Amorphous Silicon-Carbon Nanostructure Photovoltaic Devices available in PDF, EPUB and Kindle. A novel solar cell architecture made completely from the earth abundant elements silicon and carbon has been developed. Hydrogenated amorphous silicon (aSi:H), rather than crystalline silicon, is used as the active material due to its high absorption through a direct band gap of 1.7eV, well matched to the solar spectrum to ensure the possibility of improved cells in this architecture with higher efficiencies. The cells employ a Schottky barrier design wherein the amorphous silicon absorber layer generates electron-hole pairs from incoming photons and holes are preferentially extracted through a metallic material consisting of a carbon nanostructure. Both graphene and buckypaper were used as the metallic component of the Schottky junction to effectively convert incoming light to electricity. Subsequent work focused on graphene-based cells because graphene offers better transparency and conductance compared to buckypaper, making it promising as a top conductor in a solar cell. Reactions of the graphene-aSi:H interface were investigated and strategies developed to minimize reactions that lead to performance degradation. Finally, photon management strategies were executed to significantly enhance the performance of the cells using silver nanoparticles to increase the absorbance of light and extraction of charges in a thin aSi:H film. Solar cells optimized with these improvements show performance enhancements of 1-2 orders of magnitude compared to initially published cells in this architecture. In addition to yielding strategies for improved protection and performance of the solar cells presented in this thesis, investigations presented here into reactions at the graphene-silicon interface should inform further research into applications of graphene.

Schropp. This book was released on 2016-07-18. Amorphous and Microcrystalline Silicon Solar Cells: Modeling, Materials and Device Technology available in PDF, EPUB and Kindle. Amorphous silicon solar cell technology has evolved considerably since the first amorphous silicon solar cells were made at RCA Laboratories in 1974. Scien tists working in a number of laboratories worldwide have developed improved alloys based on hydrogenated amorphous silicon and microcrystalline silicon. Other scientists have developed new methods for growing these thin films while yet others have developed new photovoltaic (PV) device structures with im proved conversion efficiencies. In the last two years, several companies have constructed multi-megawatt manufacturing plants that can produce large-area, multijunction amorphous silicon PV modules. A growing number of people be lieve that thin-film photovoltaics will be integrated into buildings on a large scale in the next few decades and will be able to make a major contribution to the world's energy needs. In this book, Ruud E. I. Schropp and Miro Zeman provide an authoritative overview of the current status of thin film solar cells based on amorphous and microcrystalline silicon. They review the significant developments that have occurred during the evolution of the technology and also discuss the most im portant recent innovations in the deposition of the materials, the understanding of the physics, and the fabrication and modeling of the devices.
