The M13 bacteriophage, a nature‐inspired environmentally friendly biomaterial, is used as a perovskite crystal growth template and a grain boundary passivator in perovskite solar cells. The amino groups and carboxyl groups of amino acids on the M13 bacteriophage surface function as Lewis bases, interacting with the perovskite materials. The M13 bacteriophage‐added perovskite films show a larger grain size and reduced trap‐sites compared with the reference perovskite films. In addition, the existence of the M13 bacteriophage induces light scattering effect, which enhances the light absorption particularly in the long‐wavelength region around 825 nm. Both the passivation effect of the M13 bacteriophage coordinating to the perovskite defect sites and the light scattering effect intensify when the M13 virus‐added perovskite precursor solution is heated at 90 °C prior to the film formation. Heating the solution denatures the M13 bacteriophage by breaking their inter‐ and intra‐molecular bondings. The denatured M13 bacteriophage‐added perovskite solar cells exhibit an efficiency of 20.1% while the reference devices give an efficiency of 17.8%. The great improvement in efficiency comes from all of the three photovoltaic parameters, namely short‐circuit current, open‐circuit voltage, and fill factor, which correspond to the perovskite grain size, trap‐site passivation, and charge transport, respectively.

变性 M13 噬菌体模板钙钛矿太阳能电池表现出高效率

M13噬菌体是一种受自然启发的环保生物材料，在钙钛矿太阳能电池中用作钙钛矿晶体生长模板和晶界钝化剂。 M13噬菌体表面氨基酸的氨基和羧基充当路易斯碱，与钙钛矿材料相互作用。与参考钙钛矿薄膜相比，添加 M13 噬菌体的钙钛矿薄膜表现出更大的晶粒尺寸和更少的陷阱位点。此外，M13噬菌体的存在会引起光散射效应，从而增强光吸收，特别是在825 nm左右的长波长区域。当在成膜前将添加 M13 病毒的钙钛矿前体溶液加热至 90°C 时，M13 噬菌体与钙钛矿缺陷位点协调的钝化效应和光散射效应都会增强。加热溶液会破坏 M13 噬菌体的分子间和分子内键，使其变性。添加变性 M13 噬菌体的钙钛矿太阳能电池的效率为 20.1%，而参考器件的效率为 17.8%。效率的巨大提高来自于所有三个光伏参数，即短路电流、开路电压和填充因子，它们分别对应于钙钛矿晶粒尺寸、陷阱位点钝化和电荷传输。
