Abstract [en]

Dye-sensitized solar cells with sub-5 mu m-thick Pt/SiC-P (1.79 at.% Pt), Pt/SiC-M (0.45 at.% Pt), and Pt/SiC-R (0.39 at.% Pt) counter electrode (CE) films fabricated by using three different processes produced power conversion efficiencies of 6.82, 7.64, and 7.04% that reached 86.5, 97.0, and 89.3 %, respectively, of the level obtained by using a print-Pt CE (7.88 %). These materials can reduce the cost of CEs and solve challenges involving Pt.
