Closing the green gap of photosystem I with synthetic fluorophores for enhanced photocurrent generation in photobiocathodes

“…[8][9][10] In biohybrid photovoltaics, photoactive biocomponents are connected to arti-cial electrode materials to generate that photocurrent. Successful setups have been achieved with PSI, 1,5,7,[11][12][13][14][15] PSII, 9,[16][17][18][19][20][21] and bacterial reaction centers. 4,8,[22][23][24][25] But likewise, thylakoid membranes [26][27][28] and even whole cells [29][30][31][32] have been deployed effectively.…”

“…As a dened orientation of large photosystems is difficult to achieve, oen redox-active molecules have been used to shuttle electrons. Examples for these mediators are small redox molecules, 5,18,26,30,32,42 redox polymers 17,19,23,27,28,32,34 or different cytochromes. 12,22,27,35,36,45 The renunciation of redox mediators and, a Biosystems Technology, Technical University of Applied Sciences Wildau, Hochschulring 1, 15745 Wildau, Germany.…”

The effect of ultrafine WO3 nanoparticles on the organization of thylakoids enriched in photosystem II and energy transfer in photosystem II complexes

“…The combination of inorganic semiconductors/metals and natural photosynthetic isolated antenna complexes and even more complex protein‐lipid‐pigment systems, such as entire photosystems, in biohybrid systems is opening a promising area for new research on water photocatalysis (Badura et al, 2006; Grimme et al, 2008; Ihara et al, 2006; Iwuchukwu et al, 2010; Kato et al, 2013; Kawahara et al, 2020; Li et al, 2016; Miyachi et al, 2017; Nagakawa et al, 2019; Riedel et al, 2019; Tahara et al, 2017; Terasaki et al, 2008; Tian et al, 2021; Utschig et al, 2011; Vittadello et al, 2010; Voloshin et al, 2022; Yehezkeli et al, 2012; Yehezkeli et al, 2014; Zhang & Reisner, 2020). These biohybrids are expected to be environmentally safe and use solar energy with near 100% efficiency.…”

“…It seems evident that a new generation of systems capable of oxidizing water with the efficiency of evolutionarily selected photosystems should be based on natural PSII and n‐semiconductors, which are known for their high stability in aqueous environments over a wide pH range. Most efficient semiconductors absorb below 500 nm, but when combined with PSII and/or external photosynthetic antennas, biohybrid anodes have no such limitations on absorbed sunlight (for review, see: [Gonçalves Silva et al, 2022; Liu et al, 2018; Pang et al, 2018; Voloshin et al, 2022; Zhang & Reisner, 2020]). Previous studies have been limited to photosynthetic systems deposited on non‐functionalized or functionalized surfaces, which limited the density of photosystems that could be attached to and in direct contact with flat electrodes and forced the orientation and packing pattern of the photosystems.…”
