VOTCA-XTP is a library which allows you to calculate the electronic properties of organic materials, e.g. - excited state properties via GW-BSE - spectra using QM/MM in conjunction with excited state treatment via GW-BSE - energetic disorder for electrons/holes and excitons via QM/MM or fast MM/MM multipole methods - electron and hole mobilities using electronic couplings and kinetic Monte-Carlo - electron, hole, singlet and triplet diffusion constants using electronic couplings and kinetic Monte-Carlo.
