技術摘要:
本發明係提供一種光電裝置,係包括具有迎光面與背光面之光電半導體薄片,以及具有膠介質及光電轉換粒子之光電轉換件,其中該光電轉換件係設於該光電半導體薄片之迎光面外側,用以吸收及轉換太陽光之波長以提高光電半導體薄片之光電轉換效能。本發明之光電轉換件可針對原本光電半導體薄片所無法吸收的波段作吸收後,再將吸收的能量以該光電半導體薄片所能夠吸收的頻帶放射出來。因此,本發明之光電裝置可達成降低光源吸收干擾及增加入射量,有效減少入射光源能量的浪費及增加光電轉換的效能,因此可應用於簡化太陽能電池製程步驟及降低成本之優點。

The present invention provides a photoelectric device, including a photoelectric semiconductor thin film having a light facing surface and a back light surface; and a photoelectric converter having a medium and photoelectric converting particles mounted on the medium, wherein the photoelectric converter is disposed at an outer side of the light facing surface of the photoelectric semiconductor film for absorbing and converting solar energy so as to enhance photoelectric conversion efficacy. The photoelectric converter absorbs the wavelength that the photoelectric semiconductor thin film cannot absorb, and emits the frequency band that the photoelectric semiconductor thin film can absorb. Thus, the photoelectric device of the present invention decreases the interference of light absorption, increases the light emission, eliminates the wastes of incident light, and increases the photoelectric conversion efficacy. Hence, the fabrication method of the solar cell is simplified, and the cost is decreased in the present invention.
