Substituted thiophene sensitized, nanocrystalline TiO2-based quasi solid-state solar cells were fabricated by using either poly (3-thiophene acetic acid) (P3TAA) or a copolymer with poly (3-thiophene acetic acid)-poly (hexyl thiophene) (P3TAA-PHT) polymers and copper iodide (CuI) as a hole conducting material together with an ionic liquid 1-ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) amide and lithium bis (trifluoromethanesulfone) imide as additives for charge transport promotion. Dramatic enhancements in the cell performances were observed with the additives in CuI. While the cell sensitized with P3TAA generated a short-circuit photocurrent of ~1.45 mA•cm-2, an open-circuit photovoltage of ~345 mV with a total power conversion efficiency of ~0.3% under simulated full sunlight of 100 mW•cm-2 (air mass: 1.5), the cell sensitized with copolymer P3TAA-PHT delivered ~0.25% efficiency under the same conditions with ~1.23 mA•cm-2 as photocurrent and ~371 mV as photovoltage.

复合脱氧后钢液的最终氧含量优于单独脱氧的效果,同时复合脱氧可产生低熔点、易聚合长大的复合夹杂物,实现最佳的脱氧效果。用热力学方法计算了铝-硅-锰复合脱氧的效果,结果表明,在不同硅锰比下,复合脱氧均比单独用铝脱氧的最终氧含量要低;根据脱氧产物为锰铝榴石的原则得出了合金脱氧剂的组成成分。热态试验验证了理论计算结果。
