问题是热能转化系统需要更高的温度，而太阳能电池的效率在高温下迅速降低。

The problem has been that high temperatures are necessary to power heat-based conversion systems, yet solar cell efficiency rapidly decreases at higher temperatures.

该团队将尝试探测电子传导的电流并制作基于热电子传导的太阳能电池板，即使其能量转化效率仍然很低。

The team will now attempt to detect the transferred electrons as current and make solar cells that exploit hot electron transfer, even if the efficiency is still low.

今后的步骤将涉及对天然藻类进一步筛选，以找到那些在利用太阳能、将二氧化碳转化为油方面效率特别高的品种。

The next steps will involve further screening of natural algae to find strains that are particularly efficient at using energy from sunlight to convert carbon dioxide into oils.
