Primary reference cell calibrations, at SERI: history and methods

Autor: Daryl R. Myers, Carl R. Osterwald, Keith Emery, R. E. Hart

Publikováno v: IEEE Conference on Photovoltaic Specialists.

The tabular calibration method used at the Solar Energy Research Institute (SERI) for primary reference solar cells is derived and described in detail. An uncertainty analysis shows that the tabular method should have a total uncertainty of +or-1.0%;

Photon‐degradation effects in terrestrial silicon solar cells

Autor: H. W. Brandhorst, J. H. Lamneck, V. G. Weizer, J. D. Broder, R. E. Hart

Publikováno v: Journal of Applied Physics. 50:4443-4449

The effect of instability in terrestrial solar cells and identification of mechanisms involved are presented. The effect is similar to photon-induced degradation in radiation-damaged space solar cells, with reduction in cell output in n(+)/p cells up

Comparative radiation resistance, temperature dependence and performance of diffused junction indium phosphide solar cells

Autor: R. E. Hart, Sorab K. Ghandhi, K. K. Parat, C. K. Swartz, J.M. Borrego, M. Yamaguchi, Irving Weinberg

Publikováno v: Solar Cells. 22:113-124

Indium phosphide solar cells whose p-n junctions were processed by the open tube capped diffusion and by the closed tube uncapped diffusion of sulfur into Czochralski-grown p-type substrates are compared. Differences found in radiation resistance wer

A Geometric Interpretation of Diagnostic Data from a Digital Machine: Based on a Study of the Morris, Illinois Electronic Central Office Illinois Electronic Central Office

Autor: R. E. Hart, J. B. Kruskal

Publikováno v: Bell System Technical Journal. 45:1299-1338

Using the diagnostic data collected for the Morris Central Control malfunction dictionary, we devise a natural concept of “distances” between malfunctions. Ten thousand malfunctions were placed as points in six-dimensional space in such a way tha

Voltage-controlling mechanisms in low-resistivity silicon solar cells—A unified approach

Autor: M. P. Godlewski, V. G. Weizer, R. E. Hart, C. K. Swartz

Publikováno v: IEEE Transactions on Electron Devices. 33:156-158

An experimental technique is used to determine the relative values of the base and emitter components of the dark saturation current of six types of high-voltage low-resistivity silicon solar cells. One of the suprising findings is the suggestion tha
