Chalcopyrite Solar Cells
Škvarenina, Ľubomír
Thin-film chalcopyrite based Cu(In;Ga)Se2 solar cells with a metal wrap through interconnection were investigated by non-destructive methods in our research. The primary focus of this investigation was a detection and a localization of microstructural defects in this type of Cu(In;Ga)Se2 solar cells. A combination of a visible and near infrared electroluminescence with a lock-in thermography was used for these purposes. Mainly the electroluminescence was a very sensitive tool for an indication of pre-breakdown sites influenced by a trap-assisted tunneling or stress-induced leakage currents. A strong correlation between electroluminescence maps and lock-in thermograms was obtained after a local breakdown accompanied by a creation of permanent defect.
Dark J–V Characteristics Model Of Chalcopyrite-Based Solar Cells
Škvarenina, L’ubomír
An equivalent circuit model of the current parasitic pathways is proposed to describe a behaviour of dark current density–voltage characteristics of chalcopyrite-based solar cells in order to understand a shunting behaviour between the ZnO:Al/i-ZnO/CdS/Cu(In;Ga)Se2/MoSe2/Mo/Ti/TiN layers. The model fitting with a parameter extraction is evaluated for the sample before and after an appearance of a permanent breakdown to prove an accurate response of the proposed model to an ohmic and non-ohmic component shift.
