Vacuum deposited polycrystalline silicon films for solar cell applications. Quarterly report, September 15-December 31, 1979

Description: Polycrystalline silicon films 14-22 ..mu..m thick and with average grain diameters of 20-40 ..mu..m were deposited by vacuum deposition onto both ceramic and sapphire substrates which were previously coated with a thin (1-2 ..mu..m) TiB/sub 2/ conducting layer. The large grains are the result of an interaction in the initial growth stages between silicon and TiB/sub 2/. SIMS studies of B/Ti/Al/sub 2/O/sub 3/, B/Al/sub 2/O/sub 3/, and Ti/Al/sub 2/O/sub 3/, interactions are reported as part of a … more

Vacuum deposited polycrystalline silicon films for solar cell applications. Second quarterly technical progress report. January 1-March 31, 1980

Description: A careful study of a specially formed thin silicon layer on TiB/sub 2/-coated sapphire reveals that the interaction layer of TiSi/sub 2/ is composed of larger grains. Processing steps were developed which lead closer to the goal of fabricating polycrystalline silicon photovoltaic devices completely by vacuum deposition. Both n-type and p-type silicon are now being deposited. New deposition masks were made for depositing the n-regions upon the p-layers. New electrode deposition masks were also m… more

Vacuum deposited polycrystalline silicon films for solar cell applications. Quarterly report, 1 April-30 June 1980

Description: Polycrystalline p-type films were vacuum deposited onto TiB/sub 2/ coated alumina and sapphire substrates. Epitaxial layers were also formed on single crystal silicon substrates. Junctions in the layers were created by both gaseous diffusion in a tube furnace and by vacuum deposition. The TiB/sub 2/ vacuum deposited bottom electrodes have resistivities between 30 and 40 ..mu.. ..cap omega..-cm. All-vacuum-deposited solar cells were fabricated for the first time. Efficiencies approaching those i… more

Geothermal energy development in the Eastern United States. Technical assistance report No. 4. Geothermal space heating: Pittsville Middle/Elementary School, Pittsville, Maryland

Description: A technical evaluation was made to determine whether geothermal energy obtained from a well could be used to space heat the new school building being constructed as well as the existing elementary wing of the Pittsville School. The first part deals with space heating the new school building only; the second part pertains to space heating the new school building together with the new existing wing. An addendum was added for new well and production pump costs. (MHR)

Solar wind iron abundance variations at solar wind speeds > 600 km s/sup -1/, 1972 to 1976

Description: We have analyzed the Fe/H ratios in the peaks of high speed streams (HSS) during the decline of Solar Cycle 20 and the following minimum (October 1972 to December 1976).

Reentry response of the light weight radioisotope heater unit resulting from a Venus-Earth-Earth Gravity Assist maneuver accident

Description: Reentry analyses consisting of ablation response, thermal response and thermal stress response have been conducted on the Light Weight Radioisotope Heater Unit for Galileo/VEEGA reentry conditions. Sequential ablation analyses of the LWRHU aeroshell, the fuel clad, and the fuel pellet have been conducted in reentry regimes where the aeroshell has been deemed to fail. The failure criterion for ablation is assumed to be recession corresponding to 50% of the wall thickness (the design criterion re… more
