Extremely low trap-state energy level perovskite solar cells passivated using NH2-POSS with improved efficiency and stability

J. Mater. Chem. A, 2018, 6,6806-6814
DOI: 10.1039/C7TA11345E, Communication
Na Liu, Qin Du, Guangzhong Yin, Pengfei Liu, Liang Li, Haipeng Xie, Cheng Zhu, Yujing Li, Huanping Zhou, Wen-Bin Zhang, Qi Chen
The defects at perovskite film surface could be passivated effectively using a derivative of polyhedral oligomeric silsesquioxane with an amino-group (NH2-POSS). The extremely low trap-state energy level (0.045 eV) was obtained by temperature-dependent admittance measurements. Both stability and efficiency in devices have been approved.

III–V-on-silicon solar cells reaching 33% photoconversion efficiency in two-terminal configuration

III–V-on-silicon solar cells reaching 33% photoconversion efficiency in two-terminal configuration, Published online: 02 April 2018; doi:10.1038/s41560-018-0125-0

As silicon solar cells are reaching their optimal efficiencies, below 30%, multi-junctions are being developed to increase the electrical power output over the same area. Here, Cariou et al. use wafer-bonding to fabricate two-terminal silicon III–V tandem cells that reach efficiencies above 33%.
