High Efficiency Solar Cell breakthrough

From KeelyNet News: In a scientific breakthrough that has stunned the world, a team of
South African scientists has developed a revolutionary new, highly
efficient solar power technology that will enable homes to obtain all
their electricity from the sun. The unique South African-developed
solar panels will make it possible for houses to become completely
self-sufficient for energy supplies. The panels are able to generate
enough energy to run stoves, geysers, lights, TVs, fridges, computers -
in short all the mod-cons of the modern house.
The new technology should be available in South Africa within a year and through a special converter, energy can be fed directly into the wiring of existing houses. New powerful storage units will allow energy storage to meet demands even in winter. The panels are so efficient they can operate through a Cape Town winter. while direct sunlight is ideal for high-energy generation, other daytime light also generates energy via the panels. A team of scientists led by University of Johannesburg (formerly Rand Afrikaans University) scientist Professor Vivian Alberts achieved the breakthrough after 10 years of research. The South African technology has now been patented across the world. International experts have admitted that nothing else comes close to the effectiveness of the South African invention. The South African solar panels consist of a thin layer of a unique metal alloy that converts light into energy. The photo-responsive alloy can operate on virtually all flexible surfaces, which means it could in future find a host of other applications. Alberts said the new panels are approximately five microns thick (a human hair is 20 microns thick) while the older silicon panels are 350 microns thick. the cost of the South African technology is a fraction of the less effective silicone solar panels.

As Much Hot Water As Your Need Or The Sun In Trap
A unique solar collector was developed by specialists of the Moscow “ALTEN” company under the guidance of Boris Kazandzhan, Professor, Doctor of Science (Engineering), Moscow Power Engineering Institute. Originality of the novelty lies in its extremely high efficiency. The collector not only manages to entrap the heat of solar beams falling on its surface, but also to utilize it to a great extent for direct purpose – for water heating.
