摘要：
A method for manufacturing a photovoltaic device includes a step of depositing one of an amorphous layer of ZnTe and a multilayer stack of Zn and Te adjacent a semiconductor layer. The one of the amorphous layer and the multilayer stack is then subjected to an energy impulse at a temperature equal to or greater than its critical temperature. The energy impulse results in an explosive crystallization to form a polycrystalline layer of ZnTe from the one of the amorphous layer and the multilayer stack.
