Photovoltaic cell de-plating
Solar Energy Materials and Solar Cells
The bottom SHJ cell was connected in series with the top perovskite solar cell via an indium tin oxide (ITO) recombination layer. The planar perovskite solar cell was entirely fabricated at low temperature (≤100 °C) starting by spin coating the hole transport layer poly[bis(4-phenyl)-(2,4,6-trimethylphenyl)amine] (PTAA) onto ITO.
