    • A thin film photovoltaic module has transparent electrodes on front and back surfaces of a semiconductive layer. In one embodiment, both transparent electrodes pass light to the semiconductive layer for photovoltaic purposes. In another embodiment, the back electrode passes light which enters through the front electrode and is not absorbed by the semiconductive layer, so that the module is selectively transparent to the unabsorbed light. The spectral makeup of the transmitted light is controlled by controlling the optical characteristics of the layers of the module. The index of refraction of the back electrode is a primary source of transmission control, along with the refractive index of the front electrode and the thickness of the semiconductive layer itself. Light transmitted by the module can be used for nonphotovoltaic purposes, such as illuminating the interior of a vehicle or dwelling, or may be directed back into the semiconductive layer by a reflective surface behind the back electrode.
    • 薄膜光伏模块在半导体层的前表面和后表面上具有透明电极。 在一个实施例中,两个透明电极将光传递到用于光伏目的的半导体层。 在另一个实施例中,背电极通过进入前电极的光并且不被半导体层吸收,使得该模块对未吸收的光选择性地透明。 通过控制模块的层的光学特性来控制透射光的光谱组成。 背面电极的折射率是传输控制的主要来源,以及前电极的折射率和半导体层本身的厚度。 由模块传输的光可以用于非光伏目的,例如照亮车辆的内部或住宅,或者可以通过后电极后面的反射表面引导回到半导体层。

    • A solar powered light adapted to be mounted under the eaves of a building, a wall or the like for use in security applications. In a preferred embodiment of the present invention, the solar powered light comprises an adjustable configuration having a lamp with an infrared detector or sensor rotatably mounted thereto and a photovoltaic or solar cell array rotatably disposed at a remote end of an extension arm movably attached to the lamp. Such a flexible arrangement allows the photovoltaic array to be positioned to receive direct sunlight. The sensor activates the solar powered light upon sensing infrared to illuminate the surrounding areas when a presence is sensed and turn it off when a presence is no longer sensed. In accordance with a second embodiment, the solar powered light does not include an infrared detector and provides continuous illumination for a given period of time. In accordance with a third embodiment, the solar powered light does not include an infrared detector, but includes a battery having a higher capacity configured to provide illumination for extended periods of time. In accordance with a fourth embodiment, the solar powered light is configured to be used directly with a user's battery. The solar powered light utilizes a compact fluorescent bulb and circuitry for providing longer lamp life, instantaneous illumination and eliminating flickering during start up.
