...Dong-Jun Kim; Dae Hyun Kim; Sujala Bhattarai; Jae-Heun Oh One of the unique features of photovoltaic (PV) modules is the power drop that occurs as the silicon temperature increases due to the characteristics of the crystalline silicon used in a solar cell. To overcome this reduction in power...

...A. Al Tarabsheh; I. Etier This paper analyzes the ideality factor of amorphous silicon (a-Si:H) solar cells as a function of both the thickness of the intrinsic layer and the applied voltage to the cells. The ideality factor in this work is extracted from the current/voltage characteristic...

... energy predictions varied between 1% and 8%, again with the exception of the tandem-junction amorphous silicon modules. The large difference between measured and predicted results for the tandem-junction modules is attributed to performance degradation. Power measurements of the tandem-junction amorphous...

...Claudia Funke; Susann Wolf; Dietrich Stoyan Solar silicon wafers are mainly produced through multiwire-sawing. This sawing implies microcracks on the wafer surface, which are responsible for brittle fracture. In order to reduce the sawing-induced cracks, the wafers are damage etched after sawing...

...W. Durisch; F. von Roth; W. J. Tobler In a first and completely new approach, a vacuum plasma-spray coating technique was used to deposit selective emitting rare-earth oxide films of ytterbia ( Yb 2 O 3 ) on porous silicon-infiltrated silicon carbide foams (Si–SiC). The plasma-spray coating...

...A. T. Naveed; E. C. Kang; E. J. Lee The electrical power generated by a polycrystalline silicon photovoltaic (PV) module mounted on an unglazed transpired solar collector (UTC) has been studied and compared to that of a PV module without UTC for a quantitative analysis of electrical output and its...

...James T. McLeskey,, Jr.; Pamela M. Norris The femtosecond energy diffusion sensor is presented as a non-contact tool for the use in the characterization of thin film hydrogenated amorphous silicon (a-Si:H) photovoltaic cells. The sensor is based on the pump-probe technique and when used...

... of this second round of testing include single-crystalline silicon, polycrystalline silicon, and two thin film materials: tandem-junction amorphous silicon ( 2 - a - Si ) and copper-indium-diselenide (CIS). Two 2 - a - Si panels and two CIS panels were monitored. For each pair of BIPV panels, one was insulated...

One panel of each identical pair is installed with thermal insulation attached to its rear surface. The second paired panel is installed without thermal insulation. This experimental configuration yields...
