Abstract
Issues related to the thermal stability of front contacts, based on Cr-Au and Cr-Au-Ag-Au, to GaSb-based photovoltaic cells have been considered at the operational (the cell temperature is 50 oC) and standard conditions as well as at the forced thermal degradation (at 125 and 200 oC). It is shown that the photovoltaic converter with the silver-containing contact is preferable in terms of the stability of contact resistivity, external quantum yield, FF, VOC, and therefore, the cell efficiency and lifetime. The durability of the cells is determined at operational and elevated temperatures.
