Download or read book Diffractive Optics for Thin-Film Silicon Solar Cells written by Christian Stefano Schuster and published by Springer. This book was released on 2016-09-26 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis introduces a figure of merit for light trapping with photonic nanostructures and shows how different light trapping methods compare, irrespective of material, absorber thickness or type of nanostructure. It provides an overview of the essential aspects of light trapping, offering a solid basis for future designs. Light trapping with photonic nanostructures is a powerful method of increasing the absorption in thin film solar cells. Many light trapping methods have been studied, but to date there has been no comprehensive figure of merit to compare these different methods quantitatively. This comparison allows us to establish important design rules for highly performing structures; one such rule is the structuring of the absorber layer from both sides, for which the authors introduce a novel and simple layer-transfer technique. A closely related issue is the question of plasmonic vs. dielectric nanostructures; the authors present an experimental demonstration, aided by a detailed theoretical assessment, highlighting the importance of considering the multipass nature of light trapping in a thin film, which is an essential effect that has been neglected in previous work and which allows us to quantify the parasitic losses.
Book Synopsis Silicon Based Thin Film Solar Cells by : Roberto Murri
Download or read book Silicon Based Thin Film Solar Cells written by Roberto Murri and published by Bentham Science Publishers. This book was released on 2013-03-20 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon Based Thin Film Solar Cells explains concepts related to technologies for silicon (Si) based photovoltaic applications. Topics in this book focus on ‘new concept’ solar cells. These kinds of cells can make photovoltaic power production an economically viable option in comparison to the bulk crystalline semiconductor technology industry. A transition from bulk crystalline Si solar cells toward thin-film technologies reduces usage of active material and introduces new concepts based on nanotechnologies. Despite its importance, the scientific development and understanding of new solar cells is not very advanced, and educational resources for specialized engineers and scientists are required. This textbook presents the fundamental scientific aspects of Si thin films growth technology, together with a clear understanding of the properties of the material and how this is employed in new generation photovoltaic solar cells. The textbook is a valuable resource for graduate students working on their theses, young researchers and all people approaching problems and fundamental aspects of advanced photovoltaic conversion.

Book Synopsis Design and Fabrication of Photonic Crystals and Diffraction Gratings for Ultra Thin Film Si Solar Cells by : Xianqin Meng
Download or read book Design and Fabrication of Photonic Crystals and Diffraction Gratings for Ultra Thin Film Si Solar Cells written by Xianqin Meng and published by . This book was released on 2012 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gratings are considered. The goal is to integrate such structures into ultra-thin film silicon photovoltaic solar cells, with a view to improve their conversion efficiency. First, a PCs assisted ultra-thin film crystalline silicon (c-Si) solar cell is designed optimized by using the Finite Different Time Domain (FDTD) approach. An increase over50% is achieved for the absorption, as integrated over the whole spectral range, by patterning a 2D PCs in the active Si layer. This enhancement is achieved by combining Slow Bloch modes and Fabry-Perot modes. In order to fabricate such solar cells, we developed a process based on Laser Holographic Lithography, Reactive Ion Etching and Inductivity Coupled Plasma etching. We have investigated the influence of the parameters taking part in these processes on the obtained patterns. Finally the optical and electrical properties of the devices have been characterized by our co-workers at IMEC, Belgium. Absorption measurements are in good agreement with the theoretical simulations. Moreover, the integrated absorption is tolerant with regard to the sunlight angle of incidence. The final fabricated 2D PCs patterned solar cell exhibits a 20% higher short circuit current (Jsc = 15mA/cm2) than the reference. Additionally, a more complex thin film c-Si solar cells integrating front and back diffraction gratings has been designed. Long wavelength absorption is increased thanks to the long period (750 nm) back grating, while the incident light reflection is reduced by using a short period (250 nm) front grating. A short-circuit current increase up to 30 mA/cm2 is predicted for this device, far above the 18 mA/cm2 value for the unpatterned reference These are first steps towards the development of a future generation of PC and diffraction grating assisted solar cells.
