Model validation and sensitivity analysis of solar collector loops. Final technical report

Description: The experimental solar collector systems at Middlebury College have been modified to permit short time resolution studies of solar collector loop performance. A variety of experiments have been performed to measure the following system properties: (a) collector efficiency, (b) collector response to step changes in insolation, (c) collector response to the introduction of cold inlet water, and (d) pump cycling as a function of control sensor location and set points. Data from these experiments h… more

Alternative economic evaluation measures for solar industrial process heat

Description: The measures most commonly used to assist decision-makers in evaluating the economic merits of solar energy projects are described and compared. An example is given to illustrate the economic evaluation measures and the results are applied to a solar industrial process heat project. Four widely used economic measures are: net present value, benefit-cost ratio, internal rate of return, and payback period. (MHR)

Plating on difficult-to-plate metals: what's new

Description: Some of the changes since 1970 in procedures for plating on such materials as titanium, molybdenum, silicon, aluminum, and gallium arsenide are summarized. While basic procedures for plating some of these materials were developed as many as 30 to 40 years ago, changes in the end uses of the plated products have necessitated new plating processes. In some cases, vacuum techniques - such as ion bombardment, ion implantation, and vacuum metallization - have been introduced to improve the adhesion … more

Photovoltaic mechanisms in polycrystalline thin film silicon solar cells. Quarterly technical progress report No. 1, July 30-October 31, 1980

Description: Major accomplishments during the first quarter of the contract period are reported. Small area diode fabrication and analysis has been continued. This technique has further been applied to many RTR ribbons. An optical technique for determination of crystallite orientations has been placed in operation. This technique has many distinct advantages. These are: (1) rapid; (2) can be set-up very inexpensively; (3) well suited for polycrystalline substrates of small grain size; and (4) can easily cha… more
