Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, a traditional soil amendment which has been used for fertility improvement and contaminant remediation, has revealed new vitality in this context. In this review we highlight the huge potential of biochar application in different fields to mitigate as high as 2.56 × 109 t CO2e total greenhouse gas (GHG) emissions per year, accounting for 5.0% of the global GHG emissions. Soil applications of biochar as either a controlled-release fertilizer or an immobilization agent offer improved soil health while simultaneously suppressing the emissions of CH4 and N2O. Non-soil applications of biochar also contribute to carbon neutrality in unique ways. Firstly, biochar application as a ruminant feed decreases CH4 emissions via physical sorption and enhanced activities of methanotrophs. Secondly, biochar can be used as a green catalyst for biorefinery. Besides, biochar as an additive to Portland cement and low impact development (LID) infrastructure lowers the carbon footprint and builds resilience to climate change. Furthermore, biochar can be used as novel batteries and supercapacitors for energy storage purposes. Finally, the high CO2 adsorption capacity makes it possible for biochar being used as a sorbent for carbon capture, utilization, and storage (CCUS). We advocate that future research should further explore the effectiveness of biochar systems for climate change mitigation in large scale applications, and assess the economic and social viability of local biochar systems to combat climate change.

Perovskite‐based solar cells (PSCs) are some of the most promising devices for capturing photovoltaic energy. Efficiency has increased from single digits to a certified 25.7%, an unprecedented improvement for any solar cell technology. Incorporating carbon materials into perovskite solar cells promises to be revolutionary in the solar cell field by increasing stability, decreasing manufacturing costs, and making them attractive for commercialization. Here, an overview of the advances in carbon‐based perovskite solar cells (C–PSCs) that incorporate different carbon materials as back contact on different device architectures is presented. An overview of PSC architectures and high‐ and low‐temperature C–PSCs is provided. Additionally, recent advances in the main carbon materials applied in the field, such as graphene, carbon nanotubes, carbon dots, and biocarbon, are presented. Finally, a summary of carbon materials applied to C–PSCs is provided.

“…The carbon nanofibers obtained at 1500 °C exhibited a higher specific surface area of 941 m 2 g -1 , which exhibited better performance as a counter electrode in DSSC with a photoelectric conversion efficiency of 7.60 % and it is almost equal to that of traditional Pt counter electrode (7.67 %). Tiihonen and this team effectively converted the brewery residues into activated biocarbon materials by employing hydrothermal carbonization and KOH mediated chemical activation processes [79]. The obtained activated biocarbon showed a specific surface area of 2190 m 2 g -1 and was explored as the counter electrode in DSSC.…”

To meet the ever‐increasing demand for solar energy conversion, the exploration of new materials that improve energy and cost efficiency is great significance. Particularly in dye‐sensitized solar cells, extensive efforts have been made to substitute the traditional metal‐based components with various carbon materials. As the result, carbon materials such as carbon dots, carbon nanotubes, grapheme, and porous carbon materials are explored for their components, which are traditionally derived from fossil resources. Recently these carbon materials are widely synthesized or derived from renewable biomasses and getting important in solar energy conversion due to their similar structural, physicochemical, morphological, and functional features of above stated traditional carbon materials. The utilization of these biocarbon materials offers numerous environmental and economic benefits over traditional carbon materials and creates a new pathway towards a sustainable future. Thus, this review summarizes the recent exploration of biocarbon materials in dye‐sensitized solar cells and discusses their emerging opportunities.
