U.S. and Indian scientists found in organic photovoltaic materials (organic photovoltaics, OPV) coated with a polymer containing boron nitride nanotubes (Boron-nitride), can significantly increase the life cycle of the solar modules.University of, (Wake Forest University) and the Indian Institute of Technology (Indian Institute of Technology) researchers found that at concentrations of 1.5% nanotubes, will be able to maintain a high degree of transparency in the visible range, enhance heat protection. 

    Polymer solar cell to compare the efficiency of the silicon solar regulator, but have the diversity, and can be applied on a flexible substrate, and therefore still optimistic solar energy intake. However, OPV because of oxidation, exposure to moisture or photochemical reactions and shorten the working life, cause the component to drop (degradation). The David Carroll University noted that the UV light may affect the performance of the polymer component, but if the scattering or absorption to reduce the influence of UV light, the component life can be extended. 

    Boron nitride material for ultraviolet a good scattering effects, while the high aspect ratio nano-tube structure can provide a greater amplitude of oscillation, showing a better behavior of the antenna, therefore compared to the average boron nitride thin film nanotube structure can be a more effective absorption of UV light. In order to produce the boron nitride nanotubes, the team will be equipped with boron, iron oxide, and magnesium oxide, quartz crucible placed in a horizontal alumina tube growth in the environment of 1200 ° C ammonia for 30 minutes, after natural cooling The resultant powder, and then concentrated nitric acid to remove the catalyst particles to leave a multi-wall boron nitride nanotubes. 

    Researchers to packaged food sialon (Saran) as a polymer matrix, this material is good denial of oxygen and moisture better transparency in the visible band, and has good mechanical and thermal stability. In order to assess the degree of protection of the components, the team measured the spectrum of the coated and uncoated composite thin film organic electronic materials P3HT and found that the latter is exposed to the atmosphere for 24 hours on a downgrade signs. And the former joined the nano-materials, but still 93% transmittance in the visible range, far exceeding the 90% of the minimum standards for solar modules.

    In addition, this team has to do in this material 50 to 850 ° C between the assessment of the thermal stability, and found significantly better than the undoped material mixed with 1.5% concentration of boron nitride material on the thermal stability. See Nanotechnology recent. 
  
  Johnson PV buy solar panels power plant using amorphous silicon thin film battery has a significant low-light effect, amorphous silicon cells can still generate electricity in the morning and evening, rain and fog and other low-light conditions than crystalline silicon cells, in the same lighting conditions, the amorphous silicon thin film battery years power generation increased by 12-15%. Attenuation Johnson amorphous silicon photovoltaic power plants using battery power in a high temperature environment, crystalline silicon solar cells in the temperature exceeds 25 degrees when the camera when the photoelectric conversion rate of the formation of the rapid decay curve, while the amorphous silicon small changes, this feature enables the non- crystalline silicon thin-film battery is more suitable for high temperature, high desert regions of use and construction of photovoltaic power plants. 

    Johnson photoelectric production of amorphous silicon thin film batteries and the construction of photovoltaic power projects the maximum characteristics and advantages of solar cell products prices decline, the cost of power generation for about 40% of the crystalline silicon cost of power generation, photovoltaic power generation in the central and western China remote areas, especially the shortage of film popularized in applications possible.
