Selection of potential supplier is a strategic decision taken by purchasing department which helps in ensuring a long term commitment between supplier and industry. Selection of supplier is a multi criteria decision making (MCDM) problem involving quantitative, qualitative, tangible and non tangible diverse criteria's. In this work a strategic frame work has been proposed which allows decision makers...
Global use of solar energy and wind energy will provide clean energy for sustainable global economic growth. The use of photovoltaic systems for DC power generation and the delivery and the utilization of DC power will bring revolution in energy field by providing ultra-low-cost clean energy to rich and poor all over the world. Ultra large scale manufacturing of PV modules coupled with wide band gap...
Photovoltaics (PV) offer a unique opportunity to solve the 21st century's electricity generation problem because solar energy is essentially unlimited and PV systems provide electricity without any undesirable impact on the environment. With current technology of silicon based PV systems, volume manufacturing, appropriate business model and without any subsidy, PV electricity can be generated today...
We present high-resolution thermal images of the electrical contacts inside an active thermoelectric micromodule that are acquired through the silicon substrate using near-infrared thermoreflectance. The temperature distribution of the contacts induced by the Peltier and Joule effects are separated. This technique can be utilized as a nondestructive means to evaluate metallization and contact resistance...
Rising demands of energy in emerging economies coupled with the green house gas emissions related problems around the globe have provided a unique opportunity of exploiting the advantages offered by solid state devices (photovoltaic devices, thermoelectric devices, light emitting devices etc.) for green energy conversion. Similar to cell phones, power generation by photovoltaics (PV) can reach over...
