斯坦福研究小组在向转换效率已经达到17%的硅太阳能电池中添加钙钛矿时，他们只测到一个功率很小的增加，达17.9%。
When the Stanford group addedperovskite to silicon solar cells whose efficiency was already 17 percent, forexample, they measured a much smaller increase in power output, to 17.9percent.
但缺陷明显，主要反映效率非常低，它以增加转差功率的消耗来换取转速的降低。
But it is obvious that its efficiency is extremely low, which results from increasing the power consumption. The slower rotational speed, the lower efficiency.
采用两个工作分流，许可通过不产生封闭功率流来增加变速箱效率，研究一个初始解。
By means of two separate phases of operation, an original solution is studied that allows an increase in the transmission efficiency through the generation of a flow without recirculation of power.
