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%.

Organic solar cells have potential as an alternative to conventional inorganic solar cell due to low processing cost, flexibility and easy fabrication technique. The goal of this paper is to study the characteristics of the CuPc and PCBM based organic solar cell by introducing a thin layer of Ag at the interface of donor (CuPc) and Acceptor (PCBM), their photovoltaic and optical properties were investigated. The heterojunction solar cells with and without silver inter layer were fabricated through thermal deposition in HR vacuum. The OPV solar cells were characterized using current-voltage graphs, absorbance spectrum and Impedance spectroscopy. Impedance spectroscopy was taken to identify the traps using series resistance, parallel resistance, and Impedance spectrums under different frequencies. Optical behaviors of these devices have been investigated with absorbance spectrum. Introducing Ag to interfacing point produced traps and these traps causes to decreased Voc, Isc, FF, and efficiency. The effect of silver layer at donor acceptor interface was studied.
