Thermal effects in photovoltaik systems

The concept of photovoltaics (PV) has become a key technology in the energy transition as it provides clean and sustainable energy from sunlight. Advances in PV technologies, including new cell concepts and innovative monitoring systems such as the Hall Effect Current Sensor (HCS Analyzer), are helping to further increase the efficiency and cost-effectiveness of photovoltaic systems

Thermal conductivity of porous carbon materials

Porous carbon materials, in particular carbon aerogels, are the focus of current research. These materials are characterized by an extremely low thermal conductivity, which is mainly due to their porous structure and low bulk density.

Glass Transition Temperature

The glass transition temperature Tg is a point on the temperature scale at which a polymer or glass changes into a rubbery, viscous state. However, this is not the same as the melting point.

How does a pushrod dilatometer work?

A dilatometer is a measuring device for recording the thermal expansion of a material sample. The thermal expansion coefficient (CTE = Coefficient of Thermal Expansion) is calculated from the measurement results.

Crystallization and recrystallization of polymers

The properties of solids depend to a large extent on the arrangement of the particles (atoms and molecules) that make up the substances. If the arrangement is random, the substances are amorphous. In crystalline substances, the particles are arranged at regular intervals and in a fixed pattern.

Curing in thermal analysis

Materials that are processed in a liquid aggregate state generally require a certain amount of time to harden.
