  • Effect of seed particle size and ammonia concentration on the growth of ZnO nanowire arrays and their photoconversion efficiency

    ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel coating process. It was found that changing the number of coating process ...

  • Mirrors in Space for Low-Cost Terrestrial Solar Electric Power at Night

    ABSTRACT — A constellation of 18 mirror satellites is proposed in a polar sun synchronous dawn to dusk orbit at an altitude of approximately 1000 km above the earth. Each mirror satellite contains a multitude of 2 axis tracking mirror segments that collectively direct a sun beam down at a target solar electric field site delivering a solar intensity to that terrestrial site equivalent to ...

  • Sunbeams from Space Mirrors in dawn-dusk Polar Orbit feeding Solar fields on the ground for Low Cost Electricity

    A Space Power Satellite capable of providing solar electric power economically for 24 hours per day has been a dream for decades. However, the SPS concept is very complex since it assumes multiple energy conversion steps and includes specially constructed ground microwave receiver stations. The 5 km by 15 km Integrated Symmetric Concentrator SPS concept employs light weight mirrors in a GEO ...

  • Solar powered solid oxide fuel cell with thermoelectric generator

    Durable, location independent, environmental–friendly sources of energy which allow for modular, few moving parts, low operating noise, high electricity generation efficiency and compact technology are highly desirable. Solid oxide fuel cells (SOFCs) are promising for such energy system development, since they are energy efficient and, if pure hydrogen is used, have virtually no emissions of ...

  • Clarification of algae-laden water using electrochemical processes

    Algae contamination of surface water and drinking water supplies is a significant problem particularly in rural areas. A decentralized inexpensive technology that would effectively remove algae from water would be beneficial. Electrocoagulation (EC) combined with electroflotation (EF) as a single process (ECF) is a promising algae harvesting technique with no moving parts that may be powered ...

  • Test Sites And Testing of 3-Sun Mirror Modules

    ABSTRACT The demand for solar photovoltaic cells and modules has far outstripped PV cell supply and module prices are rising. To solve this problem. JX Crystals is developing a 3-sun mirror module that uses 1/3 the cell area to triple module production at a lower cost. Our concentrator module design uses existing planar cells. We simply cut standard SunPower A300 cells into thirds. In ...

  • Water and wastewater treatment for Solar industry

    Solar cells arc manufactured in a complex process thai requires enormous know-how. The objective is to produce panels with a high level of efficiency at low cost. To achieve this, different production processes are used. A fundamental distinction is made between solar cells on the basis of silicon wafers and thin-film cells, in which a special process is used to apply the photovoltaic layer onto ...

  • Renewable Power Generation Costs in 2014

    Executive Summary The competiveness of renewable power generation technologies continued improving in 2013 and 2014. The cost-competitiveness of renewable power generation technologies has reached historic levels. Biomass for power, hydropower, geothermal and onshore wind can all now provide electricity competitively compared to fossil fuel-fired power generation (Figure ES 1). ...

  • Solar fuels: how planes and cars could be powered by the sun

    Solar energy is the world’s most plentiful and ubiquitous energy source, and researchers around the world are pursuing ways to convert sunlight into a useful form. Most people are aware of solar photovoltaics that generate electricity and solar panels that produce hot water. But there is another thrust of solar research: turning sunlight into liquid fuels. Research in solar-derived liquid ...

  • Is Energy Efficiency the correct path to a lower carbon economy?

    European researchers have identified a new “fuel” that by 2030 will be more important than oil. It’s called energy efficiency − the drive to get more bang from each buck spent on power. If the European Union member states adopt a 40% energy efficiency target, the sum of energy ...

  • Why Solar Panels Are Grossly Inefficient (But Sometimes the Only Choice)

    Solar energy is an unlimited power source that, in some ways, is very inefficient. At the moment, developments in photovoltaic (PV) technology cannot meet the expectations of mainstream consumers and commercial establishments. However, this does not mean that solar generators are useless. They play a very crucial role in delivering power to far-flung locations, temporary camps and remote bases. ...

  • We Created the Technosphere, but is it the Birth Place of the Circular Economy

    Human activity has created the ‘technosphere’, a landscape which is composed of the materials we have developed, created and thrown away. Far from being a miserable landscape that may initially come to mind, like the desolate garbage filled scene in WALL-E, it could actually be the basis on which we can create a more sustainable way of managing our resources. Just like we have ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...
