Energy conversionCharge conversionModelingThe ability to evaluate light energy conversion into electrical energy during capacitance-voltage (photo C–V) is important for developing solar cells. Before this work, unfortunately reliable and accurate energy prediction during photo C–V is impossible due to ...
2.2Hamiltonian and energy spectrum TheHamiltonianof the whole CPB circuit (including its voltage source) is written: (2.3)Hˆ(Ng)=Hˆel+Hˆj=EC(Nˆ−Ng)2−Ejcosθˆ, where the first term corresponds to the electrostatic energy of the circuit,Ng=CgVg/(2e) being the reduced ...
Molecular modeling has been considered indispensable in studying the energy storage of supercapacitors at the atomistic level. The constant potential method (CPM) allows the electric potential to be kept uniform in the electrode, which is essential for a
However, this excess energy (Egopt − ECS) is wasted as heat, resulting in large overall energy loss in the form of low open-circuit voltage (VOC). This fundamental trade-off between the energetic driving force for charge generation and the cell voltage is a reason for the power ...

Relativistic calculations of the charge-transfer probabilities and cross sections for low-energy collisions of H-like ions with bare nuclei A method for solving the time-dependent two-center Dirac equation is developed. The time-dependent Dirac wave function is represented as a sum of atomiclik.....
