We have a new PSI Review Article!
Our Photosystem I subgroup (Kody, Dilek, Chris and Jennings Lab collaborator Josh Passantino) were asked to review to the current state of PSI-based photovoltaics and the challenges the field faces for improvement of solar energy conversion.
They did a wonderful job and we are very proud! The title, abstract and link are listed below. If you are interested in this type of work please contact us.

Isolated photosystem I (PSI) has been integrated into numerous technologies for solar energy conversion. Interest in PSI is a consequence of its high internal quantum efficiency, thermal stability, ease of extraction, and adaptability. While there has been success in improving performance to elevate PSI biohybrid technologies toward a practical realm, the stability of PSI bioelectrodes is also of critical importance. Commercial solar energy conversion technologies are expected to achieve lifetimes of the order of ten years; however, many research-scale PSI bioelectrodes have only been tested for tens of days. Key areas affecting PSI bioelectrode stability include the effects of reactive oxygen species, immobilization strategies, and the environment within solid-state PSI biohybrid photovoltaics. At the current state, further investigation of long-term stability is necessary in enabling the development of PSI bioelectrodes for both photoelectrochemical cells and solid-state biohybrid photovoltaics.
