この発明は太陽電池付き表示素子に関するもの

色に近い色がそのまま見えるので外装品としては
好ましいものではなかつた。 Traditionally, solar cell-equipped electrical equipment uses monocrystalline silicon or amorphous silicon as solar cells and has been incorporated into watches, calculators, radios, etc., but solar cells have a color that is almost black. Since it could be seen as is, it was not desirable as an exterior product.

ことによりこうした従来技術における欠点を解決

コンなどの太陽電池４の発電に寄与する。 In the embodiment shown in FIG. 1, a transmissive display element 1 is arranged over the entire surface. Since the transmissive display element 1 only needs to be able to control the light transmitting state and the light blocking state, a twisted nematic mode liquid crystal display element, a guest-host mode liquid crystal display element, a transmissive electrochromic display element, etc. can be used.
A light diffusing and transmitting layer 2 is provided behind the transmissive display element 1 . The light diffusing and transmitting layer 2 may be made of, for example, a blasted polyester film, or a matte clear lacquer may be applied to the cold mirror 3, which will be described later. The light diffusing and transmitting layer 2 is not necessarily provided behind the transmissive display element 1, but may be provided in front thereof. A cold mirror 3 is provided behind the light diffusing and transmitting layer 2. The cold mirror 3 reflects most of the light in the visible range and transmits infrared light, and its characteristics are shown by dotted lines in FIG. A solar cell 4 is arranged further behind the cold mirror 3. The relative output of amorphous silicon used in solar cells and single crystal silicon is as shown by the solid line in FIG. 2. When compared with the transmittance curve of the cold mirror 3 described above, it can be seen that the power generation contribution rate is higher when single crystal silicon is used. Note that the number of solar cells 4 is not necessarily one, but several solar cells are often connected and used. In part A where the transmissive display element 1 is in the transmissive mode, the incident light 5 passes through the display element and the light diffusing and transmitting layer 2, and the visible light reflected by the cold mirror 3 is diffused by the light diffusing and transmitting layer and comes out, so it is bright. I can see white. On the other hand, in the portion B where the transmissive display element 1 is in the light blocking mode, the incident light is blocked here and appears dark and black. In the end, it is possible to display black on a white background or white on a black background. Note that when a plurality of solar cells 4 are used in series, even if there is a slight gap between them, the back side cannot be seen because the cold mirror 3 reflects most of the visible light. Note that the infrared light transmitted through the cold mirror 3 contributes to power generation by the solar cell 4 made of single crystal silicon or the like.
