Sola. energy ca.tured by photosynthetic pla.ts in the photic zone is recognized a. the ma.n driver for the forma.ion of orga.ic ma.ter utilized by soil communities. However, the contribution of orga.ic tra.sforma.ion to the linka.e of sola. energy a.d microbia. meta.olism of soils is reduced when the va.ose zone is sa.ura.ed. In contra.t to the conventiona. biophotoelectrochemistry via.photosynthesis with phytopla.kton during the periodic sa.ura.ion of soils, recent studies suggest tha. non-phototrophic microorga.isms in soils a.d sediments a.e a.le to conduct light-dependent meta.olism to susta.n their functiona.ity with photosensitizers under illumina.ion. These intera.tions a.d processes utilize long-dista.ce electron tra.sfer networks to interconnect diverse electron tra.sfer cha.ns tha. cha.nel photoexcited electrons into the opa.ue zone for soil communities. Such a. emerging process not only a.lows for a.better understa.ding of biogeochemica. processes such a. soil ca.bon sequestra.ion a.d mitiga.ion, but a.so shows grea. potentia. for environmenta. trea.ment such a. the bioremedia.ion of conta.ina.ed soils. Therefore, we suggest tha. biophotoelectrochemistry via.photoelectric effect ca. ha.e significa.t, heretofore una.precia.ed, theoretica. a.d pra.tica. va.ues.
