Abstract: An improved thin-film, large area solar cell, and methods for forming the same, having a relatively high light-to-electrical energy conversion efficiency and characterized in that the cell comprises a p-n type heterojunction formed of: (i) a first semiconductor layer comprising a photovoltaic active material selected from the class of I-III-VI2 chalcopyrite ternary materials which is vacuum deposited in a thin "composition-graded" layer ranging from on the order of about 2.5 microns to about 5.0 microns ( SIMILAR 2.5 mu m to  SIMILAR 5.0 mu m) and wherein the lower region of the photovoltaic active material preferably comprises a low resistivity region of p-type semiconductor material having a superimposed region of relatively high resistivity, transient n-type semiconductor material defining a transient p-n homojunction; and (ii), a second semiconductor layer comprising a low resistivity n-type semiconductor material; wherein interdiffusion (a) between the elemental constituents of the two discrete juxtaposed regions of the first semiconductor layer defining a transient p-n homojunction layer, and (b) between the transient n-type material in the first semiconductor layer and the second n-type semiconductor layer, causes the transient n-type material in the first semiconductor layer to evolve into p-type material, thereby defining a thin layer heterojunction device characterized by the absence of voids, vacancies and nodules which tend to reduce the energy conversion efficiency of the system.

Patent EP-0166239-B1 (EP)
IPC: C21D9/52
Filed: 1985-05-25
Granted: 1989-09-27
Abstract: For the production of a reinforcing steel with a higher yield point and good weldability and toughness, microalloying elements are alloyed with the steel and their proportion represents 0.02 and 0.06% vanadium and 0.01 to 0.02% nitrogen, said proportions not being sufficient for achieving a higher yield point of at least 450 N/mm2. However, this is reached if the rolling stock undergoes controlled, but relatively limited cooling during or after rolling, in such a way that the compensating temperature of the steel reaches at least 700 DEG  C. Due to the fact that the microalloying elements are only alloyed in small quantities and only relatively small water quantities are required, reinforcing steel can be economically produced. In addition, the process permits coiling in the case of wire rolling and can also be used on other rolled steel products.
