Maximum efficiency of oxygen-deficient solar power generation

Do organic solar cells improve power conversion efficiency?

Because of the vigorous design and development of organic photovoltaic materials, power conversion efficiency (PCE) is improved rapidly, approaching the threshold of 20%. However, the high costs and intrinsic operational instability of organic solar cells (OSCs) have slowed down its commercialization.

Does organic photovoltaic technology have low power conversion efficiency?

Nature Reviews Electrical Engineering 1, 581–596 (2024) Cite this article Organic photovoltaic (OPV) technology is flexible, lightweight, semitransparent and ecofriendly, but it has historically suffered from low power conversion efficiency (PCE).

What are the limitations of first generation solar cells?

First generation solar cells have some limitations, such as a relatively low efficiency and a high cost of raw materials. Their efficiency drops significantly in high temperatures, which can cause power loss. Recent research has been focused on developing new materials and technologies to improve the efficiency and to reduce the cost of production.

What is the efficiency of a single-junction organic solar cell?

Yuan, J. et al. Single-junction organic solar cell with over 15% efficiency using fused-ring acceptor with electron-deficient core. Joule 3, 1140–1151 (2019). Cui, Y. et al. Over 16% efficiency organic photovoltaic cells enabled by a chlorinated acceptor with increased open-circuit voltages. Nat. Commun. 10, 2515 (2019).

What is the power conversion efficiencies of organic photovoltaic (OPV) devices?

Thanks to the development of novel electron acceptor materials, the power conversion efficiencies (PCE) of organic photovoltaic (OPV) devices are now approaching 20%. Further improvement of PCE is complicated by the need for a driving force to split strongly bound excitons into free charges, causing voltage losses.

Which non-fullerene organic solar cells have the highest efficiency?

Slot-die printed non-fullerene organic solar cells with the highest efficiency of 12.9% for low-cost PV-driven water splitting. High-efficiency nonfullerene organic solar cells enabled by 1000 nm thick active layers with a low trap-state density. ACS Appl. Mater. Interfaces. 2020; 12: 18777-18784
