Abstract Scope |
The oxide/nitride passivation and flip-chip package technology was developed for the perovskite solar cells. The heat resulted from the physical vapor deposition would decompose the active perovskite layer and degrade the efficiency of the perovskite solar cells down by more than 45%. Remarkably, with Si-nitride passivation processed by plasma-enhanced vapor deposition, the efficiency of the perovskite solar cell only decays about 9.1 %. It should be because that the plasma-enhanced vapor deposition causes much less external energy on the perovskite solar cell. Using the exponential efficiency-decay curves of the flip-chip packaged perovskite solar cells, the characteristic time of the reliability-tested solar cell can be calculated to be 145.8 hours, 390.7 hours, and 4864 hours for air ambient, glove chamber, and water ambient tests, respectively. We concluded that the concentration of O2(g) in the reliability test ambient is the root-cause for the efficiency degradation of the perovskite solar cells. |
