Wide-bandgap (WBG) perovskite solar cells have attracted considerable interest for their potential applications in tandem cells. However, the predominant obstacles impeding widespread adoption are substantial open-circuit voltage (V
The phase adaptive stabilization system (PASS), functioning as an optics of radio frequency (RF), is a key technology for achieving the next generation single-dish submillimeter-wave (sub-mm) telescopes. However, PASS has not yet achieved closed loop measurement and correction in real-time. Furthermore, presence systematic errors hinders system's practical implementation. Here we have successfully established closed-loop both laboratory outfield. been experimentally proven to be sufficiently...

Intermediate between the prestellar and Class 0 protostellar phases, first core is a quasi-equilibrium hydrostatic object with short lifetime an extremely low luminosity. Recent MHD simulations suggest that can even drive molecular outflow before formation of second (i.e., protostar). Using Submillimeter Array Spitzer Space Telescope, we present high angular resolution observations towards embedded dense IRS2E in L1448. We find source L1448 not visible sensitive infrared images (at...
