Organic solar cells (OSCs) that converted sunlight into electricity have obtained numerous progress in the past two decades. With the efforts of developing new conjugated materials, the power conversion efficiencies (PCEs) of OSCs have realized over 18%, which are comparable with other types of solar cells.
One of the most successful small molecule materials for organic solar cells is PCDTBT, or poly [N-9’-heptadecanyl-2,7-carbazole-alt-5,5- (4’,7’-di-2-thienyl-2’,1’,3’-benzothiadiazole)]. PCDTBT has a high molar extinction coefficient, which enables it to absorb a large amount of light in the visible spectrum.
While organic solar cells have shown promise in recent years as a low-cost and flexible alternative to traditional silicon-based solar cells, there are still several challenges that need to be addressed in order to improve their efficiency, stability, and scalability.
Here are some potential future developments and trends for organic solar cells : 1. Tandem cells: Tandem solar cells, which combine multiple layers of different materials to capture a wider range of the solar spectrum, have shown great promise in improving the efficiency of organic solar cells.
Effective molecular design strategies for each type of OSC are discussed and promising research directions highlighted, particularly those relevant to facilitating the industrial manufacturing of OSCs. Advances in photoactive-layer materials have contributed to the increase in the performance of organic solar cells.
Small molecules have also been investigated as potential materials for organic solar cells. Compared to polymers, small molecules have a well-defined structure and higher purity, which can improve the reproducibility and efficiency of the solar cells.
Improving the reproducibility of organic solar cells will require standardization of materials, device architectures, and testing methods. Addressing these challenges will require a multidisciplinary approach that brings together expertise in materials science, chemistry, physics, and engineering.
