💡Can you imagine semi-transparent solar cell windows? 🪟
We in the LabTFEnergyMat are working on bringing this futuristic plan to nowadays!

Antimony sulfide (Sb2S3) is a promising absorber material for indoor and semi-transparent photovoltaic devices. However, the high cost and low transmittance of commonly used hole transport materials (HTMs) may impede the advancement of this technology. In our published paper, we investigated three novel, dopant-free fluorene-based enamines (V1275, V1235 and V1461) with different aliphatic chain lengths as HTMs in Sb2S3 based semi-transparent solar cells for the first time.

Effective comes from joint effort!💪

During the first days of November, we had a lovely opportunity to meet with our friends and colleagues from KTU Kauno technologijos universitetas/Kaunas University of Technology (LT), Institute of Solid State Physics University of Latvia (LV) and IFE - Institutt for energiteknikk (NO). The meeting took place in the frame of EEA Iceland Lichtenstein Norway grant project „Development of semi-transparent bifacial thin film solar cells for innovative applications“ at IFE.
Up to date study progress and upcoming prospects were discussed.

Do you remember Arvo Mere and his grandson Armin Mere? 👀

A small recap: Arvo is a mentor for a group of enthusiastic Estonian students, including his grandson, in Solaride e who built a to participate in Australia in Bridgestone World Solar Challenge 2023. And now we know that the race was a complete success! 💪

Solaride achieved 🥉3rd place in cruiser class and received a special award for the best performance in technical inspection!

On September 18-22 our new ERA Chair holder professor Maciej Sibiński and Daria Miliaieva PhD participated in the 40th European Photovoltaic Solar Energy Conference and Exhibition also known as EU PVSEC held in Lisbon.
It is the most important scientific, technical and industry meeting in the field of in Europe. This year, after a break caused by the pandemic, the event gathered an exceptional number of scientists from around the world interested in the development of new solar cell technologies and elements of photovoltaic installations, as well as a huge number of issues related to the simulation, design, and measurement of photovoltaic elements.
An important element of this event was the awarding of the Bequerel Prize to Dr. Gunter Erfurt, president of Meyer Burger , which launched an innovative solar cell line located in Europe, operating without the need to use a clean-room laboratory. 👏

WoW ! Our rainbow-coloured glass is flying high! 🛩

The research carried out by Jekaterina Sydorenko et al on the rainbow-colored glass 🌈 has been published in airBaltic Inflight magazine.
This rainbow glass is capable of neutralising around 200 different toxic substances and kill germs in indoor air.

So, if you plan to fly with airBaltic soon, read the article on board!

Do you remember Alka? 👀

She has been busy in our lab in the frame of ETAG project “Development of inorganic NiOx thin films as hole transport materials for Sb2S3 semi-transparent solar cells” to chemically synthesize NiOx nanoparticle dispersion.
This NiOx nanoparticle dispersion is ready to be incorporated on Sb2S3 semi-transparent solar cells to form an efficient Hole transport material (HTM). These HTM paves path for all-inorganic solar cell by using inorganic hole-transporting material instead of organic counterpart for the design of stable, economic, and efficient semi-transparent Sb2S3 solar cells.

We are happy to introduce our new colleague, Daria Miliaieva!

Daria studied chemistry in Moscow State University, and she defended her titled ‘Assembly and optoelectronic properties of nanodiamond-dye composites ‘ in Czech Technical University in Prague.

Daria participated in Building Bridges meeting 2023 held in Dresden, Germany, which is an example of the fighting with brain drain from the region combining scientific, political, and industrial initiative – a good example to follow not only for Saxony, but whatever land with brain outflow, Estonia included.
Daria: "We discussed with start-ups investors and science-industry-society mediators like FutureSax the detailed steps on how to materialize the research and make it available to public. Three main areas of knowledge were under focus, namely Health, Artificial Intelligence and Energy. We met with Energy sector representatives in recycling of materials like indium at Helmholtz-Zentrum Dresden-Rossendorf and hydrogen fuel cells at Ostwald company (Germany) might become good complementary partners to solar cell research held in Laboratory for Thin Film Energy Materials at .

All the best to Daria!
