Research on CdTe/Perovskite integration

In the research paper titled ‘4-T CdTe/Perovskite Thin Film Tandem Solar Cells with Efficiency >24%’, researchers investigated the integration of perovskite and cadmium telluride (CdTe) solar cells in a tandem configuration for efficient thin-film solar cells. The study combined commercially established CdTe photovoltaics with next-generation perovskite PV, resulting in a 4-T tandem configuration achieving 23.42% efficiency. With the addition of a refractive index matching liquid, the efficiency increased to 24.2%, surpassing a significant milestone. This marks the first instance of a 4-T CdTe/perovskite thin-film tandem solar cell exceeding a power conversion efficiency (PCE) of 24.2%, representing a remarkable 123.72% increase in overall PCE.
