Towards quantitative interpretation of Fourier-transform photocurrent spectroscopy on thin-film solar cells
Original language description
The method of detecting deep defects in photovoltaic materials by Fourier-Transform Photocurrent Spectroscopy is reviewed. As new materials appear, a prediction of potentially achievable open-circuit voltage is highly desirable. From thermodynamics, a prediction can be made based on the radiative limit, neglecting non-radiative recombination and carrier transport effects. Beyond this, more accurate analysis has to be done. We analyzed a series of hydrogenated amorphous silicon solar cells of different thicknesses at different states of light soaking. Combining empirical results with optical, electrical and thermodynamic simulations, we provide a predictive model of the open-circuit voltage for a given defect density and absorber thickness. We observed that, rather than defect density or thickness, it is the total number of defects, that matters. Alternatively, including defect absorption into the thermodynamic radiative limit gives also useful upper bound to the open-circuit voltage.
