is there any substitute for silicon in the production Solar Cells?

the most promising alternative is known as organic photovoltaic, based on organic molecules/dyes

http://en.wikipedia.org/wiki/Organic_solar_cells

while not as efficient as silicon in W/m2 they will be cheaper and easier to manufacture. so they are a good option if space and weight are not an issue

Solar Shingles $90.81 High Quality Content by WIKIPEDIA articles Solar shingles, also called photovoltaic shingles, are photovoltaic cells designed to look like conventional asphalt shingles. There are several varieties of solar shingles, including shinglesized solid panels that take the place of a number of conventional shingles in a strip, semirigid designs containing several silicon solar cells that are sized more like conventional shingles, and newer systems using various thin film solar cell technologies that match conventional shingles both in size and flexibility. Solar shingles are manufactured by companies including SunPower Corporation, Solar Components Corporation, Atlantis Energy Systems, and Dow Chemical.

Manifold Microchannel Cooling of Photovoltaic Cells $111.53 Several works have been published on concentration of solar radiation by mirrors or lenses onto smaller size solar panels, which reduce cost and increase conversion efficiency at higher concentration ratio. One of the challenges is active and uniform cooling of high heat flux solar arrays, because conversion efficiency is dependent on device temperatures and drops with increasing temperature. This research is targeted at cooling of small, high concentrated solar cells. Benefits of manifold microchannel are attractive for cooling of electronic devices but have not been studied for cooling of high concentrated solar cells which is the objective of this research, where the microchannel can be microfabricated and etched on the backside of the silicon solar cell to form a sealed heat sink with the manifold fabricated in the silicon substrate. This design not only minimizes the pressure drop, but also maximizes the heat transfer and provides uniform temperature across the device.

NonUniformities in ThinFilm Solar Cells and Modules $157.72 Thinfilm PV technology due to its fast production line, large area panels and low material usage, is one of the most promising lowcost technologies. Due to their granular structure, thinfilm solar cells are inherently nonuniform. Fluctuations inevitably occur during the multistep deposition process of large area thinfilm solar panels and specific manufacturing procedures. Furthermore, non uniformities can become more severe, or increase in size during the solarpanels life cycle. Non uniformities reduce the overall efficiency of solar cells and modules, and their effects therefore need to be well understood. This manuscript focuses on the analysis of the effect of nonuniformities on small size solar cells and modules with the help of numerical simulations. Even though the 2D model developed here can analyze the effect of nonuniformities of any nature, only two specific types of microscopic nonuniformities were addressed here: shunts and weakdiodes. One type of macroscopic nonuniformity, partial shading, was also addressed. The circuit model developed here is a network of diodes, currentsources, and transparentconductiveoxide resistors.

Solar Silicon Refining by Ciftja, Arjan [Paperback] $130.64 The main objective of the present work is the removal of inclusions from silicon scrap and metallurgical grade silicon. To reach this goal, two various routes are investigated. First, settling of SiC particles from molten silicon followed by directional solidification is reported in this book. Then, removal of SiC and Si3N4 inclusions in silicon scrap by filtration with foam filters and wettabilities of silicon on graphite materials are studied. To supply the increasing needs of the PV industry it is necessary to produce a low cost silicon feedstock. The high carbon content of the metallurgical grade silicon in the form of SiC particles, needs to be removed before the silicon could be used as a feedstock to PV industry. The difference in density between the particles and the melt gives the SiC particles a relatively high settling velocity leading to a high removal efficiency. However, higher removal efficiencies are required. Filtration with foam filters appears to be very efficient and the removal efficiency for a 30 ppi SiC filter is more than 99. A new filtration model named branch model is developed in this work.
