Local photovoltaic characterization for silicon thin film solar cells using a scanning probe microscope

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

Studying of various nanolithography methods by using Scanning Probe Microscope

The Scanning Probe Microscopes (SPMs) based lithographic techniques have been demonstrated as an extremely capable patterning tool. Manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. In this paper, a qualified overview of diverse lithog...

Thin-film crystalline silicon solar cells

A photoelectric conversion efficiency of over 10% has been achieved in thin-film polycrystalline silicon solar cells which consists of a 2 μm thick layer of polycrystalline silicon with a very small grain size (microcrystalline silicon) formed by low-temperature plasma CVD. This has shown that if the recombination velocity at grain boundaries can be made very small, then it is not necessarily i...
