3 SCHOTT photovoltaic modules turn a roof or a façade into a solar power plant. Both technologies are extremely cost efficient because the high performance thin-film elements also perform all of the functions of a modern outer shell. The semi-transparent SCHOTT ASI THRU allows for the passage of light, while SCHOTT ASI OPAK, is the perfect solution for opaque surfaces. 3

4 4 Harness the sun Glass that generates energy SCHOTT s photovoltaic modules are known for their long life expectancy, high performance and low investment costs. Once they have been functionally and aesthetically integrated into the building shell, they deliver decades of consistent performance. High-performance semi-conductors ASI modules are produced using the most successful thin-film technology. Based on amorphous silicon, it not only ensures high energy output even under overcast or partly shaded conditions, it also stands up to the high temperatures common to building-integrated appli cations. Solar modules from SCHOTT are free of toxic additive arsenic and heavy metals such as cadmium or indium; their uniform surface lends them an impressive appearance. A variety of options The semi-transparent ASI THRU modules are known for their light intensity, while ASI OPAK, is ideal for opaque, homogeneous surfaces. Both versions are available as laminated safety glass or insulating glass elements. This opens up a number of design options with all the structural-physical advantages of conventional glass façades. ASI glass modules not only supply energy, they also reduce consumption by allowing for a precisely engineered interplay between heat insulation and energy yield, transparency and shade. Low maintenance Excellent insulation The elements can be installed in a variety of different mullion-transom constructions to form wall claddings, canopies, skylights or flat and pitched roofs. The result is a low maintenance building shell that also provides ex cellent solar and thermal insulation. ASI THRU insulating glass elements achieve the same G-values as high quality sun protection systems installed on the outside. At 1.1 W/m²K, their U-value is equal to that of an insulating glass unit with low-e thermal insulation coating.

9 ASI Glass with 2 sub-modules Technical Data Sheet ** Electrical data for steady state under standard test conditions (STC: W / m², AM 1.5, cell temperature: 25 C). The nominal power can be about 18% higher than the specified performance data initially. This performance bonus needs to be taken into consideration when designing a system. All electrical data listed is subject to a production variation of ± 10%. *** The SHGC values listed are approximate values. Temperature coefficient of the cells Nominal power Open-circuit voltage Short-circuit current Tk (Pn) Tk (Uoc) Tk (Isc) 0.20 % / K 0.31 % / K % / K Instructions on designing the system Positive grounding Shading Reverse current System voltage For all modules based on ASI glass technology, care must be taken to ensure that a negative ground is not established. This requirement must be met by using an appropriate system design. The ASI glass technology is highly tolerant of shading. Nevertheless, shades and blinds that cover up an entire cell must be avoided. Shadows that run perpendicular to the cells and thus cover the surface of each cell do not cause any damage to the semiconductor. It is recommended each string is backed up with a fuse. It should be noted that the maximum reverse current must not exceed twice the short-circuit current. The maximum system voltage may not be exceeded at any time. Under normal operating conditions, photovoltaic modules can have higher currents and / or voltages than described under standard test conditions. Product code: ASI THRU 2 L ASI THRU-2-L Appearance of the semiconductor Technology Number of sub-modules Version: L = Laminate / IO = Insulating glass (also as over-head glazing) The semiconductor coating may have slight colour variations both within a sub-module and from sub-module to sub-module. These colour shades are driven by optical interferences within the semiconductor layer and are caused by the production process. This effect does not affect the electrical function or the life of the modules and is a product feature. Glass and laminating film quality Glass Annealed glass: tempered glass according to DIN EN Laminated safety glass: (float glass / PVB film / float glass) according to DIN Laminating film Only PVB (polyvinyl butyral) films with the following mechanical properties are used for all laminated glasses mentioned: Tensile strength > 20 N/mm² Breaking elongation > 250 % The edges of all annealed glasses are chamfered. The edges of the laminated safety glass panes are cut. There may be some small bubbles in the border area or in the visible surface. These are not defects in the elements.
