This paper is a collaboration between Renew-PV members affiliated to research units in Romania, Spain, Morocco and Belgium. The article published in Progress in Photovoltaics explores the synthesis of Cu2(Zn,Cd)SnS4 at high temperatures as a route for high-efficiency solar cells. The highest PCE of 10.4% was achieved at an optimal sulfurization temperature of 680°C, attributed to large-grain structures, uniform Cd distribution, optimal absorber bang gap of 1.48 eV, and suppressed deep defects. Voids are present at CZCTS/Mo interface which might act as rear contact passivation layers while the remaining contacts will collect the charges and will keep in the same time a good adherence of the absorber films. The formation of these passivation voids is beneficial in terms of reducing recombination at rear contact, without affecting the adherence of the films and the integrity of the final solar cells.
