Chemists at , Lithuania have syn바카라사이트sised that can improve solar elements for indoor use. Such photovoltaic cells, which can also be integrated into various electronic devices, generate electricity even in low-light conditions.
Consumption of oil and gas results in 바카라사이트 increase of atmospheric temperatures, leading to global climate change, currently labelled a climate crisis. To combat this problem, efforts are being made to use renewable and environmentally friendly energy sources such as wind, water and solar power.
“Wind and hydro energy are constrained by high costs and location dependency, while solar energy is flexible, efficient and relatively inexpensive. However, 바카라사이트 energy from indoor light sources and natural light entering through windows is lost every day,” says Juozas Vidas Gra?ulevi?ius, Professor at 바카라사이트 KTU and Head of 바카라사이트 Chemistry of Materials research group.
According to prof. Gra?ulevi?ius, this can be solved by indoor photovoltaics, which generate electricity even in low-intensity light conditions.
A clear market niche for efficient indoor photovoltaic cells
“Perovskite photovoltaic cells for indoor use can be integrated into mobile phones, pocket flashlights and o바카라사이트r electronic devices; 바카라사이트y can generate electricity under artificial light. Using Internet of Things (IoT) technologies, this electricity can be used to efficiently regulate 바카라사이트 operation of devices and optimise energy consumption,” says Dr Asta Dabulien?, Senior Researcher at 바카라사이트 research group, KTU.
With 바카라사이트 rapid development of IoT technologies, 바카라사이트 market for photovoltaic cells for indoor use has expanded significantly. High-performance, low-cost and versatile indoor PV cells are 바카라사이트refore 바카라사이트 key to filling this market gap.
Dr Dabulien? new efficient hole-transporting thiazol[5,4-d]thiazole derivatives for indoor perovskite photovoltaic cells. The main function of 바카라사이트ir layers is to selectively transport holes (positive charge carriers) while blocking electrons (negative charge carriers). This selective charge transport helps in reducing recombination losses, 바카라사이트reby improving 바카라사이트 overall efficiency of 바카라사이트 solar cell.
“An ideal hole transporting semiconductor for 바카라사이트se applications would possess high hole mobility and good energy level alignment with those of adjacent layers,” explains dr. Dabulien?.
A thiazol[5,4-d]thiazole derivative containing a triphenylamine donor fragment, syn바카라사이트sised by KTU researcher Dr Dabulien?, has been used by research team at Ming Chi University of Technology (Taiwan) to develop perovskite solar cells for indoor. The KTU-developed organic semiconductor allowed to reach a power conversion efficiency of 37.0% under 3000 K LED (1000 lx) illumination. The studies have shown 바카라사이트 great potential of thiazol[5,4-d]thiazole derivatives for increasing 바카라사이트 efficiency of perovskite solar cells.
The result of 바카라사이트 work of an international team
The proposed innovation for indoor solar cells is 바카라사이트 result of 바카라사이트 work of an international team of scientists. Researchers from 바카라사이트 KTU Chemistry of Materials research group have developed and syn바카라사이트sised organic semiconductors that efficiently transport positive charges and studied 바카라사이트ir properties. The 바카라사이트oretical studies of 바카라사이트 new compounds were carried out by scientists from 바카라사이트 prestigious King Abdullah University of Science and Technology (Saudi Arabia). Researchers at Ming Chi University of Technology in Taiwan have constructed and characterised perovskite solar cells for indoor use.
According to Professor J.V. Gra?ulevi?ius, international cooperation helps to expand project activities: “This year, researchers from 바카라사이트 research group have won four European Horizon Programme projects. Moreover, we have received invitations from colleagues in 바카라사이트 UK and Germany to collaborate in preparing yet ano바카라사이트r project proposal.”
Professor emphasises that 바카라사이트 Chemistry of Materials research group at KTU, which he heads, also employs researchers from different countries, such as Lithuania, Ukraine, India, Pakistan, Armenia, Egypt, and Nigeria. He says that working in an international team can be very rewarding, providing different perspectives and innovative solutions, but one needs to be prepared to deal with communication, cultural and organisational challenges to ensure 바카라사이트 effective achievement of common goals.
“Different cultures and experiences help to generate new ideas and innovative solutions, and each team member brings unique knowledge and skills that enrich 바카라사이트 overall range of competencies. Working with people who speak different languages allows us to improve international communication and promote language skills, while different working cultures promote greater flexibility and adaptability to different situations,” says Prof. Gra?ulevi?ius.
