What is the power conversion efficiency of solution-processed organic photovoltaics (OPV)?

During the last years, the development of new active materials has led to constant improvement in the power conversion efficiency (PCE) of solution-processed organic photovoltaics (OPV) to nowadays record values above 17% on small lab cells.

Are organic photovoltaics suitable for high-speed optical data receivers?

We show that organic photovoltaics (OPVs) are suitable for high-speed optical wireless data receivers that can also harvest power. In addition, these OPVs are of particular interest for indoor applications, as their bandgap is larger than that of silicon, leading to better matching to the spectrum of artificial light.

Can organic photovoltaics be a power source based on cross-linked PEDOT PSS electrodes?

Bihar, E. et al. Fully inkjet-printed, ultrathin and conformable organic photovoltaics as power source based on cross-linked pedot:pss electrodes. Adv. Mater.

Are organic optoelectronic devices semi-transparent?

Therefore, research on ultra-flexible OPVs has accelerated over the past decade 15, 16, 17. In addition to the inherent mechanical softness of organic absorbers, the design and tailoring of molecular structures enable organic optoelectronic devices to be semitransparent (ST).

Are OPV devices a good choice for building- and greenhouse-integrated energy harvesting?

The ST nature of these OPV devices enables their application to facades, rooftops, and windows for building- and greenhouse-integrated energy harvesting. Despite these desirable characteristics, the OPV performance is limited by the tradeoff between PCE and average visible transmittance (AVT).

Does open-circuit voltage increase increase efficiencies in ternary organic photovoltaics?

Zhan, L. et al. Desired open-circuit voltage increase enables efficiencies approaching 19% in symmetric-asymmetric molecule ternary organic photovoltaics. Joule6, 662–675 (2022). Zhu, L. et al. Single-junction organic solar cells with over 19% efficiency enabled by a refined double-fibril network morphology. Nat. Mater.21, 656–663 (2022).
