Photosystem I application in biohybrid polymer solar cells

The use of Bio-photonic systems has attracted a lot of attention recently specially in the field of solar energy conversion and photovoltaic materials the use of photosynthetic organs of plants is very promising. The energy conversion in the process of photosynthesis is close to 100% and it's environmental compatibly are the main reasons for why photosynthesis has attracted the attention of energy system designers and researchers. The way of solar energy conversion in photosynthesis indicates a great potential as a fount of renewable energy. Use of the photosynthetic components in photosensors and photovoltaic devices solitarily, has disadvantages such as low extracted current compared to other kinds of photovoltaic materials. Accordingly, for more useful and better application, these photosynthetic components could be used as the optimizer of the other species of photovoltaic materials and solar cells. photosystem1 protein complex, which is the main member of photosynthetic components has maximum absorption spectrum wavelength at 430nm and 665nm. Therefore, it can be an appropriate complement for polymeric solar cells with their absorption spectrum at the green wavelength region. In this paper we have used the photosysteml protein complex in the inverted polymer solar cell with structure of ITO/P3HT:ICBA/PS1/A1 and positive results have been observed. So that the polymer solar cells efficiency was enhanced from 4.3% to 4.53%. (C) 2018 Author(s).
