Biomass-derived carbon electrodes for supercapacitors and hybrid solar cells: towards sustainable photo-supercapacitors

“…Only 28 reports are published on the application of ACs extracted from biomass waste as counter-electrode for DSCs and the highest results of PCE are summarized in Table 2. [104][105][106][107][108][109][110][111][112][113] Highly conductive porous AC can be obtained from biomass with the use of simple activation methods already discussed in the first section and the resulting materials applied as low-cost counter-electrodes for high performance DSCs. notes: meso-porous, mp-; activated carbon, AC.…”

“…Fish waste is also abundant in nitrogen, sulfur, phosphorous elements, and contains high content of carbon. 110,42 Ma et al achieved the carbonization of fish waste and the resulting material was used as counterelectrode in DSCs. 110 Using a simple carbonization method and KOH as activation agent, the resulting carbon material showed a large surface area (2933 m 2 g -1 ) with high catalytic activity.…”
