Fullerene Crystalline Thin Film Semiconductor.

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...

Metal-Semiconductor Interfaces in Thin-Film Transistors

The metal-semiconductor interface in thin-film transistors (TFTs) is one of the bottlenecks on the development of these devices. Although this interface does not play an active role in the transistor operation, a low-quality interface can be responsible for a low performance operation. In a-Si TFTs, a doped film can be used to improve this interface, however, in other TFT technologies, there is...

Photonic Systems for Crystalline Silicon and Thin-Film Photovoltaic Manufacturing

In this chapter, we will discuss the impact that photonics have on photovoltaic (PV) manufacturing. The broad field of photonics is now commonly thought to encompass classical optics (Hecht, 2001), nanophotonics (Joannopoulos et al., 2007), and metamaterials (Cai and Shalaev, 2009). Over the last few decades, photonic technology has become an increasingly integral part of PV manufacturing, both...

Amorphous-to-crystalline phase transformation of thin film rubrene.

We report on the amorphous-to-crystalline phase transformation of rubrene thin films. The crystallization of the organic thin films displays disk-like domains whose nucleation and growth follow phase transformation kinetics well-established for inorganic materials under certain time and temperature conditions. We understood that the crystallization of amorphous rubrene thin film shows site-satu...
