Due to the ever-increasing demand for electrical energy, research on renewable energies has achieved tremendous gains. In this study nature has inspired us by the photosynthetic process and triggered the idea of applying the heart of this process (Photosystem1 (PS1)) as active layer in biobased solid state solar cells. Biophotovoltaic solar cells have many advantages such as low cost production, environmentally friendly, and easy waste management compared with other photovoltaic devices. The fabricated biophotovoltaic solar cells have exhibited an impressive increase in short-circuit current density from the low rate of the microamps per squared centimeter range, concluded by previous studies on PS1-based devices, up to the average value of 0.96 mA·cm^–2. Furthermore, these devices are characterized by average values of open-circuit voltage and fill factor of 0.25 V and 31%, respectively. A power conversion efficiency (PCE) of 0.069% is achieved, which is the highest efficiency reported to date for PS1-based solid state solar cells.

基于多层PS1配合物作为活性层的生物光伏固态太阳能电池的新方法

由于对电能的需求不断增长，可再生能源的研究取得了巨大的成就。在这项研究中，自然界通过光合作用激发了我们的灵感，并触发了将这一过程的核心（Photosystem1（PS1））用作生物基固态太阳能电池中活性层的想法。与其他光伏设备相比，生物光伏太阳能电池具有许多优势，例如低成本生产，环境友好和易于废物管理。以前对基于PS1的设备的研究得出的结论是，从以前每平方厘米范围的微安的低速率开始，人造生物光伏太阳能电池的短路电流密度已显着提高，最高达到0.96 mA·cm ^–2的平均值。。此外，这些器件的特征在于开路电压平均值和填充系数分别为0.25 V和31％。实现了0.069％的功率转换效率（PCE），这是迄今为止报道的基于PS1的固态太阳能电池的最高效率。
