A novel strategy employs 2D materials to construct cascaded band alignment, enabling efficient charge transport and reducing energy loss. An innovative approach utilizes donor–acceptor blends; active layer morphology and interfacial engineering minimize charge recombination to enable high performance and long-term device stability. This review uniquely consolidates the roles of 2D materials as electron transport layers and hole transport layers across three major classes of solar cells: perovskite, organic and dye-sensitized solar cells.

An innovative approach utilizes donor–acceptor blends; active layer morphology and interfacial engineering minimize charge recombination to enable high performance and long-term device stability. This review uniquely consolidates the roles of 2D materials as electron transport layers and hole transport layers across three major classes of solar cells: perovskite, organic and dye-sensitized solar cells. The growing global energy demand and worsening climate change highlight the urgent need for clean, efficient and sustainable energy solutions. Among emerging technologies, atomically thin two-dimensional (2D) materials offer unique advantages in photovoltaics due to their tunable optoelectronic properties, high surface area and efficient charge transport capabilities.
