在理论研究的基础上，提出了一种新的染料敏化纳米晶光电电池结构，该结构可以使用更薄的染料敏化膜有效地吸收入射太阳能。该电池通过底部分散的TiO2颗粒的多次散射和表面插入的TiO2薄膜与玻璃衬底之间的全反射，有效地限制了入射光在较薄的染料敏化薄膜中的入射光。在最优散射条件下，当后向散射角等于表面的临界反射角时，后向散射强度最大。光约束对长波长光也有效。(C) 1997爱思唯尔科学有限公司
A new structure of dye-sensitized nanocrystalline photoelectrochemical cell, which permits effective absorption of incident solar energy using thinner dye sensitized film, is proposed based on theoretical examination. The cell effectively confines incident light in the thinner dye-sensitized film by multiple scattering from dispersed TiO2 particles at the bottom and total reflection between the inserted TiO2 film and the glass substrate at surface. Under optimal scattering conditions, the backscattered intensity is maximized when the backscattering angle is equal to the critical angle of reflection at the surface. The optical confinement is also effective for long wavelength light. (C) 1997 Elsevier Science B.V.
