Organic solar cells (OSCs) represent one of the most important emerging photovoltaic technologies that can implement solar energy conversion efficiently. The chemical structure of organic semiconductors deployed in the active layer of OSCs plays a critical role in the photovoltaic performance and chemical/physical stability of relevant devices.

Compared with inorganic solar cells, the bandgap tunability of organic semiconductors provides great superiority for the application of indoor OSCs. However, indoor OSCs are still in their infancy and the development greatly lags behind the outdoor counterparts with regard to the design of molecule and device structure.

Organic solar cells (OSCs) have been recognized to have tremendous potential as alternatives to their inorganic counterparts, with devices that are low-cost, lightweight, and easily processed and have less environmental impact.
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.
