The recent dramatic rise in power conversion efficiencies (PCE) of perovskite solar cells has triggered intense research worldwide. However, their practical development is hampered by poor stability and low PCE values with large areas devices. Here, we developed a gas-pumping method to avoid pinholes eliminate local structural defects over film, even for 5 × cm2 modules, the reached 10.6% no significant degradation was found after 140 days outdoor testing. Our approach enables realization...
Zenith tropospheric delay (ZTD) is one of the main error sources in space geodesy. The existing regional or global models, such as Global Pressure and Temperature 3 (GPT3), Tropospheric model, Hopfield, Shanghai Astronomical observatory model have good performance.
