What are the advantages of biomass electricity?

Today we live in the world which is rapidly changing and moving fast. The speed at which we are affecting our ozone layer is very fast, as we can imagine how the weather conditions use to be 20 years back and now how the weather is changing. The glaciers are also melting at a fast rate and this is now creating many problems for the people. We must act fast and switch to environmental friendly products. Environmental friendly products do not harm the ozone layer and this is one of the main advantages of biomass energy. Biomass energy is the best alternative source for producing electricity, fuels and other in other form of industries.
Biomass is …

Effective solar cells and sensitive bioanalysis

The efficiency factor of solar cells is crucial for the success of generating electricity from sunlight. Systems in which light is concentrated 400-fold through lenses onto solar cells are proving to be particularly advantageous.
This concentrator technology enables expensive semi-conductor material to be replaced with cheaper lens systems, and greater efficiency to be achieved. In his thesis, physicist Marc Steiner from the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg presented a way of increasing the efficiency of these concentrator solar cells even more.
The contacting of the semi-conductor layers plays a crucial role here, and Marc Steiner’s new simulation program optimizes the structure and configuration of the metallic contact fingers. These calculations yielded unprecedented efficiency …
