Charge transfer refers to the process where an electron moves from a donor molecule or atom to an acceptor, leading to a redistribution of charge that can alter the electronic properties of materials. This phenomenon is crucial in fields like photovoltaics, molecular electronics, and biological systems, where it influences energy transfer and chemical reactivity.

Charge separation refers to the spatial distribution of positive and negative charges, a fundamental process in fields like chemistry and physics. It plays a critical role in phenomena such as the photovoltaic effect, where it enables the conversion of light into electrical energy, and in biochemical processes like photosynthesis, where it drives the initial steps of energy conversion.

Charge Separation

Energy barriers are potential energy thresholds that must be overcome for a chemical reaction or physical process to occur, often determining the rate and feasibility of these processes. They play a crucial role in kinetics and thermodynamics, influencing reaction pathways and the stability of reactants and products.
