چکیده

A light absorbing pi-conjugated oligomer-tetrafullerene nanoarray has been synthesized and its photophysical study reveals the presence of an intramolecular energy transfer. A phototovoltaic device fabricated from this nanoarray and poly(3-hexylthiophene) shows an external quantum efficiency of 15% at 500 nm.

Towards stable silicon nanoarray hybrid solar cells

Silicon nanoarray hybrid solar cells benefit from the ease of fabrication and the cost-effectiveness of the hybrid structure, and represent a new research focus towards the utilization of solar energy. However, hybrid solar cells composed of both inorganic and organic components suffer from the notorious stability issue, which has to be tackled before the hybrid solar cells could become a viabl...

Investigation of Indigo/thioindigo Tandem Dye-Sensitized Solar Cells

In this paper we used two free-metal organic dyes (dye 1 and dye 2) based on indigo and thioindigo with cyanoacrylic acid as the electron acceptor group. The proposed dyes were sensitized from naphalene as the starting material by standard reactions and characterized by different analytical techniques and UV-Visible spectroscopy after purification. Spectrophotometric measurements of the organic...

Improvement of light harvesting by inserting an optical spacer (ZnO) in polymer bulk heterojunction solar cells: A theoretical and experimental study

By introducing a thin ZnO layer as an optical spacer, we have demonstrated that inserting this layer between an active layer and a reflective electrode results in a re-distribution of the optical electric field inside bulk heterojunction solar cells. A theoretical analysis by optical modeling showed that the thin ZnO layer could shift the position of the maximum of the electric field into the a...

Enhanced optical absorption in organic solar cells using metal nano particles

In this study, for increasing absorption of the active layer in bulk hetero junction (BHJ) organic solar cells (OSCs) we used surface Plasmon effects of metal nano particles (MNPs). We embedded the MNPs inside the active layer and studied the device structure. For shown the results we investigated the model of our structure with Finite Difference Time Domain (FDTD) numerical method and achieved...
