現在越來越多的企業投入到了“陽光計劃”的隊伍中，積極的開發太陽能，雙登蓄電池污染問題也變得日益凸顯，變得令人觸目精心。
Now more and more enterprises into the "sunshine plan" in the team, the positive development of solar battery, dual pollution problems have become increasingly prominent, has become an eye-catching carefully.

作為市場上最主流的儲能設備，目前還沒有電池產品能夠代替雙登蓄電池。通過檢查與整改，雙登蓄電池產業得到了不斷的升華。與此同時，在使用過程中無排放，無噪音，無能耗的清潔能源太陽能電池，也得到了人們的大力支持。但當今主流卻忽略了太陽能電池光鮮表面背后生產過程中的高污染、高能耗的問題。
As most of the mainstream market storage device, there is no battery products can replace the lead-acid battery. Through inspection and rectification, lead-acid battery industry has been continuously sublimation. At the same time, in the process of using no emissions, no noise, no energy consumption of clean energy solar battery, has also received strong support from the people. The mainstream but ignore the high pollution behind the glossy surface of solar cell production process, high energy consumption problem.

雙登蓄電池在生產過程中的高污染：現太陽能電池90%為晶體硅電池，其原材料為多晶硅，由金屬硅(工業硅)提純而來，目前國內均采用化學法(改良西門子法)：先將金屬硅轉變為三氯氫硅，再進行分餾和精餾提純，得到高純度的三氯氫硅(具有毒性、腐蝕性和易爆炸)后，最終由氫氣還原而成；這一過程中只有約25%的三氯氫硅傳化成多晶硅，其余基本直接排放；而污染最嚴重的，則是在還原過程中產生的副產品——四氯化硅(一種腐蝕性極強、難以保存的有毒液體，具有急毒性。由于四氯化硅不能自然降解，如果將四氯化硅傾倒或掩埋，水體將會受到嚴重污染，土地會變成不毛之地)。
High pollution in the production process of the solar battery: 90% solar cells for crystalline silicon solar cell, its raw material is polysilicon, silicon (silicon) by metal purification, currently adopts chemical method (improved SIEMENS method): first silicon metal into trichlorosilane, then fractionation and distillation purification, get high purity trichlorosilane (toxic, corrosive and explosive), and ultimately by the hydrogen reduction; this process is only about 25% of the trichlorosilane converted into polysilicon, the direct discharge; and the most serious pollution, is produced as a by-product in the reduction process of silicon tetrachloride (a - four corrosion Extremely strong, difficult to preserve toxic liquid, with acute toxicity. Because four silicon chloride can not be natural degradation, if the dumping or burial of silicon tetrachloride, water will be seriously polluted, the land will become barren land in four

這還不包括大量氯氣等其它易燃易爆有毒氣體。 每生產1KW雙登電池板需耗費10Kg多晶硅，產生80Kg以上四氯化硅。而國內能通過氫化還原閉環工藝循環減小四氯化硅排放的僅有一家；而即使通過氫化還原閉環工藝循環，四氯化硅的排放仍到達50%；四氯化硅雖然也是化工原料，但下游的化工廠消化十分有限。國內絕大多數多晶硅生產廠家的四氯化硅少部分以低價賣給下游廠家，一部分存儲，一部分則偷偷掩埋。 這還不包括硅片后期處理的其它輔料。如制絨過程中用到的各種強酸強堿溶液、擴散使用的三氯氧磷、PECVD中使用的硅烷等，這些輔材的消耗不比主材料少。
This does not include a lot of chlorine and other flammable toxic gases. The production of 1KW solar panels cost 10Kg 80Kg produced more than four polysilicon, silicon tetrachloride. Domestic through hydrogenation of closed loop process cycle four reduction of silicon chloride emissions only one; and even through the hydrogen reduction process of closed-loop circulation, four silicon tetrachloride emissions reached 50%; four although silicon tetrachloride is the chemical raw materials, but the downstream chemical plant digestion is very limited. The vast majority of domestic polysilicon silicon tetrachloride four manufacturers a few sold to downstream manufacturers at a low price, a part of the storage part, secretly buried. This does not include the wafer after Other accessories such as various processing period. The strong acid and alkali solution used for cotton in the process of diffusion of three phosphorus oxychloride used, the use of PECVD in the silane, the auxiliary material is less than the main consumption.

雙登蓄電池還存在高能耗問題：硅石冶煉為金屬硅、金屬硅提純為多晶硅、多晶硅片處理需要耗費大量的電能，主要集中在硅石冶煉、多晶硅的鑄錠和擴散這幾個流程；每生產1KW雙登電池板需要耗費5800-6000度電(國內平均數)。我們可以這樣計算：按平均光照時間4小時/天，太陽能電池是壽命為15至20年(按20年)，1KW雙登電池總的發電量為4x365x20=29200KW?h；與耗掉的6000度電相比，其電能再生比只有4.87，這還沒有算上光照效率以及逆變電源的損耗和控制電路的損耗；遠遠低于水電和風電。如果再加上超白玻璃、鋁合金、鋼材、電纜等輔件，其電能再生比是相當低的。
The solar battery has high energy consumption problem: silica smelting metal silicon, silicon metal purification of polysilicon, polysilicon processing requires a lot of energy, mainly concentrated in the silica smelting, polycrystalline silicon ingot and the diffusion process; the production of 1KW solar panels need to spend 5800-6000 of electricity (national average). Can be calculated according to the average illumination time is 4 hours / day, solar cell is the life of 15 to 20 years (20 years), the total generating capacity of 1KW solar cell is 4x365x20=29200KW? H; compared with 6000 of electricity consumed, the The power regeneration ratio of only 4.87, which is not even counting the light efficiency and loss and control circuit of inverter power source; far less than hydropower and wind power. If coupled with ultra white glass, Aluminum Alloy, steel cable and other accessories, the energy regeneration ratio is rather low.

雖然目前我國雙登蓄電池真正用在國內的還比較少，但是太陽能電池的普及已經是發展的必然結果，我們要面對污染問題需要技術的改進，做到真正的節能環保才行。
Although China's solar battery really used in domestic is still relatively small, but the popularity of solar cells is the inevitable result of the development, we have to face the problems to improve pollution technology, energy saving and environmental protection do the real job.
