To fulfill the global demand of fuel, the generation of fuel must be from renewable sources of energy such as solar radiation. Halide-based perovskite (HLP) is one of the materials which utilizes maximum of irradiant solar radiation and can drive water splitting and CO₂ reduction processes in an efficient way. The HLPs are generally used in the form of perovskite solar cells or as such to enable these reactions. In this chapter, we provide the basic understanding for the utilization of HLP for water splitting and CO2 reduction to generate valuable chemical energy using HLP-based solar cell devices. The different strategies such as photocatalysis using HLP particles, photoelectrode using HLP in photoelectrocatalysis and photovoltaic cell driven electrochemical process for generation of chemical energy are discussed in detail. Further modifications in the strategies of utilization of HLP itself and perovskite solar cells for chemical fuel generation are presented. In this chapter, we present the discussion on the utilization of HLP in its usual form and solar cell devices fabricated using HLP for chemical energy generation.

摘要

To fulfill the global demand of fuel, the generation of fuel must be from renewable sources of energy such as solar radiation. Halide-based perovskite (HLP) is one of the materials which utilizes maximum of irradiant solar radiation and can drive water splitting and CO₂ reduction processes in an efficient way. The HLPs are generally used in the form of perovskite solar cells or as such to enable these reactions. In this chapter, we provide the basic understanding for the utilization of HLP for water splitting and CO2 reduction to generate valuable chemical energy using HLP-based solar cell devices. The different strategies such as photocatalysis using HLP particles, photoelectrode using HLP in photoelectrocatalysis and photovoltaic cell driven electrochemical process for generation of chemical energy are discussed in detail. Further modifications in the strategies of utilization of HLP itself and perovskite solar cells for chemical fuel generation are presented. In this chapter, we present the discussion on the utilization of HLP in its usual form and solar cell devices fabricated using HLP for chemical energy generation.
