcell's application has occurred through its 100% Italian subsidiary, Greatcell Solar Italy, located in Rome.

The H2020 project is for the innovative development and the installation of a Perovskite Solar Cell (PSC) 10m2 array in the Greek island of Crete and aligns closely with Greatcell's existing technology development plan. Much of the work involved will investigate advanced technology for higher efficiencies, longer life and improved encapsulation of PSC enabled glass substrates, investigating in particular the usage of Graphene in PSC solar cells.
