Solar Technology & PV R&D News

A new type of product for solar cells was proposed by specialists of the Ural Federal University (UrFU) as well as the Institute of Organic Synthesis of the Ural Branch of the Russian Academy of Sciences together with their associates. The compounds found will considerably decrease the cost of solar cell production. The article was released in the New Journal of Chemistry.

In the unique experiment, Panasonic located that battery storages, pure hydrogen fuel cell generators as well as solar PV generators can be made to work together for a stable supply of power and also appropriate control in a building or facility. Panasonic held that the solution is unaffected by climate adjustment.

By utilizing geothermal cooling, a research group from the University of Alcala in Spain has actually established a prototype solar panel with approximately 14% greater performance.

A team of scientists has found a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. This new mechanism, which does not depend upon the typical kinetic technique, has the potential to considerably enhance the energy density-- the amount of energy stored relative to the weight or volume-- of batteries.

Mesoscopic dye-sensitized solar cells (DSCs) were designed in 1990s by Brian O'Regan and Michael Grätzel, taking on the latter's name-- the world-famous Grätzel cells. DSCs convert light into electrical power via photosensitizers-- dye compounds that absorb light and inject electrons into an array of oxide nanocrystals which ultimately are collected as electrical current.

Just Recently, Junyou Yang and Yubo Luo from the Huazhong University of Science as well as Technology, in cooperation with Xin Li from the National University of Singapore, released an article labelled "Enhancing the stability of planar perovskite solar cells by green as well as affordable cellulose acetate butyrate" in Journal of Energy Chemistry.

A research group, affiliated with UNIST has prospered in achieving a power conversion efficiency (PEC) of 23.50% in a perovskite-silicon tandem solar cell built with a special textured anti-reflective coating (ARC) polymeric film. According to the research study group, the PCE of the tool with the ARC film was sustained for 120 hrs, keeping 91% of its initial value.

Kesterite (Cu2ZnSnS4, CZTS) is a sulfide mineral with an one-of-a-kind lattice structure that can be taken into consideration as derived from chalcopyrite CuInSe2 (CIS) by substituting two atoms of In3+ in the chalcopyrite by one atom of Zn2+ and also one atom of Sn4+.

Heterojunction Solar cells combine two various technologies into one cell-- a crystalline silicon cell sandwiched in between 2 layers of amorphous "thin-film" silicon

A research team, led by Professor Hyesung Park in the Department of Materials Science and Engineering at UNIST has done well in producing possibly high efficiency, stable, as well as scalable perovskite solar cells (PSCs) using vacuum deposition device, a technique of fabricating organic light-emitting display tools (OLEDs). Such technique is additionally helpful for the automation of batteries, which is anticipated to additional increase the commercialization of the PSCs, according to the research team.

A research study team led by Prof. Ye Jichun at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has established high-performance monolithic perovskite/black silicon (b-Si) solar cells with a tunnel oxide passivated call (TOPCon), achieving a certified power conversion efficiency (PCE) of 28.2%. Results were published in Joule.

Due to their extremely high efficiency in transferring electrical costs from light, perovskites are called the future generation material for photovoltaic panels and also LED screens. A team led by Dr. Lei Su at Queen Mary University of London now have designed a brand-new application of perovskites as fiber optics. The results are published in Science Advances.

Metal halide perovskite solar cells have actually drawn in substantial focus as their power conversion performances (PCEs) remained to increase from below 4% to over 25%.

Establishing low-cost and steady steel electrodes is vital for automation of perovskite solar cells (PSCs). As an earth-abundant component, Cu comes to be a different candidate to change rare-earth element electrodes such as Au and Ag, because of its comparable physiochemical residential or commercial properties with simultaneously great security and also affordable.

Empa scientists have, once again, enhanced the efficiency of CIGS flexible solar cells. Separately certified measurements disclosed a power conversion performance of 22.2% to transform light into electrical energy, a renovation from their previous record value of 21.4%.
