6 FAQs about [Artificial solar power generation in the absence of oxygen]

What are artificial solar energy technologies?

Artificial solar energy technologies mostly rely on purely inorganic materials, such as silicon and perovskite photovoltaic cells, for power generation 4. These systems can be coupled to electrocatalysts (often made from non-abundant elements) to perform redox reactions and chemical transformations 5, 6.

What is 'artificial photosynthesis'?

This field of research, called “artificial photosynthesis,” is currently the subject of intense interest, driven by the aim of converting solar energy into the carbon-free fuel hydrogen through the light-driven water splitting.

How do artificial photosynthesis devices use solar energy?

Artificial photosynthesis devices involving semiconductors can absorb solar energy and store it by converting in the form of chemical energy which can be used later.

How do engineered algae produce energy?

The engineered algae exhibit bioelectrogenesis, en route to energy storage in hydrogen. Notably, fuel formation requires no additives or external bias other than CO 2 and sunlight. The cellular power stations autoregulate the oxygen level during artificial photosynthesis, granting immediate utility of the photosynthetic hydrogen without separation.

Can solar energy be converted into chemical energy?

Conversion of solar energy into chemical energy through the light-driven water splitting indeed generates the environmentally benign oxygen gas and hydrogen, a carbon-free fuel with the highest energy output relative to molecular weight.

What is Artificial Photosynthesis System (APS)?

Artificial photosynthesis system (APS) imitates the fundamental process of photosynthesis taking place in organisms for our societal needs. APS captures as well as stores solar energy in the form of fuel rather than glucose and is able to meet both the challenges of being carbon-negative and a source of solar fuel (Figure 1).
