Crystal Control Of CdTe Electro-Deposits By Use Of Intense Magnetic Field

CdTe semi-conducting materials have been expected as solar cell materials because its theoretical energy conversion ratio is very high. The actual efficiency still low, however, many research works have been done in order to improve the efficiency. And crystal orientation is one of possibilities for that. In this work, a new method using intense magnetic field for a control of texture of CdTe crystals will be proposed, where the CdTe film was electro-deposited under an intense magnetic field. CdTe is less affected by magnetic field, because of its cubic structure, but Cd or Te has hexagonal structure, which is sensitive for magnetic field. In this paper, crystal orientation of Cd or Te film, which can be utilized as basic layer for CdTe deposition, will be developed.
