摘要:
A liquid-phase growth method for immersing a polycrystalline substrate in a melt in a crucible wherein crystal ingredients are dissolved, thereby growing poly crystals upon the substrate, comprises a first step for growing poly crystals to a predetermined thickness, and a second step for melting back a part of the poly crystals grown in the first step in the melt, wherein the relative position between the substrate and melt is changed between the first step and second step, bringing melt with different temperature into contact with the polycrystalline surface. The obtained poly crystals have properties rivaling those of poly crystals used in conventional solar cells but with little risk of trouble such as line breakage of grid electrodes in application to solar cells, and can be obtained in great quantities at low costs.

There is provided a functional ZnSe:H deposited film composed of zinc atoms, selenium atoms, and at least hydrogen atoms, with the content of hydrogen atoms being 1 to 4 atomic % and the ratio of crystal grains per unit volume being 65 to 85 vol %. It is capable of efficient doping and is stable to irradiation. It can be made into a high conductivity p-type of n-type ZnSe:H:M film by doping. It can be efficiently deposited on a non-single crystal substrate such as metal, glass, and synthetic resin which was incapable of efficient depositing. Thus the invention makes it possible to form a high-functional device such as a photovoltaic element of ZnSe film on a non-single crystal substrate.
