Investigation of Thermal Instability of Additive-Based High-Efficiency Organic Photovoltaics

open access: yesInternational Journal of Photoenergy, 2014
Most photovoltaics operate at high temperature under sunlight. In this work, the thermal instability of diiodooctane-based high-efficiency bulk heterojunction (BHJ) organic photovoltaics (OPVs) is studied.

Importance of structural hinderance in performance–stability equilibrium of organic photovoltaics

open access: yesNature Communications, 2022
The intrinsic trade-off between efficiency and stability is a challenging issue for organic photovoltaics. Here, the authors develop non-fullerene acceptors with tailored side-group hindrance and backbone planarity and realise efficiency of 18.3% and ...

Ultrafast Charge Separation in Low Band-Gap Polymer Blend for Photovoltaics

open access: yesEPJ Web of Conferences, 2013
We track ultrafast charge dissociation in a particularly promising low-band-gap- polymer:fullerene blend for organic photovoltaics. Impulsive photoexcitation with excess energy leads to a 30-fs formation of an hot charge transfer state, precursor of free
