Scientists at CSIR-NIIST have achieved a new efficiency record of 35.6% in indoor light harvesting using DSCs. This breakthrough technology can replace one-time use primary batteries and reduce environmental pollution. Integration of DSCs into IoT systems offers a sustainable solution by creating self-powered devices. The technology has been published in the Royal Society of Chemistry's Journal of Materials Chemistry A. CSIR-NIIST is translating this technology by developing self-powered prototypes and products to reduce dependence on primary batteries and address climate change.
