The potential of tandem solar cells combining two chalcopyrite absorbers is evaluated using numerical modeling based on an exhaustive set experimental parameters, offering a high degree confidence in the values reported herein. simple yet reliable approach used here combines transfer matrix‐based optical model wide bandgap CIGSe top subcell as input for 1D electrical reference narrow bottom cel...

We evaluated methods aimed at improving the performance of full-cell including: i) Presodiating HC by discharging to 0.1 V in half-cell; ii) contacting with Na metal; iii) Activating low current charging a rate C/20 initially, iv) Constant cutoff voltage 3.95 then hold for 6 hours. The results showed that cell being charged density did not exhibit feasible work while (iv) displayed an improveme...
