Cadmium sulfide/copper sulfide heterojunction cell research. Quarterly technical progress report, June 1-September 30, 1979
Off-stoiciometry CdS coatings with resistivities of about 10..cap omega..-cm have been deposited by a cyclic reactive sputtering process where the H/sub 2/S injection is periodically switched on and off. Cells with CdS layer fabricated in this way have yielded efficiencies of about 0.6% with short circuit currents of about 3.5 mA/cm/sup 2/, open circuit voltages of about 0.43V, and fill factors of about 0.40. CdS resistivity control by In doping has been achieved both by diffusion from a pre-deposited In layer and by using an In-doped Cd sputtering target. Resistivities of about 30..cap omega..-cm are achieved in CdS coatings about 5 um thick deposited at 250/sup 0/C over 50 nm thick In layers. A Cd cathode doped with 1 atomic percent In has yielded CdS coatings with resistivities of about 0.1 ..cap omega..-cm at substrate temperatures in the 100 to 300/sup 0/C range. Cells fabricated from the 0.1 ..cap omega..-cm CdS with a 0.5 um undoped layer adjacent to the junction have yielded encouraging diode characteristics with a strong photovoltaic effect and will be used to an optimization study. Cu/sub x/S coatings deposited onto CdS under various conditions have been found to have the same properties as those deposited onto …

Analysis of regional banks' efforts to promote energy conservation among commercial customers. Task II
The study approach explored the hypothesis that regional banks can play an important role in disseminating energy conservation information to their commercial/industrial customers. The four phases of the study are described in detail. (MCW)

Municipal waste energy recovery
Materials recovery and energy recovery from municipal solid waste, offering at least a partial solution to a city's solid waste management and disposal problem, are discussed. The most important barriers and issues which relate to energy and materials recovery from waste in urban areas are discussed. Energy recovery practices and processes, environmental issues, and municipal market economics are considered. (MCW)

Analysis of options for a solar development bank. Task VI
Financial barriers which hinder the use and acceptance of solar technology in the building and industrial markets are identified. The barriers fall under three categories: risk, liquidity, and subsidy. Policy initiatives that can be used to overcome financing barriers which hinder the use of solar technology are briefly mentioned. These include direct lending programs operated by the government or by private banks and secondary financing organizations which provide liquidity and security to mortgage lenders. Policy options considered to accomplish the objectives of the initiatives and the evaluation of each option is presented. Options considered are: to modify existing governmental programs and institutions so that these institutions more effectively promote the use of solar energy; to create a new and separate institution to undertake a number of financing functions; and to create a direct federal loan program. The proposed functions of a Solar Development Bank are specifically examined. Information on functions and participants in the secondary mortgage market is discussed in the appendix. The text of a presidential speech on the technically feasible use of solar powered units is given. (MCW)

Synthesis of block copolymers of methyl siloxane, phenyl siloxane, vinyl siloxane, etc
Synthesis of homo poly(dimethylsiloxane) PDMS, homo poly(diphenylsiloxane PDPS, and di- and tri- block copolymers of PDMS and PDPS have been carried out by anionic living polymerization, using the following reagents: hexamethylcyclotrisiloxane, HMTS and hexaphenylcyclotrisiloxane, HPTS (monomers), n-BuLi and dilithium diphenyldisilanolate, DLS (initiators), DMSO and THF (promoters) and Toluene (solvent). Lithium based catalysts are used in order to minimize siloxane rearrangement (equilibration) reactions.

Electric and Hybrid Vehicle System Research and Development Project: Hybrid Vehicle Potential Assessment. Volume VIII. Scenario generation
Scenarios are described which have been generated in support of the Hybrid Vehicle Potential Assessment Task under the JPL Electric and Hybrid Vehicle Systems Research and Development Project. The primary function of the scenario generation is to develop a set of consistent and credible forecasts required to estimate the potential impact of hybrid vehicles on future petroleum consumption in the USA, given a set of specific electric, hybrid and conventional vehicle designs. The forecasts are limited to the next 32 years (1978 to 2010. The four major areas of concern are: population and vehicle fleet size; travel patterns and vehicle fleet mix; conventional vehicle technology (Otto baseline); battery technology; and prices. The forecasts have been generated to reflect two baseline scenarios, a Petroleum Conservation Scenario (Scenario A) and an Energy Conservation Scenario (Scenario B). The primary assumption in Scenario A is higher gasoline prices than in Scenario B. This should result in less travel per car and an increased demand for smaller and more fuel efficient cars (compared to Scenario B). In Scenario B the primary assumption is higher prices on cars (new as well as used) than in Scenario A. This should lead to less cars (compared to Scenario …
