At the early development of polymer solar cells, a planar p-n junction structure represented the mainstream in mimicking conventional silicon-based solar cells. However, the obtained devices demonstrated poor photovoltaic performances due to the long distance between the exciton and junction interface and insufficient light absorption due to the thin light absorber. It was not until 1995 that the dilemma was overcome with the discovery of a novel bulk heterojunction in which donor and acceptor form interpenetrated phases. Poly[2-methoxy-5-(2 -ethylhexyloxy)-p-phenylene vinylene] was blended with Ceo or its derivatives to form the bulk heterojunction. A much improved power conversion efficiency of 2.9% was thus achieved under the illumination of 20 mW/cm. (Yu et al., 1995). The emergence of the donor/acceptor bulk-heterojunction structure had boosted the photovoltaic performances of polymer solar cells. Currently, a maximal power conversion efficiency of 10.6% had been reported on the basis of synthesizing appropriate polymer materials and designing a tandem structure (You et al., 2013). The detailed discussions are provided in Chapter 5.

The effect of silicone oil and carboxylated silicone on intraocular lenses was studied with FTIR spectroscopy. It was noticed that washing with n-pentane removed the adhered silicone oils from two types of lenses, while residual oil was detected in other cases [22], The development of sequential interpenetrating polymer network (IPN) based on poly(2-methacryloyloxyethylphosphorylcholine) and silicone was studied with FTIR spectroscopy. It was discovered that IPN possesses reduced protein absorption tendency compared to pristine silicones and can be used as a novel ophthalmic biomaterial [23]. The stimuli responsive ultra-thin diblock copolymer brushes were developed on the surface of silicone rubber and studied with FTIR spectroscopy. The authors studied the thermally-induced evolution mechanism of various interactions using...
