Due to its high thermal conductivity and stability, chemical inertness and high critical electrical field compared to other semi-conductor materials, SiC is ideal for applications in harsh environment.
However, SiC is also more and more studied today for its applications in optoelectronics and nanophotonics, becoming a strong competitor to conventional wavelength-conversion materials, such as phosphor/gallium nitride (GaN), for the fabrication of white light emitting sources (LED) [2].

Under the situation of meeting the process and assembly requirements, original design structure is changed, and optimized target is achieved by using lightweight materials to conduct comparison and replacement.
Adopted the space bar structure in original subframe to the new one, it is easy to design and manufacture; but taking the layout location of materials into account, bar section coefficients in feature location are designed to the maximum.
Before subframe lightweight material structure optimization, the initial set of five parts is finished in material parameters, frame constraints, optimization goals, optimization constraints and optimization parameters.
The frame can be optimized just by the use of raw materials for nearly 20% weight loss.

Polycrystalline silicon thin film solar cell what let the polycrystalline silicon thin film grown on low-cost substrate materials uses relatively thin crystalline silicon layer as the activation layer of itself.
As with other solar cell, the working principle of polycrystalline silicon thin film solar cells is the photovoltaic effect of sunlight with semiconductor materials.
The ends of two different material conductors connected to the loop in this technique.
Figure 1 is thermocouple experimental schematic diagram, the heavy line A and thin line B are different materials of conductor, and the conductor of A and B is called the thermocouple.
I believe in the future of materials science development in the future, thermoelectric generation and solar photovoltaic power generation technology can obtain higher power generation efficiency at low cost, and the device will have a brighter future.

Compared with bulk materials, nanoscaled materials have many unique properties, such as small size effect, surface and boundary effect, quantum size effect and so on.
The nanoparticles appear to be the absorbing material for shorter wavelengths (up to approximately 1370nm).
