Description

  • Content Description: During this period, work continued on studies of three manufacturing sequences for solar cells based on ion-implanted junctions, furnace annealing, screen-printed contacts, and spray-on antireflection (AR) coatings. The starting material has been primarily solar-grade, n- and p-type 3-in.-diameter wafers; in addition, a small quantity of dendritic web has been received. A total of 1500 solar cells has been fabricated and evaluated. As a result of this work, two problems areas have not been identified relating to materials and process compatibility. First, screen-printed thick-film inks do not contact ion-implanted junctions as well as diffused junctions. Second, it was found that the previously determined optimum ion implantation/anneal process must be modified to accommodate the starting silicon material. Discounting the above compatibility problems, evaluations and comparisons of the three manufacturing sequences were made with regard to the performance data accumulated for each sequence and its effect on cost-effectiveness. In cell interconnection and panel assembly, a solder reflow process has been demonstrated in which the cells are individually tabbed and then placed in an array which is soldered by means of a bank of infrared lamps which traverse the array. With the present system, this latter process is accomplished at a rate of 1 linear ft of array/minute.
