Electrical Spectroscopy

About

The performance of a solar cell is limited by power loss mechanisms that can originate from its different layers and their interfaces. Electrical spectroscopy measurements, consisting of small-perturbation methods both in the time and frequency domain, allow separation and parameterization of these different loss mechanisms. These measurements are combined with drift-diffusion simulations to obtain an in-depth understanding of the physics of operation of the solar cell.
