Abstract:

Interligand electron transfer (ILET) may be an essential parameter for the injection ofan electron from the dye into the semiconductor surface of a dye sensitized solar cell(DSSC). Without an eﬃcient injection, competing recombination paths may become apparent. For the future development and design of DSSCs, with the hope of increased energy conversion eﬃciencies, the ILET dynamics is of great importance. For a long time, the most impressive DSSCs were sensitized with polypyridyl ruthenium dyes for which injection has shown to vary from sub-ps to ns duration. It may therefore be crucial to ﬁnd

Abstract:

The design of dyes for NiO-based dye-sensitized solar cells (DSSCs) has drawn attention owing to their potential applications in photocatalysis and because they are indispensable for the development of tandem dye-sensitized solar cells. The understanding of the electron transfer mechanisms and dynamics is beneficial to guide further dye design and further improve the performance of photocathode in solar cells and solar fuel devices. Time-resolved spectroscopy techniques, especially femtosecond and nanosecond transient absorption spectroscopy, supply sufficient resolution to get insights into t

Abstract:

Photoinduced electron transfer is a fundamentally interesting process; it occurs everywhere in the natural world. Studies on electron transfer shed light on questions about the interaction between molecules and how the dynamics of these can be utilized to steer the electron transfer processes to achieve a desired goal. The goal may be to get electrons to the electrode of a solar cell, or to make the electrons form an energy rich fuel such as hydrogen, and it may also be an input or output for molecular switches. The importance of electron transfer reactions will be highlighted in this thesis,

Abstract:

When high intensity laser light is focused into a gaseous target, high energy photons can be produced through the strongly nonlinear effect of high order harmonic generation. For a 30 fs, 800 nm or 1400 nm wavelength laser pulse, the result is a train of attosecond pulses produced at odd harmonic frequencies of the driving laser field, spanning energy ranges into the 100s eV. These attosecond pulses can access timescales characteristic to the movement of electrons in atoms, and by exploiting their properties as an ultrafast probe, electron dynamics in evolving atomic systems can be observed.

Abstract:

The solid-state mesoscopic solar cells (sMSCs) have been developed as a promising alternative technology to the conventional photovoltaics. However, the device performance suffers from the low hole-mobilities and the incomplete pore filling of the hole transport materials (HTMs) into the mesoporous electrodes. A variety of HTMs and different preparation methods have been studied to overcome these limitations. There are two types of sMSCs included in this doctoral thesis, namely solid-state dye-sensitized solar cells (sDSCs) and organometallic halide perovskite based solar cells. Two different

We employ an extreme ultraviolet (XUV) pulse to impulsively excite dipole polarization in atoms or molecules, which corresponds to coherently prepared superposition of excited states. A delayed near infrared (NIR) pulse then perturbs the fast evolving polarization, and the resultant absorbance change is monitored in dilute helium, dense helium, and sulfur hexafluoride (SF6) molecules. We observe and quantify the time-dependence of various transient phenomena in helium atoms, including laser-induced phase (LIP), time-varying (AC) Stark shift, quantum path interference, and laser-induced continu
