Use of Recovered Carbon Black from Waste Tires in Triple Mesoscopic Stack Perovskite Solar Cells.

ABSTRACT: This research addresses critical challenges in the photovoltaic (PV) industry to achieve net-zero greenhouse gas emissions by 2050, amidst geopolitical semiconductor supply risks and escalating volumes of PV waste. We demonstrate the opportunity to address these challenges through the design of PV cells which are compatible with a circular economy. In this proof-of-concept study, unpurified locally sourced recovered carbon black (rCB) from waste tires was integrated into the mesoporous carbon layer of triple mesoscopic perovskite solar cells as a sustainable alternative to virgin carbon sources, and comparable efficiencies (9.98%) to commercial carbon paste benchmarks (10.4%) were attained. Key findings reveal that the presence of sulfur, silica, and zinc oxide contaminants only affected p
