Solar cells are the mainstream of renewable energy, since solar energy is abundant and accessible to most places on Earth. However, it has drawbacks, such as low energy conversion commonly less than 20 %, the power supply is intermittent and not stable. In industry, the energy conversion efficiency versus cost is the first priority to promote. Thus, implementing low cost but effective technique is attractive to industry. Based on geometric and wave optics, two simple-integrated and scalable techniques to improve the energy conversion of solar cells are developed. The first method is to make a v-groove structure on the encapsulant, …

Electrospinning is a versatile and inexpensive method to fabricate micron-sized polymer fibers, and it has been employed in this work to develop highly anisotropic fibrous composites. Previous work has detailed the properties of using electrospinning to fabricate fibrous anisotropic composites that was achieved by embedding stiff fibers in an elastomeric matrix. The goal of this work is to achieve anisotropic composites through creating a layering of rigid and elastic fibers in a laminate structure using primarily electrospinning in the fabrication. The composite produced has a unique deformation pattern when strained perpendicularly. The rigid fibers experienced no entanglement with each other …
