16% efficiency all-polymer organic solar cells enabled by a finely tuned morphology via the design of ternary blend

Tao Liu et al.

Summary: The performance of all-polymer organic solar cells has been improved by introducing a small amount of BN-T, resulting in increased crystallinity and enhanced exciton harvesting and charge transport. This enhancement is attributed to the reduced nonradiative energy loss and improved energy and charge transfer between acceptors, making AP-OSCs potentially as efficient as devices based on small molecule acceptors.

Rational Anode Engineering Enables Progresses for Different Types of Organic Solar Cells

Ruijie Ma et al.

Summary: Anode modification is crucial for enhancing the performance of organic solar cells (OSCs), with various doped hole transport layers (HTLs) showing improved work functions and conductivities. The study demonstrates that different adulterants formed varying hydrogen bonds in HTLs, resulting in different interfacial morphology and mobility, affecting recombination differently. The doping strategy extends to a high-performance system, achieving a significant efficiency increase in all-polymer solar cells.
