Solar cells are emerging as serious contenders to rival leading energy sources to generate
electricity for environment friendly renewable and sustainable energy technologies. Earth is …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

At present, fossil fuel-based power generation systems are reducing drastically because of
their less availability in nature. In addition, it produces hazardous gasses and high …

Two-dimensional spectroscopy is a powerful tool for extracting structural and dynamic
information from a wide range of chemical systems. We provide a brief overview of the ways …

The high efficiencies reported for organic solar cells and an almost negligible thermal
activation measured for the photogeneration of charge carriers have called into question …

We address the nature of electrochemically induced charged states in conjugated polymers,
their evolution as a function of electrochemical potential, and their coupling to their local …

Charge separation dynamics after the absorption of a photon is a fundamental process
relevant both for photosynthetic reaction centers and artificial solar conversion devices. It …

Although valuable insights are derived from conventional spectroscopic approaches, the
understanding of a photovoltaic device's operation mechanisms can be limited in ex situ …

Since its first implementation in 2006, in fluorescence detected Fourier transform excitation
spectroscopy of rubidium atoms, phase modulation is being increasingly used in nonlinear …

We have developed coherent two-dimensional (2D) fluorescence micro-spectroscopy which
probes the nonlinear optical response at surfaces via fluorescence detection with sub …
