硒蒸气硒化法制备CIGS薄膜的影响因子(I)氩气流量对CIGS薄膜结构和形貌的影响 总被引:1,自引:0,他引:1
采用中频交流磁控溅射方法,在Mo层上沉积了CuInGa(CIG)预制膜。以Ar为载气,采用固态硒化法制备获得了cu(In1-xGax)Se2(CIGS)吸收层薄膜,考察了Ar流量对CIGS薄膜结构和形貌的影响。采用SEM和EDS观察和分析了薄膜的表面形貌和成份,采用XRD表征了薄膜的组织结构。结果表明,在不同血流量下制备的CIGS薄膜均具有单一的黄铜矿相结构,薄膜具有(112)面的择优取向。随着Ar流量的增大,CIGS薄膜晶粒直径增大。当舡流量为0.20m^3/h时,薄膜的孔隙最少。当Ar流量达到0.40m^3/h时,薄膜晶粒出现明显的柱状生长。当心流量为0.10、0.20和0.30m^3/h时,所制得的CIGS薄膜的Cu、In、Ga原子含量比,处于弱P型的理想范围。 相似文献

CdTe thin film solar cells: device and technology issues 总被引:1,自引:0,他引:1

Polycrystalline thin film CdTe continues to be a leading material for the development of cost effective and reliable photovoltaics. Thin film CdTe solar cells and modules are typically heterojunctions with CdS being the n-type partner, or window layer. The preferred configuration for CdTe solar cells is the superstrate structure. The cadmium chloride heat treatment, the back contact formation process, and the utilization of resistive, buffer layers in tandem with a thin cadmium sulfide window layer, are important areas of research in thin film CdTe solar cells. This paper reviews work on CdTe thin film solar cells sponsored by the National Renewable Energy Laboratory. Results for a vapor chloride heat treatment with high throughput characteristics, a dry back contact process, and a comparative study of resistive buffer layers and their effect on the performance of CdTe solar cells are presented. 相似文献

Recent advances in solar cell device technologies are surveyed, and a new trend underlying is predicted by a term “technological evolution from the bulk crystalline age to the multilayered thin film age”. In the paper, firstly, recent progress of thin film fabrication technologies for active materials of photovoltaic device are reviewed, and their significancies such as wide area, low temperature growth etc., are pointed out from currently developed live technologies. Secondly, some R & D efforts to develop the next generation type solar cells utilized by full use of multi-layers thin film growth technology are introduced together with some newly developed integrated process technology for the thin film solar cells. Then, some topics in the high cost performance multi-layers thin film solar cells are also introduced. In the final part of this paper, the current state of the art in the field of thin film solar cells and their industrialization are overviewed and the market expansion toward the 21st century is forecast, and discussed. 相似文献

We have developed an optical analysis method to design the structure of multi-layer thin film solar cells. The optimised thickness of the individual layers in any single as well as tandem type thin film a-Si:H solar cells ban be obtained. By minimising the reflectance using an optimal anti-reflection coating layer and selecting a suitable rear contact material, a significant increase in the photon collection efficiency at long wavelength can be achieved. The effect of the variation in the thickness of different layers on the performance characteristics of a cell is discussed. The calculated results and analyses show that the present theoretical approach can be used directly to design any thin film solar cell with an optimised structure for a desired high conversion efficiency. 相似文献

High efficient large area thin film polycrystalline Si solar cell based on a silicon on insulator (SOI) structure prepared by zone-melting recrystallization (ZMR) is reported. Fabrication process of the via-hole etching for the separation of thin films (VEST) is newly developed. It is found that phosphorus treatment and back surface field (BSF) are quite effective for the VEST structure and the ZMR thin film polycrystalline silicon. The conversion efficiency as high as 16.0% for a practical size (10 cm×10 cm) is achieved. This is the highest for large area thin film polycrystalline Si solar cells ever reported. 相似文献
