In the present invention a new solar photovoltaic module is proposed comprising: a silicon based photovoltaic element; an intermediate layer deposited on said photovoltaic element to the incident light side; an interference filter deposited on the incident light side of said intermediate layer; a front element disposed on the incident light side of said interference filter. Said intermediate layer has a transparency of at least 90% for infrared light between 780nm and 1200nm and said interference filter is corrugated and composed of a multilayer comprising a plurality of dielectric layers designed to transmit at least 75% of the total incident solar infrared light between 780nm and 1200nm, and to reflect and diffuse incident visible solar light such that the perceived color of said reflected and diffused visible light by any observer positioned anywhere to the incident light side of said solar photovoltaic module and looking towards the front element of said solar photovoltaic module is defined by a Y10 tristimulus value not lower than 50 defined by an x value of 0.20 to 0.45 and a y value of 0.20 to 0.45 in a chromaticity diagram of a CIE 1964 Yxy color system using a white light source measured with a D65 light source with a 10-degree angular field.

4. WOWO/2014/169922 - SOLAR AIR COLLECTOR23.10.2014
H01L 31/052
PCT/DK2014/050100UDLEJER HANS JØRGEN CHRISTENSENCHRISTENSEN, Hans Jørgen
The present invention relates to a solar air collector (1) with an opening in the rear side (3) where a solar cell (2) can be fitted and maintained in such a way that it can receive sunlight (7) via the transparent cover (6) of the solar air collector. The solar cell (8) can now dissipate waste heat to the rear in such a way that it is not overheated by a fan stop. When the solar air collector (9) is mounted with a little distance on a wall (18) most of the dissipated heat from the solar cell to the air on the rear side will be sucked into the solar collector and hereby not loss energy. A solar cell can now be replaced without intervention into the solar collector. It is possible to mount side plates (10) on the solar collector (9) due to the improved cooling of the solar cell which will protect against direct wind chill of the rear side of the solar collector and will also preheat the intake air (11) before it enters the solar collector by rays of sunlight (7) hitting the side plate (10). The side plates may be used when mounted on a wall (18). It is possible to mount a protective plate (14) preferably made in metal over the solar cell (15) for protection of the solar cell against driving rain, wind chill, mechanical impact from snow or knocks. The plate is provided with black felt (23) on the underside in order to better receive the radiated heat from solar cell (2) when this is heated by the sun. The large surface of the felt can hereafter more efficiently dissipate the heat to the self-circulating air which enters at (20) and leaves at (21) when the solar collector is not forced ventilated or leaves at (22) when the fan pulls the air in at (13). Here the air heated by the waste heat of the solar cell will be pulled into the solar collector.
