大面积染料敏化的光电化学太阳能电池是用高导电性和光学透明的玻璃制成的，玻璃由内层氧化铟锡和外层氟掺杂氧化锡组成。本文描述了一种沉积TiO2纳米晶膜的方法，该膜由大小中值粒子（分别为30 nm和5 nm）组成，可促进孔隙率和光散射。将微量的氧化镁掺入TiO2中可以提高细胞的效率。研究发现，面积为21 cm2的电池（AM 1.5, 1000 W m−2模拟阳光）的能量转换效率为7.2%，而不含氧化镁的电池的能量转换效率为5.6%。讨论了氧化镁提高电池性能的机理。版权所有©2006约翰威利父子有限公司
Dye‐sensitized photoelectrochemical solar cells of large area are fabricated using highly conducting and optically transparent glass consisting of an inner layer of indium‐tin oxide and an outer layer of fluorine doped tin oxide. A method is described for the deposition of nanocrystalline films of TiO2 consisting of large and small median size particles (30 and 5 nm, respectively) which promote porosity and light scattering. Incorporation of trace quantities of magnesium oxide into TiO2 increased the efficiency of the cells. The energy conversion efficiency of a cell (AM 1·5, 1000 W m−2 simulated sunlight) of area 21 cm2 was found to be 7·2% compared to 5·6% in the absence of magnesium oxide. The mechanisms by which the magnesium oxide improves the cell performance are discussed. Copyright © 2006 John Wiley & Sons, Ltd.
