原始和退火体异质结太阳电池中的极化子极化
Polaron Recombination in Pristine and Annealed Bulk Heterojunction Solar Cells
摘要：
利用光CELIV技术研究了P3HT：PCBM太阳电池中光生极化子的主要损失机制。对于原始的和退火的设备，我们发现，实验数据可以解释的双分子复合率减少了约10（原始）和25（退火）的因素相比，朗之万理论。借助于宏观器件模型，我们讨论了降低损耗率对聚合物：富勒烯太阳能电池特性的影响。
英文摘要：
The major loss mechanism of photogenerated polarons was investigated in P3HT:PCBM solar cells by the photo-CELIV technique. For pristine and annealed devices, we find that the experimental data can be explained by a bimolecular recombination rate reduced by a factor of about ten (pristine) and 25 (annealed) as compared to Langevin theory. Aided by a macroscopic device model, we discuss the implications of the lowered loss rate on the characteristics of polymer:fullerene solar cells.
