In this paper, an optimized method on the basis of polynomial fitting and Lambert W function is presented to extract parameters from the current-voltage (I-V) characteristics of commercial silicon solar cells. Since the experimental outcomes have significant impact on the precision of extracted...

Selective emitter for silicon solar cell was realized by employing a-Si thin films as the semi-transparent diffusion barrier. The a-Si thin films with various thicknesses (∼10–40nm) were deposited by the electron-beam evaporation technique. Emitters with sheet resistances from 37 to...

Well-aligned hierarchical TiO2 tubular macrochannel arrays (HTTMAs) with high surface area have been synthesized via a facile one-step ammonia hydrothermal synthesis process without using any structure-directing templates. The typical samples are made of an assembly of macrochannels with uniform...
