Chemists at Kaunas University of Technology (KTU) in Lithuania have developed materials that can enhance solar panels for indoor use. These photovoltaic cells are able to generate electricity even in low-light conditions, offering a solution to the issue of energy wastage from indoor light sources. This innovation provides a clear market niche for efficient indoor photovoltaic cells, especially with the rapid growth of IoT technologies. The synthesis of new hole-transporting derivatives by Dr. Asta Dabulienė has significantly improved the efficiency of indoor perovskite photovoltaic cells, paving the way for wider applications in electronic devices.
As the consumption of oil and gas continues to contribute to global climate change, there is a growing need for renewable and environmentally friendly energy sources such as wind, water, and solar power. Solar energy stands out as a flexible, efficient, and cost-effective option, making it a promising solution to combat the climate crisis. By harnessing indoor photovoltaics, electricity can be generated even in low-intensity light conditions, providing a sustainable alternative to traditional energy sources. This research addresses the challenge of utilizing light sources indoors and through windows, which is currently wasted on a daily basis.
The development of indoor photovoltaic cells presents a valuable opportunity for integration into electronic devices such as mobile phones and pocket flashlights. These cells can generate electricity under artificial light, offering a sustainable solution to optimize energy consumption in IoT applications. Dr. Dabulienė’s work on synthesizing efficient hole-transporting derivatives for indoor perovskite photovoltaic cells has led to improved charge transport efficiency and reduced recombination losses, ultimately enhancing overall cell performance. The research also highlights the potential of thiazol[5,4-d]thiazole derivatives in increasing the efficiency of perovskite solar cells for indoor use.
The collaboration between international teams of scientists has played a crucial role in developing innovative solutions for indoor solar cells. Researchers from KTU, Ming Chi University of Technology in Taiwan, and King Abdullah University of Science and Technology in Saudi Arabia have collectively contributed to the synthesis, theoretical studies, and construction of perovskite solar cells. This collaborative effort has led to significant advancements in the efficiency and performance of indoor photovoltaic cells, showcasing the importance of international cooperation in driving scientific innovation. The success of this project has also opened up opportunities for future collaborations and research projects within the European Horizon Programme.
