A series of (bacterio)chlorophyll derivatives covalently linked with fullerenes were synthesized to explore their potential as donor–acceptor conjugates to organic solar cells (OSCs). Their physical properties and photovoltaic performances were investigated and compared with (bacterio)chlorins without fullerenes. A weak intramolecular interaction between the (bacterio)chlorin chromophore and the fullerene unit(s) was observed in their electronic absorption spectra in solution, and efficient fluorescence quenching occurred in their monomeric states. All the (bacterio)chlorin-fullerene conjugates worked as components for single material OSCs and the best power conversion efficiency of 0.62% with [Formula: see text] mA cm[Formula: see text], [Formula: see text] V, and [Formula: see text] was achieved for chlorin-C3-methyl phenyl-C[Formula: see text]-butylate, DA-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.
