Optical materials technology for energy efficiency and solar energy conversion XII
- ed.; Lawrence Berkeley Lab., CA (United States). Energy and Environment Div.
Currently, there is an upswing in solar and energy conservation activities due to increased awareness of environmental degradation and limited resources. A technology area that continues to grow is that of transparent window materials for the control and modification of radiant energy transport. There has been rapid deployment of many new window coatings into the building glazing industry, and specialized glazing coatings are also expected to impact the automotive industry in the near future. Many of the papers presented at the conference contained information on chromogenic, or smart, window devices for architectural and automotive glazing. Unifying work on the chemistry of electrochromic oxide was discussed, and there were several papers on electrochromics, including advances on polymer ion storage layers, tungsten oxide, nickel oxide, and copper oxide. Another area of continued research is in photovoltaics, photochemistry, and photoelectrochemistry. Significant work on the titanium oxide-dye sensitized nanocells was presented. This is a new type of very low cost solar cell with 8--12% efficiency. Still other papers dealt with developments in diffractive, holography, and holographic concentrators for solar and daylight applications. A trend here is to go to larger-size parabolic collectors, lower cost, and higher operating temperatures. The higher operating temperatures create challenges for the selective surface designer. Advances in absorbers include new types of metal oxynitride and metal cermet absorbers. Separate abstracts were prepared for 37 papers in this volume.
