Came across an interesting news a month ago:.
IBM has announced that its scientists were able to create a solar cell module, which the core layer, which absorbs most of the light for conversion into electricity, is composed entirely of common and readily available compound of chemical elements. This achievement, which allowed to establish a new world record performance ( efficiency) solar cell, reinforces expectations that the technology of solar electricity has the potential to produce more electricity at lower cost.
A solar cell, which contains copper (Cu), tin (Sn), zinc (Zn), sulfur (S) and / or selenium (Se), demonstrates the efficiency of 9.6 %, which is 40% above the previous rate achieved . In an effort to achieve a breakthrough in the technology of solar cell research, IBM is using its expertise, experience and resources of a world-class in microprocessor technology, materials and manufacturing processes.

IBM scientists describe their achievement in the field of thin-film photovoltaic technology in an article published in the journal Advanced Materials, highlighting the potential of solar energy for the development of cheap electricity on a commercial scale. Developed by researchers photovoltaics also differs from its predecessors is that it was created using a combination of solutions and approaches based on nanoparticles - in contrast to the popular but expensive method of vacuum.
The current thin-film solar cell panel, based on compound semiconductors, demonstrate the efficiency at the level of 9-11%. These elements are most often used two expensive chemical compounds - copper selenide and indium gallium (copper indium gallium selenide) and cadmium telluride (cadmium telluride). As a result, attempts were made to build cheap solar panels on the basis of compounds, including widely distributed on earth chemical elements and do not contain indium, gallium or cadmium, it was not possible to exceed the barrier efficiency of 6.7 % - compared to new record high efficiency in the 9 .
Over the past few years, IBM scientists have achieved a number of important scientific and technological advances associated with the creation of affordable and efficient solar cells. The company has no plans to produce solar panels, but it is open to partnerships with manufacturers of solar cells and is ready to demonstrate their innovative technology.
