Single crystal perovskite solar cell with 17.8% efficiency
The solar cell was manufactured with crystals that were grown directly onto indium tin oxide (ITO) substrates covered with hole transport layer (HTL). These substrates have a controlled thickness of tens of micrometers and area of tens of mm2. The device showed an efficiency of 17.8%, a short-circuit current of 21.0 mA cm−2, an open-circuit voltage to 1.08 V, and a fill factor to 78.6%.
A step forward for single-crystal perovskites
Scientists in the United States have developed a lithography-based process for the fabrication of single-crystal perovskites. Thin films made using this process have been integrated into a range of devices, including solar cells, and have demonstrated better stability performance than their more commonly researched polycrystalline counterparts.
Scientists set new efficiency record for single crystal perovskite
Scientists at Saudi Arabia’s King Abdullah University of Science Technology have set a new efficiency record of 21.09% for a single crystal perovskite. The researchers say this highlights a place for the technology to develop alongside the multicrystalline versions which are progressing toward commercialization.
