We numerically investigate the light absorption enhancement of organic photovoltaic cells by embedding Ag nanoparticles and nanochains within the active layer using a finite element method. We analyze the enhancement mechanism of light absorption and systematically study the influence of factors such as the size and the period of silver nanoparticles. The result shows the localized surface plasmon resonance of the particles has a significant influence on the light absorption. Under AM1.5 illumination condition, a relative enhancement with a factor of 107.1% is observed for nanoparticles with a diameter of 30 nm and a period of 200 nm. In addition, different types of nanochain structures have been studied, and we find that, comparing to monodisperse nanoparticles, nanochain structures can further enhance the light absorption because of the stronger light harvesting in the long wavelength range of 600–800 nm.

Enhancement of light absorption in solar cell presents a strong challenge to its overall performance. We analyzed an Organic Solar Cell (OSC) with Photonic Crystal (PC) structure using Finite Difference Time Domain (FDTD) method. Aluminum oxide (Al2O3) has been used as photonic crystal structure and the lattice structure has been chosen to be hexagonal. Absorption enhancement has been observed by changing the height of the Hexagonal Lattice structure (HLS). When height is increased to 0.26 and radius to period ratio (r/a ratio) is set to 0.4, there is a significant increase of absorption in the middle wavelength region approximately from 463 nm to 575 nm and a significant decrease in lower wavelength. As the height is increased further, these changes in absorption begins to increase and at a certain value, these changes begin to reverse. Almost same phenomena occur when r/a ratio is 0.2 and 0.3 taken at approximately same height.Journal of Bangladesh Academy of Sciences, Vol. 42, No. 1, 87-97, 2018

The Way

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]fluorene which can be synthesized via mildly air-sensitive techniques and the end products handled readily under atmosphereic conditions. Through transmetallation via diarylzinc reagents a series of derivatives were sythesized which show broad absorption profiles that highlight the versatility of this backbone to be used in organic solar cell devices. These compounds can be synthesized in large yields, in alow number of steps and functionalized at many stages along the way providing a large depth of possibilities. Exploratory device paramaters were studied and show PCE of 2%.
