After finding a way to make spiro-OMeTAD, a popular perovskite solar cell hole transport layer, less prone to heat-induced crystallization, researchers at Georgia Institute of Technology are now ...
They then remade the solar cell on this substrate layer by layer with the recovered perovskite crystals, spiro-OMeTAD, and gold. “The question always is ‘is recycling worth doing?’” You says.
The ions migration and de-doping reactions caused by conventional doping seriously jeopardizes the thermal stability of perovskite solar cells (PVSCs) based on spiro-OMeTAD as hole transport layer ...
2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9-spirobifluorene (spiro-OMeTAD) is an irreplaceable hole transport material (HTM) for high-performance n-i-p perovskite solar cells (PSCs), and an ...
Researchers in China have proposed a new lithium-free doping strategy to fabricate spiro-OMeTAD-based hole transport layers (HTLs) for applications in perovskite solar cell. A PV device built with ...
In this work, we study the outdoor and indoor photovoltaic performance of LHP-based devices utilizing Spiro-OMeTAD as the hole-transport material with commonly used dopants such as lithium bis ...
Undoped Spiro-OMeTAD devices also have lower hysteresis at very low-light levels and an open-circuit voltage of ≈0.65 V at 50 lux, thus making them more reliable in these conditions.
To improve the charge transport ability of spiro-OMeTAD, lithium trifluoromethanesulfonyl imide (Li-TFSI) is required to mediate the reaction between oxygen and spiro-OMeTAD.
We report a high-efficient green CdSe/ZnS quantum-dot light-emitting diode (QLED) using 2,2’,7,7’-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9’-Spirobifluorene (Spiro-OMeTAD) as an electron buffer layer ...
