全无机胶体量子点太阳能电池中少数载流子寿命测量
Measureing Minority Carrier Lifetime in All-Inorganic Colloidal Quantum Dot Solar Cells
摘要
Abstract
The accurate measurement of the minority carrier lifetime is of vital significance in research and manufacture of solar cells. Using open circuit voltage decay ( OCVD ) technique with a nanosecond light pulse (pulse width of 8 ns, frequency of 10Hz)as excitation light source we obtained the open-circuit voltage transient response curve of all-inorganic colloidal quantum dot solar cells at different temperatures. Exact minority carrier lifetimes in cells at low (77 K -277 K)and high (277 K ~ 317 K) absolute temperature regions have been obtained as 0.369 jjls and 6. 25xl(T3 jljls.关键词
