EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

As the world moves to a more sustainable economy, renewable energy sources will have an increasing role in electricity generation. Converting sunlight into electric current is one of the most promising technologies in this area. Silicon solar cells dominate the photovoltaic device landscape, but there exist possible improvements that only organic materials could offer, being cheap,...

The conference studies the development of Na and K doped ZnO thin films prepared by easy low-cost spray pyrolysis method for photovoltaic thin films solar cells. The resulting coatings crystallize in a single hexagonal phase of wurtzite structure with preferred c-axis orientation along (002) crystal plane. Dense, well attached to the substrate, homogeneous and highly transparent layers were...

Thin-film photovoltaic (PV) technologies, and Cu(In,Ga)Se2 (CIGS) thin-film solar cells in particular, have been the subject of increasingly rigorous study of late. There are several motivating factors for the development of thin-film photovoltaics, such as reduction in raw material usage, decrease in cell weight, and the possibility of deposition on flexible substrates. Furthermore,...

А successful tactic for contravention of the theoretical limit on the solar cells efficiency is the implementation of photoactive materials prone to singlet fission (SF)[1]. The first documented singlet fission material – anthracene, was accredited in 1963 but it turned relatively inefficient due to the small size of its conjugated system. About half a century later, it was shown that...

A decade ago, it was shown that the organic photovoltaics have the potential to be highly efficient due to a process known as singlet fission (SF). Hence, the identifying of SF chromophores is a key stage in the development of a new generation of solar cells.
A number of studies demonstrate that the SF propensity is strongly dependent on the molecular structure and the supramolecular...

Photovoltaic solar energy is a clean, abundant, and highly promising green energy source, tackling CO2 generation and climate change. Light concentration can improve solar cell efficiency and reduce raw materials consumption by focusing the light in a much smaller cell. This study aims to develop and produce a micro-lens array to increase the efficiency of micro-concentrator solar cells by...

The number of scientific communications commenting on the unique properties and the high potential for various applications of the compounds with diradical character grows constantly. It was demonstrated that molecules with low-to-intermediate diradical character are amidst the few prospective candidates for singlet fission chromophores [1], hence, are promising highly efficient photovoltaics....
