In addition, the report discusses the major drivers that influence the growth of the Smart Grid market in China. It also outlines the challenges faced by the vendors and the market at large, as well as the key trends that are emerging in the market.

Large and advanced batteries are those batteries which are rechargeable and technologically advanced; these batteries are large in size and energy capacity. The advanced batteries are largely used in plug-in vehicles, utility load leveling systems, and renewable energy storage systems. The increased usage of these batteries in the Automotive segment and the Portable Electronic Products segment is one of the major factors driving the growth of the Global Large and Advance Battery Technology market.

A Li-ion battery is a rechargeable battery where lithium ions move from the negative electrode to the positive electrode during discharging and back when charging. There are numerous advantages of using lithium as it is one of the lightest metals. Li-ion batteries are commonly used in the Consumer Electronics sector, the Industrial sector, and the Automotive sector.

Light trapping in solar cells allows for increased efficiency and reduced materials cost. It is well known that a 4n^2 factor of enhancement in absorption can be achieved by randomly texturing the surface of the solar cell, where n is the refractive index of the material. However, this limit only holds when the thickness of the solar cell is much greater than the wavelength of light. In the subwavelength regime, the fundamental question remains unanswered: what surface texture realizes the optimal absorption enhancement? We turn to computational inverse electromagnetic design in order to find nanoscale textures for light trapping, and observe spontaneous symmetry breaking in the creation of optimal design.

In this report, we reviewed the requirements and challenges of performing spectrum sensing in the TV band for mobile applications. We described the existing state of this area of research from both a technical and a policy perspective, and reviewed existing theoretical techniques for performing signal detection. We then proposed a novel physical implementation of a spectrum sensing system by using subsampling autocorrelation in the analog domain.

To address these issues, this work proposes a novel, plug-through power monitoring system for commercial and residential use. Our device detects any appliance’s power consumption via a current sense transformer, which wirelessly couples magnetic energy from the appliance to output an electromotive force voltage.

A combination of rising energy costs, a desire for national energy independence, and a growing awareness of the dangers of global climate change is pushing Americans to do what they can to save energy. Consumers now buy more fuel-efficient cars and appliances and are growing more aware of their use habits. While it is easy to see how much gas your car uses, beyond the labeling on major appliances at the point of sale, most consumers are unaware of how much electricity these devices actually use. In this Masters of Engineering Capstone Project we designed and implemented a wireless power monitor which sits on a conventional power outlet and is thin enough that an appliance plugs throughs. The power of the appliance being plugged through our device is monitored. The monitor is powered by either making direct contact with the prongs of the plug or by inductively harvesting through a contactless transformer. The latter case puts severe power restrictions on the mote which we overcame by using low-power hardware and OpenWSN, a network stack intended for low power, low data-rate applications such as ours.

This paper discusses basic concepts of color science and color rendering. Different methods of measuring color rendering and the new standard under development by the International Illumination Committee and several industry leading companies are introduced. Furthermore, the current situation of the LED market and the different roles of leading companies are discussed. Finally, a forecast of the future of LED and its market pattern will be given based on an analysis of the market.

Photonic innovation is becoming ever more important in the modern world. Optical systems are dominating shorter and shorter communications distances, LED's are rapidly emerging for a variety of applications, and solar cells show potential to be a mainstream technology in the energy space. The need for novel, energy-efficient photonic and optoelectronic devices will only increase. This work unites fundamental physics and a novel computational inversedesign approach towards such innovation.

Light emitting diode (LED) technologies present significant advantages compared to today’s lighting solutions: LEDs are favorable in terms of their electrical efficiency, economical value, and environmental impact. The question remains, when, if at all, will these technologies replace all the light bulbs and tubes in the world? We addressed this question by surveying both the technology and market landscape for solid state lighting. We found that solid state lighting technologies will become the dominant lighting solution within several years, as they steadily improve in color quality, brightness, and cost, and receive support from environmental and political policies.

This report focuses on the analysis of light emitting diode (LED) technology in the olid state lighting (SSL) market, that is, whether or not LED lighting products will eplace incandescent bulbs and compact fluorescent lamps (CFLs).

To summarize, the goals of this thesis were to motivate analog synthesis by showing some examples of fully automatic generators and (2) to create a code framework for fully automatic standard cells that could be extended to other styles of layout.
