Solar-powered catalytic water-splitting processes can be exploited as a source of electrons and protons to make clean renewable fuels, such as hydrogen, and in the sequestration of CO2 and its conversion into low-carbon energy carriers.
Can solar energy be converted into chemical fuels?
DOI: 10.2533/chimia.2013.155 Abstract Efficiently and inexpensively converting solar energy into chemical fuels is an important goal towards a sustainable energy economy. An integrated tandem cell approach could reasonably convert over 20% of the sun's energy directly into chemical fuels like H2 via water splitting.
How was solar energy converted into chemical energy?
The solar energy was converted into chemical energy by the STEG and electrochemical system. 1. Introduction Energy crisis and environmental issues are attracting increasingly attention in the world due to the excessive consumption of nonrenewable fossil energy, .
How can solar energy be produced?
One of the other well established methods for producing energy from sunlight is the use of photovoltaics, which has been described as the 'art of converting sunlight directly into electricity' . A typical commercially available solar cell can convert roughly 20% of the solar spectrum into electricity.
Can solar panels be used as energy production systems?
Therefore, photosynthesis is the ultimate source of all biomass production. Solar panels have also been recognised as a potential electrical energy production system. By combining two energy production systems one can fully utilise the solar spectrum and light incident on a surface.
Can a light absorber convert solar energy into electric energy?
The key is to explore cost-effective and high-performance light absorber to convert solar energy into thermal energy for applications, such as water heating, water distillation, electricity generation, and so on. As a supplement to PV, the indirect route that converting the solar energy into electric energy via solar thermal process is promising.
Harvesting solar energy to convert CO2 into chem. fuels is a promising technol. to curtail the growing atm. CO2 levels and alleviate the global dependence on fossil fuels; however, the assembly of efficient and robust systems for the selective photoconversion of CO2 without sacrificial reagents and external bias remains a challenge.
