研究目的
Investigating the development of efficient bifacial, color-tunable semitransparent perovskite solar cells for building integrated photovoltaics.
研究成果
The study successfully demonstrated efficient bifacial, color-tunable ST-PSCs using CuSCN as the HTM, achieving high bifacial factors and equivalent efficiencies. The color tunability across the visible spectrum without compromising efficiency makes these ST-PSCs promising for BIPV applications.
研究不足
The study acknowledges the challenge of balancing color tunability with power conversion efficiency, especially with thinner ITO electrodes which increase series resistance. The need for antireflection coatings to minimize reflection losses is also noted.
1：Experimental Design and Method Selection:
The study employed a n-i-p architecture for ST-PSCs using CuSCN as the hole transporting material. The methodology included dynamic spin coating for CuSCN deposition and DC sputtering for ITO electrode deposition.
2：Sample Selection and Data Sources:
Triple-cation perovskite was used as the active layer. The samples were prepared on FTO glass substrates.
3：List of Experimental Equipment and Materials:
Equipment included a UV-Vis-NIR Spectrophotometer, FESEM, and a solar simulator. Materials included CuSCN, ITO, and perovskite precursors.
4：Experimental Procedures and Operational Workflow:
The process involved cleaning FTO substrates, depositing TiO2 layers, spin-coating perovskite, applying CuSCN, and sputtering ITO.
5：Data Analysis Methods:
Optical properties were analyzed using FEM simulations. Photovoltaic performance was evaluated using J-V measurements and EQE spectra.
