Simulation of an active cooling system for low-concentratinag photovoltaic solar cells

open access: yesActa Polytechnica
One of the key challenges of concentrating photovoltaic (CPV) systems is the need for effective thermal management, as the increased solar irradiance significantly raises the operating temperature of solar cells, thereby reducing their efficiency.

Using The Low Concentrated Photovoltaic Module As A Preheater In An Organic Rankine Cycle

open access: yesHittite Journal of Science and Engineering, 2020
I n concentrated photovoltaic thermal CPVT systems, sunlight is directly converted into electricity and during this conversion waste heat is generated on the photovoltaic module. The resulting waste heat can be used for heating the fluids.
