Silicon Solar Cell Efficiency Improvement Through Advanced Cleaning Technology

Bohling D.A., Goldstein A., Treichel H., Lizard T., George M.A., Sunsonix, US

Sunsonix™ has identified a technology gap/need in the area of crystalline silicon photovoltaic efficiency and field degradation. The cause of both poor efficiency and rapid degradation may share common roots, that being trace contamination at [...]

Improve of Photovoltaic Performance of Dye-sensitized Solar Cell by Concentrating Solar Energy

Kim Y-W., Cho E., Choi S.C., Choi S.C., Lee D.W., Pusan National University, KR

Dye-sensitized solar cell (DSSC) is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture against the silicon solar cell. Accordingly, the DSSC is constantly researched globally. One [...]

Growth of improved ultrathin pristine SnO2 films by electric field modified spray pyrolysis technique

Shikha S., Pandya D.K., Kashyap S.C., Chaudhary S., IIT Delhi, IN

In the present paper, deposition of good quality polycrystalline pristine SnO2 thin films (25-200 nm) at ~ 450C by a modified spray pyrolysis technique is reported.DC electric field is applied during deposition to improve growth [...]

Combining solution processed and vacuum deposited layers in small molecule organic solar cell

Kim Y., Imperial College, UK

In this work the characteristics and mechanisms remarkably affecting efficiency in vacuum deposited small molecule solar cells using pentacene, C60, and BCP and the combination of solution processed and vacuum deposited layers like a P3HT [...]

An Ab Initio Study of CuGaSe2 (001) Surface

Chew S., Liborio L., Harrison N., Imperial College London, UK

The chalcopyrite material CuIn1-xGaxSe2 makes one of the best performing devices for thin film solar cells. Despite this, there is still a lack of understanding of some of the fundamental properties of the material. CuGaSe2 [...]

Generation of Transportation Fuel from Solid Municipal Waste Plastics

Sarker M., Natural State Research, Inc., US

Transportation fuels derived from imported fossil fuels are subjected to the price fluctuations of the global marketplace, and constitute a major expense in the operation of a vehicle. Emissions from the evaporation and combustion of [...]

Diesel Production from Waste Disposal using Catalytic Dissociation on Mn-zeolite Catalyst

Kim M.C., Lee K.B., Cheongju University, KR

The approach for catalytic dissociation of waste diaposal using various catalysts is presented. This approach includes two principal steps: a characterization of catalysts is used to determine the active site of prepared catalysts, and the [...]

New Kalina Cycle Systems for Biomass Applications

Kalina A., KALEX LLC, US

Three new Kalina Cycle power systems have designed for the utilization of biomass fuel. These systems offer drastic improvements in efficiency, (on the order of 40% to 60%,) and reduction in cost over current conventional [...]

Replacing natural gas with biogas in the methanol production

Kovac Kralj A., Univerity of Maribor, SI

The dependence of natural gas may be replaced by renewable sources of second generation - nonfood source. Methanol is produced from synthesis gas, which is produced from natural gas. Natural gas can be replaced by [...]

Development of ceramic support for methane reformer from alkali aluminosilicates

Martinello Savi B., Fernandes Silvano W., da Silva L., Bernardin A.M., University of the Extreme South of Santa Catarina, BR

This work deals with the initial development of a ceramic reformer based on alkali metal aluminosilicates coated with nickel for the generation of hydrogen from biogas (methane). The understanding of the microstructural evolution of silicon-aluminum [...]
