Abstract

The basis of this method is the production of different glass structures in a delimited space, within a glass body, with different geometrical embodiments of these altered glass regions, by locally delimited heating of the glass body, by means of laser beams. The locally heated glass regions, by means of various lasers, alter the structure of the glass region present and thus create the conditions for a desired and targeted reflection at the contact areas/volume between the unaltered and the molten glass regions. Said reflection is influenced by the position of the molten and reestablished regions in the glass body such that the continuation of the refracted light beams through the entire glass body to a combination/amplification of the light in well-defined zones of the glass body is achieved and the reflected light beam can be coupled out here. By virtue of the implementation of a well-calculated light course in the glass body and the associated design/positioning of the reflectors, it is also possible to achieve a focusing point, outside the glass body, for the reflected light beams. In the implementation of this method, it is possible to achieve a significantly higher energy density per unit area than that possible as a result of the solar energy present. As a result of this higher energy density, higher electricity generation can then also be achieved by means of such altered solar cells.

Reflektoren im Glas Beschreibung  Reflectors in glass description
Das Patent bezieht sich auf die Realisierung einer im Glaskörper (beliebiger räumlicher Ausdehnung), mittels Lasertechnik oder The patent relates to the realization of a glass body (arbitrary spatial extent), using laser technology or
anderer Technologien, an einem bestimmten Punkt/Raum (im Glaskörper) und in einem definierten Winkel, eingebrachten Materialveränderung, eine begrenzte, geometrische Verformung, durch eine begrenzte lokale Erwärmung zu erreichen. other technologies, at a certain point / space (in the glass body) and at a defined angle, introduced material change, a limited, geometric deformation to achieve by a limited local heating.
Durch diese Materialveränderung entsteht ein Übergang zwischen zwei Glas-Medien (unterschiedliche This material change creates a transition between two glass media (different
Glasstrukturen- neue Oberfläche) die zur Lichtbrechung bzw. Reflektion führen. Glass structures - new surface) which lead to refraction of light or reflection.
Hier wird künstlich eine Grenzfläche geschaffen, welche als Reflexionsfläche/-volumen genutzt werden kann.  Here, an interface is created artificially, which can be used as a reflection surface / volume.
Durch eine wohldimensionierte, berechnete Temperatureinwirkung in einem berechneten Raum, wird die vorhandene Glasstruktur so verändert, dass eine Grenzfläche/Grenzraum gebildet wird, der den Gesetzen der optischen Reflektion folgt, (siehe /l/ )  By a well-calculated, calculated temperature effect in a calculated space, the existing glass structure is changed so that an interface / boundary space is formed, which follows the laws of optical reflection, (see / l /)
Durch eine zielgerichtete Positionierung des veränderten Glasbereiches (Grenzfläche/Grenzraum) kann eine Reflektion des auftreffenden Lichtstrahls erreicht werden, so dass der reflektierte Lichtstrahl, durch die Lage der Reflektoren im Glaskörper, in eine gewünschte Richtung gelenkt werden kann, (siehe Skizzel.a/l.b/l.c)  By a targeted positioning of the changed glass area (interface / border area) a reflection of the impinging light beam can be achieved, so that the reflected light beam, by the position of the reflectors in the glass body, can be directed in a desired direction (see Skizzel.a / lb / lc)
Durch eine entsprechende Verkettung mehrerer Reflektoren (räumliche Gestaltung und Lage im Glaskörper) kann der Lichtstrahl zu einem gewünschten Austrittspunkt am Glaskörper geführt werden. Werden somit mehrere Lichtstrahlen zu einem wohl definierten Austrittspunkt geführt, so kann an dieser Stelle, eine (entsprechend der Anzahl der Lichtstrahlen, Strahlenbündel) definiert, verstärkte, Lichtauskopplung erfolgen.  By appropriate concatenation of multiple reflectors (spatial design and position in the glass body), the light beam can be guided to a desired exit point on the glass body. Thus, if a plurality of light beams are guided to a well-defined exit point, at this point, one (corresponding to the number of light beams, bundles of beams) defined, amplified, light extraction can take place.
Die Einbringung der Reflektoren kann an jedem Punkt des Glaskörpers und in einer zuvor berechneten Anzahl erfolgen.  The introduction of the reflectors can be made at any point of the glass body and in a previously calculated number.
Diese gewollte Führung und damit einhergehende Verstärkung des Lichts hat zur Folge, dass z.B. bei der Solarzellenherstellung (Photovoltaik) weniger und zielgerichteter, Halbleitermaterial eingesetzt werden ,kann um eine Erhöhung der direkten Stromproduktion der Solarzelle (bei gleichem oder geringeren Materialeinsatz) erreicht werden kann. Die Dimensionierung der Größe und der Lage des Reflektors im Glas, ist abhängig von der benutzten Schmelz- Beschussenergie des Einbringungsmediums (Lasertechnik etc.). (siehe /l/) This deliberate guidance and concomitant amplification of light has the consequence that, for example, less and more targeted, semiconductor material can be used in solar cell production (photovoltaics) can be achieved by increasing the direct power production of the solar cell (with the same or lower material use). The dimensioning of the size and the position of the reflector in the glass depends on the used melting energy of the injection medium (laser technology etc.). (see / l /)
Der kleinste Radius eines Reflektors im Glas, sollte die Wellenlänge des zu benutzenden Lichtes nicht unterschreiten. Nach oben sind die Abmessungen nur durch die Stabilität des Glaskörpers (Rissfestigkeit) und der Schmelz-/Beschusstechnik begrenzt. Hierbei spielt die Rissfestigkeit des Glaskörpers eine maßgebliche Rolle, (siehe /l/) The smallest radius of a reflector in the glass, should not fall below the wavelength of the light to be used. Upwards, the dimensions are limited only by the stability of the glass body (crack resistance) and the melting / Beschusstechnik. Here, the crack resistance of the glass body plays a significant role, (see / l /)
Durch die Ionisierung bzw. Erzeugung einer Schmelze des im Focus des Laserstrahls befindlichen Glaskörpers, wird ein Bereich erzeugt, der eine eigene Oberfläche im Glaskörper erhält und damit Reflektionen des Lichtes zulässt. By the ionization or generation of a melt of the glass body located in the focus of the laser beam, an area is created which receives its own surface in the glass body and thus permits reflections of the light.
Durch die Lage, der im Glaskörper veränderten Volumenelement (Reflektoren)  Due to the position of the volume element changed in the vitreous (reflectors)
wird ein vorher berechneter Lichtweg im Glas durch den einfallenden Lichtstrahl durchlaufen und kann durch Zusammenführung mehrerer reflektierter Lichtstrahlen verstärkt werden und zu einem ganz bestimmten, berechneten Austrittspunkt geführt werden. (Skizze 2.a/2.b/2.c/2.d/2.eund Skizze 3) Die zum jeweiligen Austrittspunkt geführte Lichtenergie (Intensität) kann durch vorhergehende a previously calculated light path in the glass is traversed by the incident light beam and can be amplified by combining a plurality of reflected light beams and guided to a specific, calculated exit point. (Sketch 2.a / 2.b / 2.c / 2.d / 2.eand Sketch 3) The light energy (intensity) guided to the respective exit point can be determined by preceding
Berechnungen und daraus folgend die Berechnung der Reflektoren im Glaskörper zielgerichtet bestimmt werden. Calculations and, consequently, the calculation of the reflectors in the vitreous targeted.
Durch die Wahl der Austrittspunkte in Kombination mit der Lage der Reflektoren kann auch der mögliche Licht-Fokussierungspunkt außerhalb des Glaskörpers liegen.  By choosing the exit points in combination with the position of the reflectors, the possible light focusing point can also be outside the glass body.
Eine Veränderung des Glaskörpers wird bei der Erstellung der Reflektoren, nur im Fokus des Laserstrahls vollzogen und damit wird keine Veränderung außerhalb dieses Bereiches erfolgen.  A change of the glass body is accomplished in the creation of the reflectors, only in the focus of the laser beam and thus no change outside of this range will take place.
Durch die zielgerichtete Einbringung der Reflektoren im Glaskörper kann ein gebündelter und damit verstärkter Lichtstrahl, auch an den Seitenrändern des Glaskörpers, einen Austrittspunkt bzw. Due to the targeted introduction of the reflectors in the glass body can be a focused and thus amplified light beam, even at the side edges of the glass body, an exit point or
Verstärkungspunk erhalten. Gain gain.
Die Verhinderung der Bildung von feinen Rissen um die im Glaskörper zu verändernde Stelle (Reflektor) wird erreicht indem von unterschiedlichen Lasern, aus unterschiedlichen Richtungen eine  The prevention of the formation of fine cracks around the body to be changed in the glass body (reflector) is achieved by a different laser from different directions
Vorerwärmung dieses Areals in einem wohl definierten Temperaturbereich, durchgeführt wird. Preheating this area in a well-defined temperature range, is performed.
Durch diese Vorbereitung wird die im Glaskörper existierende Zug- und Rissspannung abgebaut und bei dem finalen Beschuss durch den Laser, zur Erzeugung des gewünschten Reflektors, wird dieses vorbereitete Areal nur in der Formgebung und Lage beeinflusst (neue Oberfläche im Glaskörper) aber es entstehen keine zusätzlichen ikrorisse. Through this preparation, the tensile stress and cracking stress existing in the vitreous body is reduced and during the final bombardment by the laser to produce the desired reflector, this prepared area is only influenced in its shape and position (new surface in the vitreous body) but no additional energy is generated ikrorisse.
Diese Veränderung schafft die Möglichkeit an der neu geschaffenen Oberfläche eine Totalreflektion zu ermöglichen und den Lichtstrahl in eine zuvor berechnete und gewünschte Richtung zu bringen.  This change makes it possible to allow total reflection on the newly created surface and to bring the light beam in a previously calculated and desired direction.
In der Folge können dann von weiteren, bereits durch das Lasersystem eingebrachte Reflektoren, die weiteren, einfallenden Lichtstrahlen (wie bereits erwähnt) in eine gemeinsame Richtung gebracht werden. Dadurch wird zielgerichtet eine berechnete Verstärkung des Lichtstrahls erfolgen und der gebündelte Lichtstrahl kann zu einem vordefinierten, vorberechneten Austrittspunkt geführt werden. Die Verformung im Glaskörper zur Erzeugung der Reflektoren ist nicht ohne Hilfsmittel (Mikroskope) wahrnehmbar da die, wie bei der Glasinnengravur, vorliegenden Risse nicht mehr vorkommen und damit nicht den Punkt durch die Laserverformung, durch das bloße Auge sichtbar machen und auch keine zusätzliche Instabilität des Glaskörpers hervorrufen. As a result, the further, incident light beams (as already mentioned) can then be brought into a common direction by further reflectors already introduced by the laser system become. As a result, a calculated amplification of the light beam is purposefully carried out, and the bundled light beam can be guided to a predefined, precalculated exit point. The deformation in the glass body to produce the reflectors is not perceptible without aids (microscopes) because, as in the glass engraving, existing cracks no longer occur and thus do not make the point by the laser deformation, visible to the naked eye and no additional instability of the Cause vitreous body.
Die Relativbewegung des Glaskörpers zum Fokus des Laserstrahls, kann jede Position im Glaskörper erreichen und somit auch eine gewollte und Berechnete Struktur der Reflektoren erreichen.  The relative movement of the glass body to the focus of the laser beam can reach any position in the glass body and thus also achieve a desired and calculated structure of the reflectors.
Den in den Patentansprüchen angegebenen Erfindungen liegt das Problem zugrunde, verschiedenartige, in Form und Lage, erzeugte Volumenelemente, im Inneren von Glaskörpern auf möglichst einfache Weise in wirtschaftlich vertretbaren Zeiten zu erzeugen, ohne die mechanischen Eigenschaften des Glaskörpers, zu beeinträchtigen. The inventions stated in the claims is based on the problem of producing various volume elements produced in the form and position in the interior of glass bodies in the simplest possible manner in economically justifiable times, without adversely affecting the mechanical properties of the glass body.
Eine Anwendung kann diese Neuerung in allen optischen Zweigen der Glasindustrie, wie auch der Flachglasherstellung und der Solarzellenproduktion für Photovoltaikanlagen, finden. Auch im Fensterbau würde sich damit eine Möglichkeit der Solarenergiegewinnung eröffnen. One application can find this innovation in all optical branches of the glass industry, as well as in the production of flat glass and solar cell production for photovoltaic systems. Even in window construction would thus open up a possibility of solar energy production.
