Bluenergy overlapping cell connection (patents pending)

RIGHT: Bluenergy pv-element for the production of overlapping modules
Heart and soul of the Photovoltaic are photosensitive, mono or polycrystalline silicon semiconductors.To be able to retrieve the energy, connections are necessary which are normally visible as soldering strips on the surface. Not so with Bluenergy.
Bluenergy has developed a method, which makes possible to overlap the contact tracks with the semiconductor elements.
This may not sound exciting, but the advantages are convincing: besides an aesthetic optics and an optimal use of the surface,it is avoided that soldering fat causes corrosion, which can destroy the modules on a long-term basis. In addition it saves steps in production, which simplifies the production procedure, and thus increases productivity.
Altogether a revolution for the PV-market.
Bluenergy anti reflecting foil, stain resistant, self cleaning (patents pending)
The Dendrite structure in the nanometer range prevents reflections and improves the dirt-deflecting characteristics of Fluor polymer.
Reflecting surfaces and surface contamination have an unwanted effectfor the Photovoltaic: valuable light is lost for power production.
A glass pane behaves like a water surface.The lower the angle of the radiation, the more light is reflected; under an angle of 45 degrees appr. completely. Since the sun cannot be fixed to one point, and it is not always possible to optimize the alignment of the solar panels (not every roof area points to the south), Bluenergy has developed a polymer foil, made with a micro structure that catches the incident light from all angles, and is self-cleaning (Lotus flower effect). All Bluenergy products have these specifications.
This is an essential and unique advantage, because conventional cells need to be cleaned on a yearly basis in order to maintain the efficiency.This complex and expensive procedure is avoided with the Bluenergy modules.
The electrification of the Transrapid train with solar energy was a task, which represented a large challenge.
Conventional photovoltaic modules with a glass body could not withstand the enormous over and under pressure produced by the over 400 km/h trains. For this and other applications, Bluenergy has developed a completely new module, whose carrier is made from a perforated, stainless high-grade steel plate (V2A sheet metal) - practically indestructible, and once again - unique in the world.The developed procedure can be applied to many other materials i.e. plastics.
This opens completely new application possibilities for further product groups such as Carports for solar cars, power supply for ships etc.
Bluenergy Flexible Membrane-Module
What recently seemed technically impossible, is with Bluenergy soon to be produced:
The combination of flexible materials with Photovoltaic modules.
The proprietary encapsulation (Teflon), which is common in all Bluenergy products, is also used for this application.This allows the use of photovoltaic for all kinds of tents or awnings made from fibreglass or Trevira. In addition, these materials are flame resistant.
Areas of application are for example: Sail boats, which would get their power requirement directly from their own sails, tents, as well as all surfaces, which are subjected to twisting forces, which would destroy conventional solar modules, or which could not statically carry heavy conventional pv-modules.
