Description
本發明是有關於一種薄膜太陽能電池光柵,特別是有關於一種使用雷射光產生固定光柵圖樣的薄膜太陽能電池光柵,相對於運動方向垂直於光柵且速度值大於固定值的物體,使用者可透過該薄膜太陽能電池光柵觀看該移動之物體。 The present invention relates to a thin film solar cell grating, and more particularly to a thin film solar cell grating using a laser beam to generate a fixed grating pattern, which is transparent to an object whose direction of motion is perpendicular to the grating and whose velocity value is greater than a fixed value.

目前,國際能源價格逐漸高漲,各國均致力於太陽能電池的研究及應用,以獲得便宜且無環境汙染之能源。薄膜太陽能電池可以使用各種價格低廉的玻璃、塑膠、陶瓷及石墨等不同材料做為基礎來製造,形成的可產生電壓的薄膜厚度僅需幾毫米。因此相較於矽晶圓太陽能電池,在相同的受光面積下薄膜太陽能電池可以節省大量原料的用量,且具有優良的能量轉換效率,薄膜太陽能電池除了平面之外,也因為具有可撓性,可以製作成非平面結構,可與建築物結合或是變成建築物的一部。 At present, international energy prices are gradually rising, and all countries are committed to the research and application of solar cells to obtain cheap and environmentally friendly energy. Thin-film solar cells can be fabricated using a variety of inexpensive materials such as glass, plastic, ceramics, and graphite.

一般來說,人類的眼睛會把看到的影像暫時停留在視網膜上1/24秒。對剛剛消失的影像產生「依然存在」的錯覺。運用此一原理,電影才能捕 捉瞬息萬變的光影,將這些圖像拍攝在膠卷上,再迅速投射到銀幕上,以每秒播放24格影片,讓觀眾的視覺效果,在上一個圖像尚未消失前,立刻銜接下一個圖像,因而產生連續活動的效果,這就是所謂的「視覺暫留」原理。 In general, the human eye will temporarily hold the image seen on the retina for 1/24 of a second. The illusion of "still exists" for the image that just disappeared. Using this principle, the film can catch Capture the ever-changing light and shadow, take these images on the film, and then quickly project them onto the screen to play 24 frames per second, so that the viewer's visual effect will immediately connect the next image before the previous image has disappeared. , thus producing the effect of continuous activity, which is the so-called "visual persistence" principle.
有鑑於該視覺暫留之原理,本發明經雷射切割以形成複數個透明光柵111之薄膜太陽能光柵1裝設於一物件上時,該複數個光柵111係與該物件之運動方向或是欲觀察外在物體之運動方向可呈垂直。而此時若裝有薄膜太陽能電池光柵1之該物件與外在物體或環境之間之相對速度值大於0.5km/hr時,該薄膜太陽能電池光柵1將產生近似透明之效果,讓使用者得以透過該些透明光柵111觀測到外在物體或環境,如第6圖所示。 In view of the principle of the persistence of vision, when the thin film solar grating 1 of the present invention is laser-cut to form a plurality of transparent gratings 111, the plurality of gratings 111 are related to the moving direction of the object. Observe that the direction of motion of the external object can be vertical. At this time, if the relative velocity value between the object containing the thin film solar cell grating 1 and the external object or environment is greater than 0.5 km/hr, the thin film solar cell grating 1 will have an approximately transparent effect, allowing the user to An external object or environment is observed through the transparent gratings 111 as shown in FIG.
綜合上述,本發明之透視動態影像之薄膜太陽能電池光閘,主要係將原本全面積之薄膜太陽能電池模組以雷射光剝除部分面積,形成特定圖樣之透明光閘,再與前後背板及金屬外框組合成為薄膜太陽能電池光閘,當裝設於物件上時,除發電之外,使用者可以透視到位於光閘背面以相對時速大於0.5km/hr且方向垂直於光閘圖樣之物體,如此可以增加薄膜太陽能電池之應用範圍。 In summary, the thin-film solar cell shutter of the dynamic image of the present invention mainly uses a full-area thin film solar cell module to strip a part of the area by laser light to form a transparent shutter of a specific pattern, and then the front and back back sheets and The metal frame is combined into a thin film solar cell shutter. When mounted on the object, in addition to generating electricity, the user can see through the object located on the back of the shutter with a relative speed of more than 0.5km/hr and a direction perpendicular to the shutter pattern. This can increase the range of applications of thin film solar cells.
