In the Si film crystallized by a linearly polarized Nd:YAG laser beam, the grain boundaries are aligned periodically. This periodic structure is produced by the periodic beam energy density profile generated by interference between the coherent incident and high order diffracted beams. The effect of multiple reflection in the Si film was investigated theoretically on the surface structure of the crystallized film. The suitable thickness for this method was estimated by this theoretical analysis and verified experimentally.

We have analyzed field-test data collected from grid-connected PV systems for residential houses in the Tokyo area from August 1999 to July 2000 in detail, focusing on module temperature. It was demonstrated that the PV systems operated in the wide temperature range, and that the module temperature range in which the PV systems operated differed greatly even for the same type of module due to the installation environment. Further, we have discussed the influence of module temperature on annual output energy quantitatively. These results indicate that it is very important to consider the temperature characteristics of solar cells and the operation temperature of modules.

The characteristics of multi-junction solar cell under concentration were evaluated by SPICE (Simulation Program with Integrated Circuit Emphasis). We developed the multi-unit model and analyzed the affect of the chromatic aberration and intensity distribution for the multi-junction cells. In the multi-unit model, the same numbers of units as grid numbers are installed for every electrode, and the units were connected each other with the lateral resistances. In order to obtain the generation current from each diode, we measured intensity of concentrated light through the pinhole using single-junction solar cells consisted of InGaP, GaAs and Ge as detectors. By using the multi-unit model, we could successfully calculate the electrical cell performances taking the chromatic aberration and intensity distribution into account, and the calculated value agreed well with the experimental value. The multi-unit model will be very useful for cell designs and performance analysis of the concentrator cells.
