The article discusses the development of innovative BHJ IPV-Anodes for cost-effective solar hydrogen production. It highlights the potential of organic semiconductors for driving photoelectrochemical (PEC) reactions efficiently. The focus is on addressing challenges like high performance, stability, low cost, and use of earth-abundant materials in PEC systems. The research introduces BHJ IPV-Anodes that utilize self-adhesive graphite sheets functionalized with an earth-abundant nickel-iron oxyhydroxide electrocatalyst to enhance efficiency and stability. These IPV-Anodes demonstrate high photocurrent densities over 25 mA cm−2 and days-long operational stability, with monolithic organic tandem IPV-Anodes achieving bias-free solar water splitting with 5% STH efficiency. The study emphasizes the fabrication process of the organic IPV-Anodes, including the use of specific materials like PM6, D18, and L8-BO in the ternary blend. By incorporating cost-effective materials and manufacturing methods, such as self-adhesive graphite sheets and earth-abundant electrocatalysts, the research aims to make hydrogen production more affordable and eco-friendly. Overall, the research presents a significant advancement in solar-to-fuel conversion, offering a promising solution for sustainable and low-cost hydrogen production in the future.
