Hole-Transporting Materials for Printable Perovskite Solar Cells
Perovskite solar cells (PSCs) represent undoubtedly the most significant breakthrough in photovoltaic technology since the 1970s, with an increase in their power conversion efficiency from less than 5% to over 22% in just a few years. Hole-transporting materials (HTMs) are an essential building block of PSC architectures. Currently, 2,2',7,7'-tetrakis-(N,N'-di-p-methoxyphenylamine)-9,9'-spirobi...
متن کاملMesoscopic TiO2/CH3NH3PbI3 perovskite solar cells with new hole-transporting materials containing butadiene derivatives.
Two new triphenylamine-based hole-transporting materials (HTMs) containing butadiene derivatives are employed in CH3NH3PbI3 perovskite solar cells. Up to 11.63% of power conversion efficiency (PCE) has been achieved. Advantages such as easy synthesis, low cost and relatively good cell performance exhibit a possibility for commercial applications in the future.
متن کاملInvestigation of Triphenylamine (TPA)-Based Metal Complexes and Their Application in Perovskite Solar Cells
Triphenylamine-based metal complexes were designed and synthesized via coordination to Ni(II), Cu(II), and Zn(II) using their respective acetate salts as the starting materials. The resulting metal complexes exhibit more negative energy levels (vs vacuum) as compared to 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (SpiroOMeTAD), high hole extraction efficiency, but low h...
متن کاملStable and efficient hole transporting materials with a dimethylfluorenylamino moiety for perovskite solar cells.
Novel star-shaped hole transporting materials (HTMs) with a bis-dimethylfluorenylamino moiety have been synthesized and evaluated for high performance perovskite solar cell applications. Maximum power conversion efficiency of 14.21% has been achieved by using the HTM with a fused TPA core and the long-term stability was also shown to be comparable with that of .
متن کاملHole-Transport Materials for Perovskite Solar Cells.
The pressure to move towards renewable energy has inspired researchers to look for ideas in photovoltaics that may lead to a major breakthrough. Recently the use of perovskites as a light harvester has lead to stunning progress. The power conversion efficiency of perovskite solar cells is now approaching parity (>22 %) with that of the established technology which took decades to reach this lev...
