"high absorption coefficient, 1-step nanocrystal ink instead of layered deposition, reduce cost/ material loss, scalable, overcomes surface defects causing low power conversion efficiency... post-deposition in situ passivation improves surface passivation, yielding nanocrystal ink films with enhanced optoelectronics, with higher power conversion efficiency... 10% efficient... multifunctional molecular agent containing chlorine stabilize/ disperse evenly nanocrystals and  within the solution... extended carrier lifetime"
