 Abstract distributed photovoltaics in living environments harvests the sunlight in different incident angles throughout the day. This requires thinner, more flexible panels than traditional solar panels, making them difficult to install. To address this issue, researchers have developed planar solar cells with large light-receiving angles, reducing the need for installation form factors. Additionally, they have created polymer solar cells with hierarchical features, such as nanosized phase separation and micron-scale optical field trapping structures, which increase their efficiency and light-receiving angle. As a result, these polymer solar cells are well-seated for distributed photovoltaics applications due to their low installation requirements.
