Co-sensitization cocktail with methylfuran dyes catapults photovoltaic performance: Nearly 50% boost over standard N719
Abstract
This groundbreaking study reveals an unparalleled strategy for significantly enhancing the efficiency of dye-sensitized solar cells by co-sensitizing a pioneering combination of organometallic dyes. By employing two ingeniously engineered co-sensitizers, MO-1 and MO-2, in tandem with the standard N719 dye, our revolutionary device demonstrated remarkable performance improvements. The power conversion efficiency increased by nearly 50% compared to N719 alone, reaching an exceptional value of 10.96%. MO-2 played a key role in boosting the outputs by expanding the light harvesting and current generation capabilities. Additionally, the unique alignment and geometry of our rationally designed co-sensitizers, optimized using density functional theory, significantly contributed to remarkable efficiency gains. By effectively reducing electron-hole recombination and suppressing dye aggregation, our sensational cocktail co-sensitization approach opens new avenues for photovoltaic utilization. This pioneering dual-dye method paves the way for a new era of next-generation solar energy.
