In its search for new technologies for solar energy that can produce lower-cost electricity, Smith-Diatom is developing a new way to make dye-sensitive solar cells, in which photons strike light-sensitive dyes. The process uses diatoms, which are unicellular algae that have silicon shells with a complex structure. First, the organic material is removed, and then the shells are coated with a titanium dioxide film that acts as a semiconductor. The diatoms' structure results in more photon activity and thus more efficient production of electricity than with current dye-sensitized solar cells, which in turn lowers the cost.
Which of the following considerations would, if true, most strongly support the hypothesis that the plan, if implemented, will produce low-cost electricity from dye-sensitive solar cells?
- ADiatoms are an important link in oceanic food chains and help cycle carbon dioxide from the atmosphere. 分析该选项
- BThe current cost of electricity produced by dye-sensitive solar cells is roughly three times that of non-solar electricity.分析该选项
- CBecause diatoms occur naturally, no special engineering processes are needed to produce the basic dye-sensitive solar cell structures. 分析该选项
- DDye-sensitive solar cells work somewhat more efficiently in lower light than previous solar cell technologies. 分析该选项
- EThe production of dye-sensitive solar cells primarily uses materials that do not harm the environment. 分析该选项
- 求问这道题为什么不选E啊,不是 more efficient production of electricity可以减少花费么
