Although silicon solar cells based on layers less than 50 μm thick have become very popular, little attention has been paid to the role of the underlying silicon substrate. This treatment uses the device simulation program PC-1D and the ray tracing

We use variable temperature Hall effect measurements to determine the doping concentration, impurity compensation, and mobility of n- and p-type liquid phase epitaxy (LPE) silicon layers that are grown from indium solutions onto silicon substrates. O

The internal quantum efficiencies of intrinsic hydrogenated amorphous silicon (a-Si:H) Schottky barrier solar cell structures have been used to determine the effects of the metal/a-Si:H contact on the collection of photogenerated carriers. The result

Pin solar cells were aged under high-intensity illumination at 60 degrees C, well into saturation of their conversion efficiency. The cell characteristics were measured at intervals and were modeled numerically with a quantitative optoelectronic mode

The first-principles computer model AMPS is used to model multijunction solar cell performance. The specific cell modeled uses two a-Si:H absorber layers and an a-SiGe:H absorber layer with all a-SiC:H p/sup +/ layers and all a-Si:H n/sup +/ layers,

Internal photoemission of both electrons and holes was used to investigate the movement of mobility edges in a-Si:H. Shifts of the electron mobility edges were observed with changes in the optical gap, E/sub opt/ due to temperature and incorporation

The performance of a-Si:H p-i-n solar cells with different p-layer thicknesses, front contact barrier heights, and front contact/p-layer hole transport mechanisms were modeled. The authors examined how p-layer material and contact quality influenced

A computer-model study is used to investigate the effects of the distribution of the bandgap discontinuity in a-SiC:H/a-Si:H heterojunction p-i-n solar cells. It is found that the influence of the energy location of the p-layer/i-layer bandgap discon
