Data of Solar Energy Materials

Inorganic Materials - ZnTe
ZnTe Data Page.

Here you will find a some relevant data of photovoltaic materials such as electronic data (e.g. work functions), electrochemical data (e.g. a Pourbaix diagram), physico-chemical data (e.g. melting points).
Although great care is taken to update these data, there is no guarantee for completeness nor for correctness. If you want to contribute to these data, please feel free to send a mail to the webmaster (see email below).
