Journal ArticleDOI

Modulating dye E(S+/S*) with efficient heterocyclic nitrogen containing acceptors for DSCs.

TL;DR: Acceptor motifs based on nitrogen containing heterocycles have been synthesized for use in dye-sensitized solar cells (DSCs) and the excited-state oxidation potential, E((S+/S*)), may be conveniently tuned with minimal effect on the ground- state oxidation potential of the dye.
Journal ArticleDOI

Stable dye-sensitized solar cells based on organic chromophores and ionic liquid electrolyte

TL;DR: A series of polyene-diphenylaniline based organic dyes (coded as D5, D7, D9 and D11) have been reported for the application in ionic liquid electrolyte based dye-sensitized solar cells as mentioned in this paper.
Journal ArticleDOI

Mesoscopic photosystems for solar light harvesting and conversion: facile and reversible transformation of metal-halide perovskites

TL;DR: This work applies for the first time quartz crystal microbalance (QCMD) measurements in conjunction with X-ray diffraction and scanning electron microscopy to analyse the dynamics of the conversion of PbI(2) to CH( 3)NH(3)PbI (3) by solution processing at room temperature and offers an explanation for the strikingly rapid and facile exchange of halide ions.
Journal ArticleDOI

A Redox-Flow Electrochromic Window

TL;DR: A low-cost electrochromic window based on a redox-flow system that does not require expensive transparent conductive oxide (TCO) substrates is introduced and demonstrated for the first time and prospects for further development are discussed.
Journal ArticleDOI

Perowskit-Solarzellen: atomare Ebene, Schichtqualität und Leistungsfähigkeit der Zellen

TL;DR: The perovskite solar cells (PSCs) have made tremendous progress in recent years due to exceptional material properties such as high panchromatic absorption, charge carrier diffusion length and a sharp optical band edge.
