This annual report is for the second year of a program to investigate the characteristics of the components and the total system using sunlight concentrated onto solar cells. The second year was primarily to experimentally investigate the conclusions of the first year of analytical studies. Cells have been fabricated that are designed for different intensities. Typically the efficiency of a cell will increase from its 11 percent at AM1 peak to efficiency at the designed concentration level and return to its initial efficiency at about 3 times its designed concentration level. The developed cells have been tested under high intensity simulators and in concentrated sunlight and have shown to have the predicted response. The experimental testing of passive cooling limitations for cooling cells with just finned arrangements in the back of the cell has been completed in the controlled environment of a wind tunnel. These experiments have confirmed the heat transfer coefficients that had been used in the analytical studies. Testing was done to collect heat transfer coefficients for actual wind conditions and these data show good agreement with the controlled wind tunnel data. Four photovoltaic/concentrator system experiments have been started with CR of about 3, 10, 25, and 100. …

Nuclear graphite grades H-451 (Great Lakes Carbon Company) and TS-1240 (Union Carbide Corporation) are described and property data are presented for the unirradiated state. Properties measured included bulk density, ultimate tensile strength, modulus of elasticity, Poisson's ratio, thermal expansivity, and thermal conductivity. The data presented represent the minimum and maximum property values of the prototype full-size production logs and are indicative of property values to be expected in commercial production.
