Solar cells generate renewable energy by converting sunlight into electricity based on the photovoltaic effects. Different types of solar have been developed with employment versatile organic, inorganic, and hybrid semiconductors as photoactive layer among which perovskite evidenced enormous progress in recent years. The maximum achievable power conversion efficiencies organic now surpassed 25% 18%, respectively. Nevertheless, relatively narrow light absorption region large open-circuit voltage loss hinder their further improvements. Recently, an emerging type device, integrated perovskite/organic cell, incorporating perovskites near-infrared semiconductors, has obtained enhanced short-circuit current density while reserving high devices.

Nonhalogenated polymers have great potential in the commercialization of organic photovoltaic (OPV) cells due to their advantage low-cost preparation. However, non-halogenated usually high highest occupied molecular orbital (HOMO) energy levels and inferior self-aggregation properties solution, thus resulting low power conversion efficiencies (PCEs). Herein, two nonhalogenated polymers, PB1 PB2, are prepared. When used fabricate OPV with BTP-eC9, PB1-based device only gives a PCE 5.3%, while PB2-based shows an outstanding 17.7%. After introduction PBDB-TF as third component, PB2:PBDB-TF:BTP-eC9-based optimal weight ratio 0.5:0.5:1 achieves up 18.4%. More importantly, PB2 exhibits good compatibility various nonfullerene acceptors achieve better PCEs than those classical polymer (PBDB-T PBDB-TF)-based devices. is combined wide-bandgap electron acceptor (F-BTA3), this excellent 27.1% 24.6% for 1 10 cm2 devices, respectively, under light intensity 1000 lux light-emitting diode illumination. These results provide new insight rational design novel donors further development materials broadening application cells.

Efficiencies of organic solar cells have practically doubled since the development non-fullerene acceptors (NFAs). However, generic chemical design rules for donor-NFA combinations are still needed. Such proposed by analyzing inhomogeneous electrostatic fields at donor-acceptor interface. It is shown that an acceptor-donor-acceptor molecular architecture, and alignment parallel to interface, results in energy level bending destabilizes charge transfer state, thus promoting its dissociation into free charges. By a series PCE10:NFA cells, with NFAs including Y6, IEICO, ITIC, as well their halogenated derivatives, it suggested quadrupole moment ca 75 Debye A balances losses open circuit voltage gains generation efficiency.

Abstract Organic solar cells benefit from non‐fullerene acceptors (NFA) due to their high absorption coefficients, tunable frontier energy levels, and optical gaps, as well relatively luminescence quantum efficiencies compared fullerenes. Those merits result in yields of charge generation at a low or negligible energetic offset the donor/NFA heterojunction, with over 19% achieved for single‐junction devices. Pushing this value significantly 20% requires an increase open‐circuit voltage, which is currently still below thermodynamic limit. This can only be by reducing non‐radiative recombination, hereby increasing electroluminescence efficiency photo‐active layer. Here, current understanding origin decay, accurate quantification associated voltage losses are summarized. Promising strategies suppressing these highlighted, focus on new material design, optimization donor–acceptor combination, blend morphology. review aims guiding researchers quest find future harvesting blends, combine yield exciton dissociation radiative free carrier recombination losses, closing gap inorganic perovskite photovoltaics.
