چکیده
Kesterite Cu2ZnSn(SxSe1−x)4 has tunable band-gap values in the range 1 to 1.5 eV depending upon Sulphur/Selenium stoichiometry. We analyze proposed tandem configuration of kesterite absorber family using SCAPS-1D for device performance. Pure sulphide Cu2ZnSnS4 (CZTS) bandgap is utilized as top cell and a sulpho-selenide (CZTSSe) 1.1 bottom stacked configuration. utilize script file capability SCAPS simulate effect presence on cell; incident spectrum passes though cell, portion filtered out before it reaches cell. The condition identical short circuit current (JSC) two cells attained by optimization. observe that conservative estimate two-junction CZTS could achieve minimum efficiency 15%. This study brings thin film CZTS/CZTSSe multi-junction enhancing earth abundant based solar cells.

Plasmonic polymer tandem solar cell.
We demonstrated plasmonic effects in an inverted tandem polymer solar cell configuration by blending Au nanoparticles (NPs) into the interconnecting layer (ICL) that connects two subcells. Experimental results showed this plasmonic enhanced ICL improves both the top and bottom subcells' efficiency simultaneously by enhancing optical absorption. The presence of Au NPs did not cause electrical ch...
متن کاملHigh performance polymer tandem solar cell
A power conversion efficiency of 9.02% is obtained for a fully solution-processed polymer tandem solar cell, based on the diketopyrrolopyrrole unit polymer as a low bandgap photoactive material in the rear subcell, in conjunction with a new robust interconnecting layer. This interconnecting layer is optically transparent, electrically conductive, and physically strong, thus, the charges can be ...

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...
متن کاملDye-sensitized CuAlO2 photocathodes for tandem solar cell applications
Dye-sensitized solar cells (DSCs) using the p-type semiconductor CuAlO2, in conjunction with a highly effective hole injecting dye and an iodide-triiodide-based electrolyte have been produced, demonstrating photocathodic behavior. An improved open-circuit voltage (VOC) of 333 mV was observed, compared to analogous devices using NiO, which can be explained by the CuAlO2 valence-band energy, whic...
متن کاملA polymer tandem solar cell with 10.6% power conversion efficiency
An effective way to improve polymer solar cell efficiency is to use a tandem structure, as a broader part of the spectrum of solar radiation is used and the thermalization loss of photon energy is minimized. In the past, the lack of high-performance low-bandgap polymers was the major limiting factor for achieving high-performance tandem solar cell. Here we report the development of a high-perfo...
