Tokyo Chemical Industry (TCI), a global supplier of laboratory chemicals and specialty materials, launched a new high-performance hole collecting material (HCM), that can be used to enhance the performance of inverted perovskite solar cells, as it efficiently collects holes from the perovskite layer.
TCI's new 3PATAT-C3 is a SAM formation reagent, with face-on orientation to the substrate surface. It strongly binds to the ITO layer, has a high coverage ratio and it offers efficient charge recovery from the perovskite layer. The material is now available in high purity, and preparations are underway with a view to large-scale supply. See here for more info.
