NOVELTY - The selenium deposition apparatus comprises a chamber, which has a gate for the introduction and withdrawal of a substrate in both sides and an inner expropriation space, a heating element (220) arranged in a lower part of the chamber, a transfer apparatus that has a substrate mounting space in its top and is arranged in an upper end of the heating element, a cracker cell that is designed for spraying selenium molecules and is connected to the top surface of the chamber, where the cracker cell cracks selenium molecules inside the chamber, and a lamp part (250).    USE - The apparatus is useful for depositing selenium on a substrate for fabricating a thin film solar cell.    ADVANTAGE - The apparatus ensures efficient, rapid and easy deposition of selenium on the substrate thus increasing efficiency and quality of the solar cell thin film.    DETAILED DESCRIPTION - The selenium deposition apparatus comprises a chamber, which has a gate for the introduction and withdrawal of a substrate in both sides and an inner expropriation space, a heating element (220) arranged in a lower part of the chamber, a transfer apparatus that has a substrate mounting space in its top and is arranged in an upper end of the heating element, a cracker cell that is designed for spraying selenium molecules and is connected to the top surface of the chamber, where the cracker cell cracks selenium molecules inside the chamber, a lamp part (250) installed at the top surface of the chamber, a fluid path connected to a spray hole, which is surrounded by a heating coil, and a crucible, which is surrounded by the heating coil. The lamp part comprises halogen lamps.
