A copper-metalloporphy in metal-organic framework material (Cu-TCPP) was synthesized via a liquid-phase epitaxy approach. Afterward, a transparent Cu2S@N-doped carbon film was in situ fabricated using Cu-TCPP as a template, and was directly used as a counter electrode for bifacial CdS/CdSe quantum-dot sensitive solar cells (QDSSC). The morphology, construction, and performance of Cu2S@N-doped carbon film were also investigated. During the sulfidation process, the cupric ions in Cu-TCPP thin film were transformed into Cu2S nanoparticles, while the nitrogen-rich ligand (TCPP) was in situ carbonized, generating N-doped carbon and leading to the formation of a uniform Cu2S@N-doped carbon film. After the sulfidation of Cu-TCPP, the original nanosheet morphology is maintained and uniform Cu2S nanoparticles are embedded on the nanosheet surface. As a result, the transparent Cu2S@N-doped carbon film exhibits greater power conversion efficiencies (i.e., 4.16% and 3.72%) rather than Pt (i.e., 2.39% and 1.73%) from the front and rear irradiations, respectively. Based on the analysis of the systematic electrochemical data by cyclic voltammetry test, electrochemical impedance spectroscopy and Tafel test, a transparent Cu2S@N-doped carbon film with a low charge-transfer resistance, a fast ion diffusion rate, and an excellent catalytic ability is obtained for Sn2-/S2- redox reaction. As a result, the superior photovoltaic performance of bifacial CdS/CdSe QDSSC can be achieved.
