Pure Wafer makes its solar cells from scraps

A UK based silicon wafer recycling company named Pure Wafer has announced that it will start manufacturing high efficiency solar cells from the scrap material it processes.      Pure Wafer’s core business is to help semiconductor manufacturers “gain further efficiencies through the increased re-use of silicon test wafers within their production processes.”   Now Pure Wafer says that it has developed a process to create solar cells out of recycled silicon materials.  The company says that by using scrap silicon left over from the manufacture of semiconductors,  their cells will have a “much lower carbon print than the majority of conventional solar cells available on the market.”

In a statement, the company said: “In order to expedite the move to mass production of its solar offerings, Pure Wafer is prudently investing an initial amount in equipment to manufacture solar panels from its own solar cells thus providing a wholly UK manufactured product.  These products will enable Pure Wafer to offer complete solar systems and solutions to its customers, ranging from single dwellings to large public and commercial buildings.  Pure Wafer has started to receive initial orders for its new products and services, and the level of interest and inquiries are encouraging.”

  1. Ladies and gentlemen, good afternoon. The company Solarus Energy Ltd
    formirut fund $ 3000000 for the completion of work on the production
    technology Solar Cell efficiency of 35%. Support our company, Grant,
    we will finalize our technology, which will reduce the cost of solar
    panel to $ 0.30 per watt. We are ready to take any form of donations
    and investments from organitsatsy and individuals. By combining the
    efforts of many people and organizations we will make. Most of solar
    energy available to the population in the world.

    Our company is interested in quickly attracting venture
    funding to finish work on the technology of production of
    solar modules with high efficiency. request for funding and in the
    annex to the letter the results of our work in the form of a report

    We offer more detailed information on our company and demand for grant
    capital funding in the amount of – $ 3000 000.

    CONSTRUCTION TECHNOLOGY – technology perfected laboratory,
    to manufacture industrial design and conduct an independent test.

    The additional informationFinancing term – 38 months. Return of the
    investor – in the course
    10 days after the expiration of funding.

    PROPOSAL FOR COOPERATION for venture investors
    After production of the industrial design and an independent test, we
    propose % Of revenue from the sale of technology.

    COMMERCIALIZATION developed technology.
    Our technology has a wide range of potential buyers.
    This technology allows all companies to manufacturers of solar modules
    very easy to integrate our technology into an existing, technological
    complex. It is planned to implement the technology on a territorial basis —

    right to the technology will be limited to use by the buyer on the
    and obemu release.

    At present the main trends in development by improving the efficiency of
    photo electric plates in the application of new non-silicon materials.
    So a few days ago, the Japanese company Sharp after 9 years of work
    reported the creation of a prototype battery that runs without a hub, but
    the efficiency of which is 35,8%.
    New uses for electricity generation several photo-absorbing layers, united
    among themselves. The substrate is made of battery connections on the basis
    of indium and gallium. The properties provided by the battery is quite close
    to those used in the aerospace industry. Talking about the mass use will not
    have developers in the coming years to address issues of cost reduction and
    a number of technological problems.
    Our company has gone a different way:
    1. We left a substrate of mono silicon.
    2. on the surface of the substrate of mono silicon, we have consistently
    strike a few
    layers of thickness 50-100 nano meter (materials that are applied is our
    know-how) —
    * Main layer of nano-size mono atomic amorphous silicon, is a very active
    state of amorphous silicon. In this layer, the speed of motion of electrons
    is several times higher than the standard Cell-based silicon. And as this
    layer is able to convert into electrical energy is not only the visible part
    of the spectrum of sunlight and ultra violet and infra red radiation. Mono
    atomic amorphous silicon produced by quantum chemical engineering at a
    temperature of 20 degrees Celsius.
    Properties of mono atomic amorphous silicon are truly unique.
    Cost to automobile 1 gr. This material does not exceed $ 100.
    At the same time using 1 gr. mono amorphous silicon can cover 10 square
    photovoltaic plates.
    * extreme layer is an anti-reflecting the carbon coating.
    Total efficiencies achieved over 35%.
    If you compare the cost of Sell-based mono silicon efficiency 16%
    Cell produced by our technology with efficiency over 35%, our Sell more
    10-15% while the efficiency of our Sell more than 2 times better.
    While improving the technology and equipment we can achieve efficiency of
    50% and above
    The characteristics of our products:
    Dimension :156mm x 156mm ± 0.5mm
    Thickness :203 mc.m ± 0,5 mc.m, 180 mc.m ± 0,5 mc.m
    Front :2.0 ± 0.1mm busbar (silver)
    Silicon nitride antireflection coating
    Back 3.0mm continuous soldering pads (silver)
    Back surface field (aluminum)
    Efficiency – 35%
    Power : 6,5 watt
    Color uniformity A, grade

    In addition to the use of solar energy nanoscale mono atomic amorphous
    silicon and its application of our technology has great prospect of
    application in the electronics industry.
    When applying this material for silicon-based chip, we seek to increase
    speed and memory in the old scale of the chip.
    We have plans to use this technology in other areas – space, medicine ..
    To maintain the pace and timing of the completion of the production of
    industrial prototypes we raise $ 3000 000.

    We are interested in quickly attracting investment.
