An application of an organic-inorganic perovskite is a perovskite solar cell. This solar cell can usually be fabricated by the three-dimensional cubic perovskite [(MeNH3)MX3]. Doping effects of formamidinium and cesium cations to the A site were also investigated for the perovskite solar cell research. Research on the perovskite solar cell recently received much attention. Power conversion efficiency of this solar cell is more than those of organic photovoltaics (OPV) and dye-sensitized solar cells (DSSC), and the device can be fabricated by a solution method at low cost.
Three Advantages of TCI's Perovskite-Related Products
High Purity
We can provide high purity PbX2 (X = I, Br, Cl) as well as organic onium salts with low water content (eg. MAI, FAI, etc). High purity and low water materials can enhance the perovskite solar cell performance such as efficiency and stability. Highly pure PbX2 shows good solubility in polar organic solvents to be appropriate for solution processable device fabrication of the perovskite solar cell.
Product Variety
We can provide various PbX2 (X = I, Br, Cl) and organic onium salts. A mixed cation perovskite where the A site includes some cations, enables the perovskite solar cell to be efficient and stable.
Scale-Up
We can provide various PbX2 (X = I, Br, Cl) and some dominant organic onium salts in bulk scale. Our bulk production enables the perovskite solar cell to be low cost and large area.
