Abstract:

The counter electrode (CE) is an important part of a quantum dot-sensitized solar cell (QDSSC). Improving CE performance is an effective approach to enhance the photovoltaic conversion efficiency of QDSSCs. In this paper, the required properties of CEs are briefly introduced. Recent progress in the study and fabrication methods of QDSSC CEs composed of various materials, including metals, conductive polymers, carbon, metal sulfide, other inorganic metallic compounds, and composites, are reviewed. CEs made of inorganic metallic compounds like copper sulfide, cobalt sulfide, and lead sulfide are the most widely studied because of their high catalytic ability and low cost. Meanwhile, research on CEs made of conductive polymers, new carbon materials, and a variety of composite materials is expanding because of their respective advantages.

Key words: Quantum dot-sensitized solar cell, Counter electrode, Conductive polymer, Carbon material, Metal sulfide
