••Solar energy storage and conversion to electrical power generation is demonstrated. There is an urgent need for alternative compact technologies that can derive and store energy f. From the Industrial Revolution to 2018, the global average temperature increased by 1°C as a result of human activities and may hit 1.5°C as early as 2030, as warned by the United Nation. Solar energy storage propertiesMOST systems can function in both liquid and film forms, which can be tailored toward different applications.21,38, 39, 40, 41, 42, 43, 44, 4.

In this paper, we demonstrate a compact, chip-based device that allows for direct storage of solar energy as chemical energy that is released in the form of heat on demand and then converted into electrical energy in a controlled way.
What is solar energy storage?
Solar energy storage is an emerging technology which can promote the solar energy as the primary source of electricity.
Why do we need a solar energy storage system?
The global shift from fossil fuels to silicon-based solar cells brings new challenges due to intermittent solar output and fluctuating energy demand, emphasizing the need for effective energy storage.
Can solar energy be stored as chemical energy?
Herein, it was demonstrated that up to 2.3% of solar energy could be stored as chemical energy. Additionally, the integration of the MOST system with the PV cell resulted in a notable decrease in the cell's surface temperature by approximately 8°C under standard solar irradiation conditions.
Can a molecular solar thermal system be combined with a PV cell?
This paper proposes a hybrid device combining a molecular solar thermal (MOST) energy storage system with PV cell. The MOST system, made of elements like carbon, hydrogen, oxygen, fluorine, and nitrogen, avoids the need for rare materials.
How does a molecular solar thermal system work?
This layer employs a molecular solar thermal (MOST) energy storage system to convert and store high-energy photons—typically underutilized by solar cells due to thermalization losses—into chemical energy. Simultaneously, it effectively cools the PV cell through both optical effects and thermal conductivity.
