采用双真空化学气相沉积法在n+-Si(001)衬底上制备了30层Ge/Si量子点(QDs)薄膜p-i-n太阳电池(SC)。与未加Ge量子点的SC相比,添加Ge量子点的SC在红外区的外量子效率和短路电流密度均有所提高。然而,它们的开路电压和效率下降。p型Ge/Si量子点SC的开路电压在低温下显著恢复,这是由于复合中心的抑制和载流子寿命的延长。
Thin film p-i-n solar cells (SCs) with 30 bilayers undoped or p-type self-assembled Ge/Si quantum dots (QDs) were fabricated on n+-Si(001) substrates by ultrahigh vacuum chemical vapor deposition. Compared with the SCs without Ge QDs, the external quantum efficiency in infrared region and the short-circuit current densities of the SCs with Ge QDs increased. However, their open-circuit voltages and efficiencies decreased. The open circuit voltages of p-type Ge/Si QDs SCs recovered significantly at low temperature, which was due to the suppression of recombination centers and longer carrier lifetime.
