1. Effects of thermal-annealing and processing-additive treatment in organic solar cells　(OSCs): Effects of thermal-annealing and processing-additive treatment on crystallization-induced phase separation and photovoltaic performance in bulk heterojunction (BHJ) OSCs utilizing non-peripherally substituted octapentyl tetrabenzotriazaporphyrin (C5TBTAPH2) mixed in 1-(3-methoxycarbonyl)propyl-1-phenyl-(6,6)C71 (PCBM) were reported. By using either thermal-annealing or processing-additive treatment, the C5TBTAPH2-crystallite sizes in the BHJ films were enlarged and the power conversion efficiencies (PCEs) were increased due to improvement of the crystallization-induced phase separation. However, the optimum PCE of the processing-additive treated devices was higher than those PCE of devices treated by thermal annealing. These results were discussed by taking the thermal properties and molecular aggregation of PCBM into consideration.2. All-solution processalbe tandem cell using mesogenic phthalocyanine: The photovoltaic performance of BHJ OSCs using C6TBTAPH2 limits due to the weak absorption at around 500 nm. I have fabricated the tandem solar cell with all-solution processed multilayer structure utilizing a conventional structure composed of C6TBTAPH2 and poly(3-hexylthiophene) (P3HT). The P3HT single cell give a maximum the external quantum efficiency at 500 nm, and the C6TBTAPH2 single cell has two predominant peaks at 720 and 350 nm. The tandem solar cells with stacking of the two composite thin films cover the all visible spectral range and the PCE of 3.2% was achieved.

1.有机太阳能电池(OSCs)中热退火和工艺添加剂处理的影响：报道了非外周取代的八碳戊基四苯并三氮杂卟啉(C5TBTAPH2)与1-(3-甲氧基甲酰基)丙基-1-苯基-(6，6)C71(PCBM)混合的体相异质结(BHJ)电池中热退火和工艺添加剂处理对晶化诱导相分离和光伏性能的影响。通过热退火或工艺添加处理，BHJ薄膜中的C5TBTAPH2微晶尺寸增大，晶化诱导相分离改善，功率转换效率(PCE)提高。然而，加工添加剂处理的器件的最佳PCE高于热处理的器件的PCE。结合PCBM的热学性质和分子聚集性对这些结果进行了讨论。全溶液工艺采用介晶酞菁的串联电池：由于在500 nm附近的弱吸收，使用C6TBTAPH2的BHJ OSCs的光伏性能受到限制。利用C6TBTAPH2和聚(3-己基噻吩基)(P3HT)组成的传统结构，制备了全溶液处理多层结构的串联太阳电池。P3HT单电池在500 nm处有最大的外量子效率，而C6TBTAPH2单电池在720和350 nm处有两个优势峰。两种复合薄膜堆叠而成的串联太阳电池覆盖了全可见光谱范围，获得了3.2%的光电转换效率。
