“…Finally, we should consider that the photovoltaic layer materials in OSC decrease with the introduction of metal nanoparticles, but due to the optical enhancement of nanoparticles, the total amount of light absorbed by OSC as a whole still increases, which not only offsets the loss caused by the reduction of photovoltaic materials, but also further improves [12]. Therefore, metal nanoparticles, especially multi-tip metal nanoparticles, are of great significance to enhance the optical absorption of OSC, and can be used to improve the low photoelectric conversion efficiency of OSC [13].…”

As a new generation of photovoltaic devices, organic polymer solar cell (Organic Solar Cell, OSC) have attracted wide attention of researchers in recent years because of their unique advantages such as simple process, low energy consumption, low cost and large area preparation. However, the development of OSC has encountered bottlenecks: the low carrier mobility of photovoltaic materials forces the thickness of the active layer of OSC to be reduced as much as possible to meet the requirements of effective collection of photogenerated carriers, while the thinner absorption layer will lead to serious optical absorption loss and device performance degradation. Therefore, how to enhance the optical absorptivity of OSC on the premise of effective carrier collection has become a research hot-spot. Based on this characteristic, with the help of finite element method, the structure model of OSC with multi-tip metal nanoparticles is established, and the effects of metal nanospheres and star particles on OSC light absorption factors are studied systematically. Firstly, the effects of introducing metal nanoparticles into different functional layers of OSC (active layer and buffer layer) are compared and analyzed to determine the introduction location of metal nanoparticles in OSC. Secondly, the localized resonance enhancement rules of spherical and cubic metal nanoparticles in the functional layer are discussed. Combined with the theoretical model, the optimal design method of metal nanoparticles structure parameters (size and period) is established. The results show that the absorption enhancement of metal nanoparticles in the active layer of OSC is higher than that in the buffer layer. On the one hand, it can stimulate more electron hole pair separation, improve the separation rate of electron hole pair, on the other hand, it can also make the separated electron hole to obtain more energy, recombination becomes relatively difficult, and the arrival rate of the battery electrode is improved.

“…The advantage of this method is its simplicity and the possibility to obtain results for a wide range of wavelengths in one calculation, as well as the option to set the properties of materials at any point of the calculation grid, which allows considering anisotropic, dispersed and nonlinear media. This method can be accurately applied to general electromagnetic structures, including arbitrarily shaped particles [15][16][17][18][19].…”

To calculate the optical parameters, the finite difference method in the time domain (FDTD) was used, which can be applied to solve Maxwell’s equations. A large number of combinations of a planar structure with metal nanoparticles and a structure with nanowires and metal nanoparticles (NPs) were calculated. The height of nanowires h varied from 50 to 3000 nm, the period of the structure P was 100–600 nm, and the diameter of metal nanoparticles d was 50–400 nm. The reduction of light reflection was determined by the anti-reflection effect of the Si-NWs array itself and the direct scattering effect of metal nanoparticles. It was shown that all structures gave significantly lower reflection coefficients compared to that of a solid silicon plate.

“…Nanostructured semiconductor devices are promising for use in order to increase the efficiency of energy conversion and reduce the cost of materials. In particular, an effective method for increasing light scattering and trapping in solar cells is based on the use of metallic nanoparticles and nanostructure [1][2][3][4][5][6].…”

The optical spectra of structures with Ag nanoparticles between rough and cylindrical nanowires are calculated. The simulation was carried out using the finite-difference time-domain method (FDTD). As a source of radiation, a plane wave with the range of wavelengths 300–1000 nm is used. It is shown that with an increase in the root mean square (RMS) roughness of rough nanowires, the absorption coefficient decreases in the range of 500–750 nm due to an increase in the reflection effect. When silver nanoparticles are added, peaks appear at the wavelength of 840 nm (for cylindrical nanowires) and 900 nm (for rough nanowires), which indicates the manifestation of the surface plasmon resonance effect. It is shown that the electric field strength in a system with rough nanowires is higher than in a system with cylindrical nanowires.
