What is the power conversion efficiency of organic photovoltaics (OPV) fabricated in laboratories?

npj Flexible Electronics 6, Article number: 89 (2022) Cite this article The certified power conversion efficiency (PCE) of organic photovoltaics (OPV) fabricated in laboratories has improved dramatically to over 19% owing to the rapid development of narrow-bandgap small-molecule acceptors and wide bandgap polymer donor materials.

Can LbL deposition improve the efficiency and stability of organic solar cells?

We also highlight some key research directions that can help enhance the efficiency and stability of LBL OSCs for their potential applications in the future. Layer-by-layer (LBL) deposition using solution processing is a promising technique for fabricating organic solar cells (OSCs) with high efficiency and stability.

How can hot-blade-coated BHJ films be made flexible OPV based on PBDB-T?

A smoother surface and finer phase separation of the hot-blade-coated BHJ films were observed using atomic force microscopy (AFM). This indicated enhanced stability. Then, hot slot-die deposition was combined with the roll-to-roll process to produce flexible OPV based on PBDB-T:ITIC with a PCE of 8.77%.

How is photovoltaic performance measured?

The photovoltaic performance of all the OSCs was measured in a N 2 -filled glove box at room temperature (ca. 25 Celsius degree) using an Air Mass 1.5 Global (AM 1.5 G) solar simulator (SS-F5-3A, Enlitech) with an irradiation intensity of 100 mWcm −2, which was measured by a calibrated silicon solar cell (SRC2020, Enlitech).

Are solvent-processed organic solar cells suitable for blade-coating?

Zhao, W. et al. Environmentally friendly solvent-processed organic solar cells that are highly efficient and adaptable for the blade-coating method. Adv. Mater.30, 1704837 (2018). Zhang, L. et al. Blade-cast nonfullerene organic solar cells in air with excellent morphology, efficiency, and stability.

Can a Maobi-coated solar module perform pattern-printing?

Maobi can perform complex pattern-printing (such as solar modules) owing to its advantages in writing and painting. The authors realized a fully Maobi-coated solar module containing eight subcells by using this method. The module exhibited a high FF (close to 70%) and Voc of over 6.30 V.
