Polymer solar cells (PSCs) based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) are fabricated by using 1,8-diiodooctane (DIO) as a solvent additive to control the dop...Polymer solar cells (PSCs) based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) are fabricated by using 1,8-diiodooctane (DIO) as a solvent additive to control the doping density of the PSCs. It is shown that the processing of DIO does not change the doping density of the P3HT phase, while it causes a dramatic reduction of the doping density of the PCBM phase, which decreases the doping density of the whole blend layer from 3.7 × 10^16 cm-3 to 1.2 ×10^16 cm-3. The reduction of the doping density in the PCBM phase originates from the increasing crystallinity of PCBM with DIO addition, and it leads to a decreasing doping density in the blend film and improves the short circuit current of the PSCs.展开更多

Self-transcendence can be reached through self-discipline that is founded upon the fundamental change and potential for existential practice. The mind and the body do not comprise a binary relationship but instead maintain an intimate relationship bound by the medium of organic energy of breathing, breath, and pr^0a. Of these medium that form the relationship, the pr^-0a has a natural healing tendency, which has been well documented within classics such as Upani.sads and Bhagavad G^ta. Classic yoga explains that pr^0a imbues within it a vivacious passion and energy that will connect the human body with the human mind. Thus, the pr^0a functions as bio-energy. From ancient Indian philosophy to Buddhism, yoga therapy actively utilizes practice as a main element. In particular, the Patafijali yoga's methodology details the organic correlation within its eight limbs (支) yoga practices. The prana is breath. This is the only sense in which Patafijali has used this word. Breath is called prana because it moves on continuously throughout the body and reaches the basic circle of the individual self. It pervades mouth, nostrils, heart, navel region and toes. As a result, it is a healing method that achieves far more than the scientific healing methods common in society.展开更多
