In the present work, we explore in photoanodes of dye‐sensitized solar cell (DSSC) the co‐sensitization of the red protein phycoerythrin extracted from Antarctic algae with spherical silver nanoparticles between 10 and 200 nm and triangular nanoparticles of ~100 nm. We found that the order of addition of the sensitizers matters. Best results achieved for a sequential approach was phycoerythrin used as a dipping solution at the first step and nanoparticles at the second. We found that cell efficiency depends on the protein concentration, although no main differences detected with the nanoparticle shape or size. Our results show an average increase of 25% in the conversion efficiency values in the presence of nanoparticles.

利用银纳米粒子对来自南极资源的共同致敏细胞

在目前的工作中，我们在染料敏化太阳能电池（DSSC）的光阳极中探索从南极藻中提取的红色蛋白藻红蛋白与10到200 nm之间的球形银纳米颗粒和约100 nm的三角形纳米颗粒的共敏化。我们发现敏化剂的添加顺序很重要。顺序方法获得的最佳结果是在第一步中将藻红蛋白用作浸渍溶液，而在第二步中将纳米颗粒用作浸渍溶液。我们发现细胞效率取决于蛋白质浓度，尽管没有检测到与纳米粒子形状或大小的主要差异。我们的结果表明，在存在纳米颗粒的情况下，转化效率值平均提高了25％。
