New Solar Cell Technologies That Lower Costs And Raise Outputs May Help Bring Electricity To The Wor

New technologies reveal the possibility of new solar cells being developed commercially

with higher conversion efficiencies than those now available, is shown in a recent UK study.

With reasonable energy provision remaining one of the planet's most insistent wants, the advances being made in this area offer real hope for a future in which energy supplies are rather more generally available without the obstacle of environmental damage.

From one perspective the third world wants a tremendous increase to access of affordable energy because; at the moment 1.6 billion people in the planet's poorest nations don't have a power supply.

These people present a huge future demand for access to affordable energy.

Therefore supportable development is threatened by a 'double whammy':

Now sustainable development is in danger for a couple of reasons.

2 things currently happening are threatening sustainable development around the world.

* The providing systems are often previously environmentally damaged.

* Environmental damage to the providing systems is frequent.

The world's energy wants are unlikely to be solved by a single solution resulting from the many complications of this issue.

* It is doubtful that energy suppliers will ever use wind or solar as a stand alone system because these systems are often intermittent.

If systems aren't cheap they are going to be outside the reach of the poorer nations whose needs are most pressing.

The poor nations whose needs are the greatest will find these systems out of reach if they are costly.

High cost will keep these systems out of reach to the poorer nations whose needs are the greatest.

The technology until recently has been curbed by the comparatively high costs concerned. Now the Sheffield Hallam School team from the UK has come up with some cost-cutting ideas:

Now the Sheffield Hallam School team out of the UK has been using some new technologies which have lowered cost and increased electrical output. They put into play some cost-cutting ideas;

* Electro deposition being a low cost manufacturing technique has less dependence on expensive semi-conductor materials.

* Electro deposition is a low cost semiconductor technique that uses less dependence on expensive semiconductor material.

The study initiative of, Cheap , High-efficiency Thin-film Solar cells with Electro deposited Semiconductors, has received first total Engineering and Physical Sciences Research Council funding of over $100,000 and follow-up from Sheffield Hallam School of over $200,000.

EPSRC Engineering and Physical Sciences Research Council is the UK's main agency for funding research in engineering and the physical sciences and invests more than $600 million per year in research and postgraduate coaching to help the country handle the new generation of technical change.

2 distinct systems now entering the PV market are based primarily on the utilization of cadmium telluride ( CdTe ) and copper indium gallium di-selenide ( CIGS ) materials in solar cells.

The team at Sheffield Hallam Varsity has increased our knowledge of PV by illustrating how solar cells based mostly on CdTe and CIGS structures work.

Shortage of PV knowledge along with high costs has been an impediment to the wide spread use of the technology.The Sheffield Hallam University has increased the knowledge of how (CdTe) and (CIGS) work within solar cells.
