This paper proposes a dynamic model of a solar-based micro-cogeneration system called photovoltaic-thermal (PVT) collector to perform a design optimization of the multi-stage PVT system. Micro combined heat
Molecular solar thermal energy storage is a technology based on photoswitchable materials, which allow sunlight to be stored and released as chemical energy on demand. Wang et al. demonstrate a molecular thermal
Thermoelectric micro-generators (μ-TEGs) exhibit several key benefits, making them prime candidates for harvesting any temperature difference between their two exchange surfaces. However, their output power critically depends on the
This chapter introduces various solar thermoelectric technologies including micro-channel heat pipe evacuated tube solar collector incorporated thermoelectric power generation system, solar concentrating thermoelectric generator using the micro-channel heat pipe array, and novel photovoltaic–thermoelectric power generation system.
The generator can produce, as a proof of concept, a power output of up to 0.1 nW (power output per unit volume up to 1.3 W m −3 ). Our results demonstrate that such a molecular thermal power generation system has a high potential to store and transfer solar power into electricity and is thus potentially independent of geographical restrictions.
The EU-funded Innova MicroSolar project has delivered a high-performance, cost-effective concentrating solar power (CSP) system for small-scale, onsite electricity and heat generation. Photovoltaic (PV) systems use sunlight to generate electricity directly via semiconductor-based PV cells.
Here, we report a combination of solution- and neat-film-based molecular solar thermal (MOST) systems, where solar energy can be stored as chemical energy and released as heat, with microfabricated thermoelectric generators to produce electricity when solar radiation is not available.
The integrated solar heat pipe thermoelectric generator module consists of a square channel for the cooling water, a thermoelectric generator, a heat pipe with selective absorbing coating, and an evacuated tube.

Thermoelectric power generation (TEG) is the most effective process that can create electrical current from a thermal gradient directly, based on the Seebeck effect. Solar energy as renewable energy can provide the thermal energy to produce the temperature difference between the hot and cold sides of the thermoelectric device.
