High Efficient Solar Battery Has Good Foreground
The foreground of use solar to gain power is becoming better,make use of sun light centralization equipment and high efficient solar battery may reduce the cost of solar generating.
CIS film solar battery has good performance,and be called the next generation cheapness solar battery.
The produced solar battery include silicon battery,arsenide cadmium
battery,telluride cadmium battery,arsenide-telluride battery and phosphide indium battery et. The silicon battery is the most opportune,it is made of silicon,the technology is easy than normal transistor. The silicon battery change solar into DC directly,the transformation efficiency is 9-12 percents,it means that 1 cm2 silicon battery can generate 10 mw power under the condition of sun light intension is 1kw/m2.
The silicon battery is the main power equipment of satellite and airship,and on the ground,it is use as especial electrical source coordinating with storage cell.
使用太阳能发电的前景正变得日益光明起来,利用阳光集中设备和高效的硒电池有可能降低太阳能发电的成本,使其达到具有竞争力的水平。
铜铟硒(CIS)薄膜太阳电池性能优异,被国际上称为下一代的廉价太阳能电池。
现在制成的太阳电池有硅电池、砷化镓电池、硫化镉电池、碲化镉电池、硅—碲化镉电池、磷化铟电池等多种,而以硅电池发展得最为成熟。硅太阳电池是用地球上富有的元素硅制造的,其工艺比一般晶体管的制造工艺简单。硅太阳电池能把太阳能直接转变成直流电。大量生产的硅电池,其光—电转化效率一般为9~12%,也就是在地面阳光强度为1千瓦/米2的条件下,每平方厘米的硅电池,能发出10毫瓦的电能。
目前,硅太阳电池是人造卫星、宇宙飞船上的主要能源装置,在地面上则与蓄电池配合,作为特殊电源使用。
