太阳能电池是一种大有前途的新型电源．那么,什么是太阳能电池呢？太阳能电池是利用太阳能发电的装置．简单说来,太阳能电池是一个半导体光电二极管,当太阳光照到光电二极管上时,光电二极管就会把太阳的光能变成电能,产生电流．当然,一个光电二极管产生的电能是很小的,但是,许多个电池串联或并联起来就可以成为有比较大的输出功率的太阳能电池方阵了．太阳能电池一般分为单晶硅太阳能电池和其它太阳能电池两大类,而其它太阳能电池又可分为薄膜太阳能电池和非薄膜太阳能电池．单晶硅太阳能电池因其光电转换效率高、制造工艺成熟、可… 相似文献

日本多家企业正在着手批量生产由非晶硅和多晶硅构成的混合型太阳能电池，其光电转换效率可超过10％。
据此间报纸报道，这种混合型太阳能电池的制作方法是，首先在玻璃基板上制作非晶硅，再用硅烷气使之形成非晶硅薄膜，然后在200摄氏度的温度下使它和多晶硅薄膜结合在一起，即可形成双层结构的混合型太阳能电池。其厚度是，非晶硅层0.3微米，多晶硅层1.5微米。由于它能利用太阳光中的包括可见光与红外光波段的所有光波，因此大大提高了光电转换效率。
目前，两家日本公司正在建设生产这类太阳能电池的工厂，为批量生产作准备。 相似文献

The global warming issues were discussed in Part 1 of this series of articles. This part describes the different solar energy technologies that are available for generating electricity to meet our daily power requirement. The article focuses on different kinds of materials that can be used to make the photovoltaic cells. The most common photovoltaic cells are made with monocrystalline or polycrystalline silicon. The next generation photovoltaic cells are thin film based. The high efficiency multijunction and concentrated solar cell technologies are also introduced in this article. The concept of power generation using solar thermal energy is explained. In the Indian scenario, there are about 250–300 sunny days in most parts of the country. A brief summary of the solar sector achievements in the country is given. 相似文献

The dream of generating electricity from sunlight in large scale at low cost may not be that far from reality in this century.
Rapidly emerging solar energy technology using low cost dye sensitized photovoltaic cells on plastics would be a real boost
for the third world countries. Though the conventional silicon solar cells are efficient in converting solar energy into electricity
until now, the non conventional solar cells based on molecular photosensitization by colored materials in wide band gap semiconductors
is a fast growing field of basic scientific and industrial research. Present state-of-the-art cells using molecular dyes shows
energy conversion efficiencies of 10–11%. In this article, we present the concept of dye-sensitized photovoltaic (DSPV) cell
and the progress in current research. The important contributions of molecular dyes that are used as photosensitizers in these
photovoltaic or solar cells are also described. 相似文献

The pressure to reduce solar energy costs encourages efforts to reduce the thickness of silicon wafers. Thus, the cell bowing problem associated with the use of thin wafers has become increasingly important, as it can lead to the cracking of cells and thus to high yield losses. In this paper, a systematic approach for simulating the cell bowing induced by the firing process is presented. This approach consists of three processes: (1) the material properties are determined using a nanoidentation test; (2) the thicknesses of aluminum (Al) paste and silver (Ag) busbars and fingers are measured using scanning electron microscopy; (3) non-linear finite element analysis (FEA) is used for simulating the cell bowing induced by the firing process. As a result, the bowing obtained using FEA simulation agrees better with the experimental data than that using the bowing calculations suggested in literature. In addition, the total in-plane residual stress state in the wafer/cell due to the firing process can be determined using the FEA simulation. A detailed analysis of the firing-induced stress state in single crystalline silicon (sc-Si), cast, and edge-defined film-fed growth (EFG) multi-crystalline silicon wafers of different thicknesses is presented. Based on this analysis, a simple residual stress calculation is developed to estimate the maximum in-plane principal stress in the wafers. It is also proposed that the metallization pattern, Ag busbars and fingers screen printed on the front of a solar cell, can be designed using this approach. A practical case of a 3-busbar Si solar cell is presented. 相似文献

The accelerated life test was carried out to investigate the change of spectral transmittance of di-methyl silicon oil and the effects on the electrical performance of silicon solar cell. The di-methyl silicon oil samples before and after accelerated life test were analyzed by FT-IR, GC-MS and LC-MS. The ring compounds and linear compounds with larger molecular weight were detected. The spectral transmittance of di-methyl silicon oil decreased because the chromophore and auxochrome of the products made a sunlight receive decrease on the surface of the solar cell, and resulted in the reduction of cell performance. According to the decrease of spectral transmittance of di-methyl silicon oil, two recovery methods were proposed. The results showed that extraction was superior to vacuum distillation in recovering the aged di-methyl silicon oil. 相似文献
