Fabrication and characterization of inorganic-organic hybrid solar cells based on CuInS2

Abstract

Chalcopyrite compounds/fullerene solar cells based on copper-indium-disulphide and C60 were produced. Two-types of devices with heterojunction and bulk heterojunction structures were examined and characterized. The bulk heterojunction structure provided better efficiency compared to that of the heterojunction structure. Nanostructures of the solar cells were confirmed as mixed nanocrystals by transmission electron microscopy. A photovoltaic mechanism of the present solar cells was discussed on the basis of the experimental results.

Recent progress in organic–inorganic hybrid solar cells

“…163 An OIH solar cell based on a blend of CuInS 2 and C 60 exhibited a PCE of 0.0008%. 164 CuInS 2 QDs with sizes of 2-4 nm have been successfully synthesized by a facile solvothermal approach with 4-bromothiophenol as the reduction and capping agent. The OIH solar cells based on the MEH-PPV-CuInS 2 QDs blends with a wide spectral response extending from 300 to 900 nm had a PCE of 0.128% at 470 nm.…”

Fabrication and Characterization of CuO-based Solar Cells

“…The purpose of the present work is to fabricate and characterize solar cells with CuO/C 60 structures. Fullerene (C 60 ) is a good electron acceptor, and has been used as the n-type semiconductor active layer for organic cells (Jeong et al, 2007;Takeda et al, 2009).…”

Fabrication and Characterization of Copper System Compound Semiconductor Solar Cells

“…From the FWHM of the −111 peak, the crystallite size of CuO was determined Figure 9. Previously reported values were used for the energy levels [20,30,31]. Compared to the Si semiconductor with an indirect transition band structure, CuO with a direct transition bandgap is more suitable for the optical absorption property.…”

“…Fullerene (C 60 ) is a good acceptor material for solar cells, and has been used as n-type semiconductor active layer for organic thin film solar cells [12,20]. A low-cost method is essential for mass production of CuO-based solar cells, and spin coating is a more economical method compared to vacuum evaporation [6,7].…”
