Performance improvement of photovoltaic cells using night radiative cooling technology in a PV/T collector

نویسندگان

چکیده

The solar radiation absorbed by the photovoltaic thermal systems and not transformed into electricity creates a problem that significantly influences reliability efficiency of cells. In order to passively solve this in hot arid climate, night radiative cooling technology was proposed work, where water system cooled circulating collector exploiting technique, it used next day for For aim, mathematical model developed present dynamic behaviour PV/T water-based collector, based on energy balance its components. Then, validated using experimental data available literature study effect glazing masse flow rate performance. main result indicates method reduces daily temperature cells 3–5 °C which improves their monthly gain electrical 5.5%–6.15% compared with conventional collector. Consequently, allows profiting annual potential phenomenon saved 18.49 kWh as an energy.

Radiative cooling for concentrating photovoltaic systems

Radiative cooling, a unique and uncommon passive cooling method for devices operating outdoors, has recently been demonstrated to be effective for photovoltaic thermal management. In this work, we investigate the effect of radiative cooling as a complement to existing passive cooling methods like convective cooling in a related system with much higher heat loads: a high-concentration photovolta...

Performance analysis of photovoltaic thermal (PVT) water collectors

The electrical and thermal performances of photovoltaic thermal (PVT) water collectors were determined under 500–800 W/m solar radiation levels. At each solar radiation level, mass flow rates ranging from 0.011 kg/s to 0.041 kg/s were introduced. The PVT collectors were tested with respect to PV efficiency, thermal efficiency, and a combination of both (PVT efficiency). The results show that th...

Improving photovoltaic performance through radiative cooling in both terrestrial and extraterrestrial environments.

The method of detailed balance, introduced by Shockley and Queisser, is often used to find an upper theoretical limit for the efficiency of semiconductor pn-junction based photovoltaics. Typically the solar cell is assumed to be at an ambient temperature of 300 K. In this paper, we describe and analyze the use of radiative cooling techniques to lower the solar cell temperature below the ambient...
