Thin Film Solar Cells

 

AkzoNobel also plays a role in the fast-growing solar cell market. We have developed new technology for the production of high purity diethyl zinc, which is used by thin film solar cell manufacturers to create the all-important TCO layer.

We pioneered the large-scale production of diethyl zinc (DEZn) and have been producing commercial quantities in La Porte (TX-USA) since the 1960s. Main applications are as ZnO precursor for the TCO layer in thin film solar cells and in pharmaceutical synthesis. Our product grade specifically aimed to serve the needs of the solar cell industry is called DEZn TCO.

Recognizing increasing worldwide requirements, we expanded capacity in 1996 with the construction of a major metal alkyl manufacturing facility near Rotterdam, the Netherlands. We now produce diethyl zinc, including the TCO grade, at both our La Porte and Rotterdam sites, thus ensuring security of supply to our global customer base.

Highest purity

We use leading edge processes, purification and transfilling techniques that ensure the repeatable and consistent delivery of the highest purity DEZn TCO in each cylinder that we supply. We apply state-of-the-art techniques such as ICP-AES for trace metal analysis to meet customers’ demands.
