Blue-Coloured Highly Efficient Dye-Sensitized Solar Cells by Implementing the Diketopyrrolopyrrole Chromophore
The paradigm shift in dye sensitized solar cells (DSCs) - towards donor- π bridge-acceptor (D-π-A) dyes - increases the performances of DSCs and challenges established design principles. Framed by this shifting landscape, a series of four diketopyrrolopyrrole (DPP)-based sensitizers utilizing the donor-chromophore-anchor (D-C-A) motif were investigated computationally, spectroscopically, and fa...
متن کاملDiketopyrrolopyrrole derivatives for efficient NiO-based dye-sensitized solar cells.
Two new diketopyrrolopyrrole (DPP) based sensitizers (DPP-Br, DPPCN2) and a novel dyad DPP-NDI (NDI = naphthalene diimide) were synthesized and investigated for use in NiO p-type dye-sensitized solar cells (p-DSCs). The simple push-pull DPP-CN2 gives a promising photoconversion efficiency (PCE) of 0.07% with the iodide/triiodide electrolyte while the PCE of the dyad reaches 0.18% with a cobalt ...
متن کاملA highly efficient organic sensitizer for dye-sensitized solar cells.
We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.
متن کاملHighly efficient photocathodes for dye-sensitized tandem solar cells.
Thin-film dye-sensitized solar cells (DSCs) based on mesoporous semiconductor electrodes are low-cost alternatives to conventional silicon devices. High-efficiency DSCs typically operate as photoanodes (n-DSCs), where photocurrents result from dye-sensitized electron injection into n-type semiconductors. Dye-sensitized photocathodes (p-DSCs) operate in an inverse mode, where dye-excitation is f...
متن کاملHierarchically structured nanotubes for highly efficient dye-sensitized solar cells.
Hierarchical TiO2 nanotube arrays grown on Ti foil are yielded by subjecting electrochemically anodized, vertically oriented TiO2 nanotube arrays to hydrothermal processing. The resulting DSSCs exhibit a significantly enhanced power conversion efficiency of 7.24%, which is a direct consequence of the synergy of higher dye loading, superior light-scattering ability, and fast electron transport.
