The characteristics of pentacene/perylene derivatives based organic solar cells are investigated in this thesis Donor and acceptor layers are pentacene and N N'-dioctyl-3 4 9 10-perylenetetracarboxylic diimide (PTCDI-2~13C) respectively Twelve organic solar cells with pentacene/PTCDI-2~13C heterojunctions were fabricated to study the influence of various alkylic perylene derivatives on the power conversion efficiency Under the sunlight simulator with AM1 5G filter and 100 mW/cm2 the solar cell of pentacene/PTCDI-7C heterojunction with cathode of Ag/Al bilayer has the best performance among the devices with pentacene/PTCDI-2~13C heterojunctions In PL spectrum analyses the pentacene/PTCDI-7C film had lower recombination rate than the other pentacene/PTCDI-2~13C films; therefore more excitons could reach the P/N junction and enhance short-circuit current Furthermore the PTCDI-7C film grown on the surface of penatcene was more matched than other PTCDI films analyzed by the PL peak shifts of 10 nm and 45 nm thick PTCDI-2~13C and images of atomic force microscope More lattice match between the films of pentacene and PTCDI resulted in fewer defects in P/N junction and more carries can reach electrodes Accordingly the power conversion efficiency approach 2% was obtained from the solar cell with the active layer of pentacene/PTCDI-7C

本研究探讨以五环素/骈苯衍生物异质接面太阳能电池之特性，利用pentacene作为电子施体有机材料，PTCDI -2C~13C作为电子受体有机材料，制作出异质接面为pentacene/ PTCDI-2C ~13C等12种有机太阳能电池，比较不同碳数的骈苯衍生物对於有机太阳能电池之光电转换效率之影响。在AM1 5G、100 mW/cm2的模拟太阳光下，以pentacene/PTCDI-7C异质接面太阳能电池具有短路电流9 882 mA/cm2、开路电压0 376 V、填充因数0 523及光电转换效率达1 945%，皆比其他pentacene/PTCDI-2C ~13C异质接面太阳能电池来的大。由薄膜分析可知PTCDI-7C在这12种太阳能电池中具有较低的电子电洞复合发光效率，可以让较多激子到达异质接面进行电荷分离，减少电子电洞对复合发光的机率；此外，由光激发萤光光谱之峰值位移配合原子力显微镜表面结构图，可以得知当PTCDI-7C成长在pentacene上时会顺著pentacene的结构成长薄膜，故较无缺陷产生在P/N接面处；而在其他结构下则无此现象产生，致使在pentacene/PTCDI-7C薄膜中的载子有较大的机会可以移动至电极，使光电流提高，进而使光电转换效率提高。

But with the arrival of the countdown, the screen appeared a beautiful image of Lijiang, followed by a variety of ethnic minorities out of Monty, the full platform of the station, which is only found in the plane looked yellow background, it is three-dimensional tea Horse Road, every layer of all of a small winding road, a small inconspicuous hole, the actor who inadvertently from a hole in one to emerge from the first stage of a few people, all of a sudden change Into dozens, hundreds, mighty, there are people who, after riding the bypass, coupled with a very beautiful, soft music, is simply too beautiful.

但进入倒计时，屏幕上出现一个美丽的形象，丽江，其次是各种少数民族的蒙蒂，充分平台站，只发现了飞机看着黄色背景，它是三三维茶马古道，每一层的所有小曲折的道路，一个小不显眼的洞，演员谁无意中从一个洞，一个摆脱了第一阶段的几个人，突然转变为几十，几百人，强大的，有人民谁，骑车绕行，加上非常漂亮，轻音乐，太漂亮。

So when I was around 14 and my younger sister wanted to get her ears pierced, I had a moment of stunning clarity, like one of those kung fu slow motions in a Crouching Tiger film, where I realized that drilling a hole in your ear lobe is just…well…odd.

所以当我大约14岁时，我的小妹想要穿耳洞，我有片刻惊人的清醒，就像是在一部"卧虎藏龙"电影中的其中一个功夫慢动作，我意识到在你的耳朵上挖一个洞只是有些。。。是的。。。奇怪的。

From a puckered hole in the corpse's desiccated trunk rose the stump of an arrow, broken off a handsbreadth above the ribs.

尸体的变干的躯体上，肋骨上面，有一个带着折皱的洞，洞里，插着断了的四英寸长的半载箭。

The top of the shapeless bay into which this door shut was masked by a narrow scantling in the centre of which a triangular hole had been sawed, which served both as wicket and air-hole when the door was closed.

在那不成形的门框上端，有一块狭窄的薄木板，板的中间，锯了一个三角洞，那便是在门关了之后的透光洞和通风洞。

He described how he labored with her and convinced her; and how she almost died for joy when she had groped to where she actually saw the blue speck of daylight; how he pushed his way out at the hole and then helped her out; how they sat there and cried for gladness; how some men came along in a skiff and Tom hailed them and told them their situation and their famished condition; how the men didn't believe the wild tale at first,"because," said they,"you are five miles down the river below the valley the cave is in"-then took them aboard, rowed to a house, gave them supper, made them rest till two or three hours after dark and then brought them home.

她知道她活不长了，也愿意死去。他描述了他费尽口舌去说服她，等她摸索到能看见蓝色天光的地方，她简直高兴死了；他是怎样挤到洞外，然后帮忙把她也拉出了洞，他俩怎样坐在那儿，高兴得大喊大叫；然后有几个人是如何乘小艇经过，汤姆招呼他们，并讲明自己的处境：已经断炊。那几个人起先如何不相信这荒唐的事，因为他们讲&你们呆的山洞在河下游五英里处&——然后把他俩弄上小艇，划到一座房子处，让他俩吃了晚饭，天黑后休息了两三个小时，才把他们带回家。

Hence, the Tungs should be out and living in this world like regular persons do.

战：我此刻终於明白，除非这世上处处是水月洞天，否则不可能有一个遗世独立的净土存在，一群封闭在绝世的人，只会成为世间私心和邪恶的目标，所以童氏一族应该出来，在红尘中像普通人一样生活，带著心中的水月洞天，建出新的家园

Visiting or living in China every year over the past three decades, I have had the personal opportunity to witness dramatic transformations. When I first went to China in 1979, vestiges of the Cultural Revolution were still evident: revolutionary slogans painted on walls and pockmarks on university buildings from bullets and howitzer shells shot by dueling Red Guards.

在过去的30年中，我每年到中国访问或居住，有机会目睹了中国戏剧性的改革。1979年我第一次到中国时，文化大革命的残余仍然明显：很多墙上涂着革命口号，大学的建筑物上布满了弹洞，这些弹洞是红卫兵武斗时发射炮弹和子弹所遗留下来的。
