Abstract. Solar energy is abundant all over the world, but to be useful, the energy received must either be transformed to electricity, heat or latent chemical energy.

Potassium metal batteries (PMBs) have become a paramount alternative energy storage technology to lithium-ion batteries, due to their low cost and potential energy density. However, uncontrolled dendrite growth interferes with the stability of the interfacial anode, leading to significant capacity degradation and safety hazards.
In comparison, MOlecular solar thermal energy STorage (MOST) materials [10], [11], [12] can offer a higher energy density than PCMs without influencing the visible transmittance of light. Unlike sensible and latent heat storage materials, which are charged with heat, the MOST molecules absorb solar irradiation, i.e., photons.
