What causes photovoltage perturbation in a perovskite solar cell?
Time-dependent charge-carrier dynamics simulation of the perovskite solar cell reveals that the perturbation photovoltage is generated from the non-equilibrium charge accumulation in the CTLs and is decayed due to the defect-assisted non-radiative charge recombination in the absorber layer.
How does a photovoltaic cell generate electricity?
Photovoltaic cell is the core component of the solar system and generate electricity when sunlight bombard on it. It directly convert the sun's energy into electricity which can be easily transported and converted to other forms for the benefit of society.
