Indian Researchers Create 40% Efficient Dye-Sensitized Solar Cell for Indoor Use

A research team from India’s National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) has significantly enhanced the power conversion efficiency and stability of indoor dye-sensitized solar cells (DSCs), achieving a remarkable efficiency of 40% under fluorescent lighting at 4000 lux and 10.40% under standard sunlight conditions. These advancements stem from the innovative use of starburst triphenylamine dye cocktails combined with dual-species copper(II/I) electrolytes, which optimize light absorption and molecular packing for improved performance in low-light environments. The newly developed solar cells demonstrate promising stability, maintaining performance without degradation for over 800 hours in accelerated testing. The team’s work not only presents a sustainable alternative to conventional batteries but also paves the way for practical applications in indoor and outdoor photovoltaics, with ongoing developments focusing on building-integrated solar technologies.
