| Abstract Scope |
Perovskite solar cells (PSCs) are considered one of the most promising solar energy harvesters because of their high power conversion efficiency (PCE). To increase their PCE even further, additives are used; however, some of these additives pose certain disadvantages. Therefore, the nature-inspired ecofriendly M13 bacteriophage is genetically engineered to maximize its performance as a perovskite crystal growth template and as a passivator for PSCs. The genetic manipulation of the M13 bacteriophage enhances the Lewis coordination between the perovskite materials and virus by amplifying a designated amino acid group. Among the 20 types of amino acids, lysine (Lys or K) exhibits the strongest interaction with the perovskites. The K-type M13 virus-inoculated PSCs yield a PCE of 23.6% in the laboratory. When taken to a national laboratory for verification, this device exhibits a certified forward-and-reverse-bias-combined efficiency (22.3%), which is one of the highest efficiencies reported among biomaterial-based PSCs. |
