AbstractTandem organic solar cells are based on the device structure monolithically connecting two solar cells to broaden overall absorption spectrum and utilize the photon energy more efficiently. Herein, we demonstrate a simple strategy of inserting a double bond between the central core and end groups of the small molecule acceptor Y6 to extend its conjugation length and absorption range. As a result, a new narrow bandgap acceptor BTPV-4F was synthesized with an optical bandgap of 1.21 eV. The single-junction devices based on BTPV-4F as acceptor achieved a power conversion efficiency of over 13.4% with a high short-circuit current density of 28.9 mA cm−2. With adopting BTPV-4F as the rear cell acceptor material, the resulting tandem devices reached a high power conversion efficiency of over 16.4% with good photostability. The results indicate that BTPV-4F is an efficient infrared-absorbing narrow bandgap acceptor and has great potential to be applied into tandem organic solar cells.

Hybrid solar cells based on blends of a conjugated polymer, poly-3(hexylthiophene) (P3HT), and silicon nanocrystals (Si NCs) have been developed and characterized. The properties of composite Si NCs/P3HT films which were spun from 1, 2-dichlorobenzene were studied. Under A.M. 1.5 direct illumination conditions (100mW/cm2), devices made with 50wt% 3–5nm Si NCs showed 1.33% power conversion efficiency (PCE) and had a 30% incident-photon-to-current conversion efficiency at 470 nm.

A new narrow bandgap polymer acceptor (PN1) based on a fused-ring small molecule acceptor as the core building block was designed and developed. The optimal all-polymer solar cell based on the blend of PM6 and PN1 achieved an outstanding power conversion efficiency of 10.5% with a high open-circuit voltage of 1.0 V, a short circuit current density of 15.2 mA cm−2 and a fill factor of 0.69.
