Chemical composition of anodic oxides grown on lightly doped p-type InP have been investigated by XPS. Anodization was performed in the constant current density (Jc) mode using an ortho-phosphoric acid solution mixed with acetonitrile (ACN). The elec

Using a detailed simulation model of p/sup +/nn/sup +/ and n/sup +/pp/sup +/ indium phosphide (InP) homojunction solar cells, the authors have conducted extensive parametric variation computer simulation runs to help arrive at near-optimum designs of

The problem of the presently obtained best open-circuit voltage (V/sub oc/) values of n/sup +/pp/sup +/ InP solar cells being considerably smaller than those predicted by basic theory is theoretically investigated. The values of some key parameters i

We demonstrate the effectiveness of using wet chemical techniques for Si and Ge planar surfaces to form nanoporous layers, and grow stable passivating oxide layers on planar and porous surfaces, after the front grid metallization step. Our results sh

On bare p/sup +/n (Cd,S) InP diffused solar cells, the authors recorded AMO, 25/spl deg/C V/sub oc/ values exceeding 880 mV. In this work they present some of their most recent results showing much lower carrier removal rates in the emitter of p/sup

A significant reduction of defect densities of n/sup +/p and p/sup +/n InP structures fabricated by closed-ampoule thermal diffusion was obtained after optimizing the diffusion process. For n/sup +/p structures, the lowest etch pit density (EPD) of 6

Cd diffusion and Zn diffusion into n-InP:S (N/sub D/ =3.5*10/sup 16/ and 4.5*10/sup 17/ cm/sup -3/) were performed by a closed ampoule technique at diffusion temperatures from 500 to 600 degrees C by using either high-purity Cd and Zn or Cd/sub 3/P/s

In order to optimize the fabrication of n(+)-p InP solar cells made by closed-ampoule diffusion of sulfur into p-InP:Cd substrates, we have investigated the influence of diffusion conditions on sulfur diffusion profiles. We show that S diffusion in I

Particulate radiation in space is a principal source of silicon solar cell degradation, and an investigation of cell radiation damage at higher base resistivities appears to have implication toward increasing solar cell and, therefore, useful satelli
