Learn MoreOwing to such a fine-tuned donor-acceptor microstructure network, the photovoltaic performance of the H 2 Chl bio-additive-based OSC achieves a 17.30% PCE and ZnChl-based device obtains an efficiency of 16.61%, which is much higher than that of the control device with a 15.97% PCE. The result proves the feasibility of introducing …
Learn MoreMore efficient solar cells will certainly help close that gap, and Case is keen to emphasize that 29.52% is "nowhere near" the maximum PCE for silicon/perovskite tandem cells. However, the time available for installation is short enough, and the required number of panels large enough, that other considerations also play a role.
