Use of Nanotechnology in Solar PV Cell

The solar cell industry has grown quickly in recent years due to strong interest in renewable energy and the problem of global climate change .Cost is an important factor in the success of any solar technology. Todays solar cells are simply not enough efficient and are too expensive to manufacture for large-scale electricity generation. However, potential advancements in nanotechnology may open the door to the production of cheaper and slightly more efficient solar cells. Nanotechnology has already shown huge breakthroughs in the solar field. Quantum dots have the potential to change the world. They are a form of solar cell that is completely beyoznd anything you might imagine. Nanotechnology might be able to increase the efficiency of solar cells, but the most promising application of nanotechnology is the reduction of manufacturing cost. PVs based on CdTe, CuInGaSe (CIGS), CuInSe (CIS), and organic materials are being developed with the aim of reducing the price per watt even if that means sacrificing conversion efficiency and reliability. Utilizing nanotechnology in inexpensive solar cell would help to preserve the environment. Index Terms— Nanotechnology, Quantum dots, Breakthroughs

Statistical analysis of solar-wind-biomass hybrid system installed at R.G.T.U., Bhopal M.P., India.

ABSTRACT This article describes the linkage that exists among the various alternative power sources in the hybrid system. The wind energy system, along with solar photovoltaic panels and a biomass gasifier for the production of electricity, is more suitable among the alternatives available. Wind, solar and biomass energy systems can be used in remote areas. Keeping this in mind, a statistical analysis of the hybrid energy system has been developed for a remote area. Wind and solar data are obtained from a weather monitoring station installed at Energy Park, R.G.T.U., Bhopal, India.

Cost Boundary in Silicon Solar Panel

Photovoltaic is a solar power technology that uses solar cells or solar photovoltaic arrays to convert light directly into electricity with no emission of dangerous gases and with least amount of industrials waste. Solar cells are a key technology in the drive toward cleaner energy production. Unfortunately, solar technology is not yet economically competitive and the cost of solar cells needs to be brought down. Growth of the photovoltaic (PV) market is still constrained by high initial capital costs of PV. One way to overcome this problem is to reduce the amount of expensive semiconductor material used. The materials cost and manufacturing cost of thin-film solar is much lower than wafer based and drops much faster than wafer based in large-scale manufacturing, but thin-film solar cells tend to have lower performance compared with conventional solar cells. Developments in PV technologies may lead to cheaper systems at the likely expense of life expectancy and efficiency. Cost boundaries are required for future PV technologies to compete effectively within the current PV market.[ B. Azzopardi, 1 ].Microand nano-enabled thin-film photovoltaics provide an attractive-and increasingly cost-competitive-clean-tech alternative to carbon-based energy solution.
