Organic solar cells (OSC) based on organic semiconductor materials that convert solar energy into electric energy have been constantly developing at present, and also an effective way to solve the energy crisis and reduce carbon emissions. In the past several decades, efforts have been made to improve the power conversion efficiency (PCE) of OSCs. During this period, a variety of structural and material forms of OSCs have evolved. Commercializing OSCs, extending their service life and exploring their future development are promising but challenging. In this review, we first briefly introduce the development of OSCs and then summarize and analyze the working principle, performance parameters, and structural features of OSCs. Finally, we highlight some breakthrough related to OSCs in detail.

“…The performance of solar cells is affected by the nanostructure designs that have been used, such as nano-holes [ 15 , 16 ], nanorods [ 17 ], nanopyramids [ 18 ], and nanowires [ 19 ]. Furthermore, previous research found that localized surface plasmons (LSPs) are sensitive to the type of material, such as silver [ 20 , 21 ], gold [ 6 , 22 ], indium [ 23 ], and aluminum [ 7 ]. In addition, localized and propagating surface plasmons are highly affected by the size [ 7 ], periodicity [ 7 ], and shape [ 24 ] of the nanostructure.…”

In this work, we present and explore the characteristics of a plasmonic metamaterial absorber based on a metal–insulator–metal functional stack. The proposed structure consists of glass “sandwiched” between a silver reflector and a titanium metallic disc, embedded inside a Ti periodic nano-hole array, as an outside layer. In the visible and infrared regimes, the optical absorption spectra of such structures have been investigated using the finite difference time domain method. The impact of modifying nano-hole and embedded disc diameters on the absorber’s performance has been investigated. Changing these two distinct structural parameters tunes the coupling effect between the localized and propagating surface plasmons. The adequate bandwidth, average spectral absorption rate, and short circuit current density are calculated to determine the performance of the designated absorber. The proposed structure of the plasmonic metamaterial absorber reaches an average absorption of over 94% in a bandwidth of 0.81 µm and near-perfect absorption of 98% around the wavelength of 0.7 µm, with an almost 100% relative absorption bandwidth and 41 mA/cm2 short circuit current density. In addition, the results show that the disc-in-hole absorber’s structural parameters can be changed precisely and facilely to tailor to the absorption spectra.

“…29 Heidarzadeh et al found that coupling Ag− Au core−shell NPs in a double or triple arrangement can significantly improve the properties of perovskite solar cells. 30 The strong coupling between excitons of semiconductors and plasmons of noble metals can result in new polaritonic modes (plexcitons), which can not only significantly promote the efficiency of interfacial charge transfer but also greatly enhance the absorption intensity of interfacial charge-transfer excitons. 31 In this paper, we provide detailed investigation on the optical absorption and electron−hole coherence in polythiophene (PT) and indene-C60 bisadduct (IC 60 BA) as a donor and an acceptor, respectively, as well as the PT:IC 60 BA and NP dimer system, and report our strategy on plasmon-enhanced OSCs, including significantly enhanced strong optical absorption, and strongly enhanced intermolecular or intramolecular charge transfer by LSPR.…”

Physical Mechanisms on Plasmon-Enhanced Organic Solar Cells

2021

An organic solar cell is regarded as one of the emerging and potential alternatives for solar cells, due to its low cost and high photoelectric conversion efficiency. Here, using the plasmon-enhanced method, the electric field of the polythiophene/indene-C60 bisadduct (PT:IC60BA) donor–acceptor system as the photoactive molecular layer is significantly enhanced up to the order of 104 at around 475 nm. Besides, the surface plasmon thermal effect is calculated based on the coupling model of a nanoparticle dimer with a Ag film, where the molecular layer is in the nanocavity between the dimer and the film. The band gap and open-circuit voltage decrease with the increase of temperature. The electron–hole generation rate is enhanced up to 1.4 × 103, and photocurrent can be enhanced around 230 times by surface plasmon resonance. Our results provide theoretical support for plasmon-enhanced organic solar cells.
