This paper explores the potential vulnerability of solar energy systems to future extreme event risks as a consequence of climate change. We describe the three main technologies likely to be used to harness sunlight—thermal heating, photovoltaic (PV), and concentrating solar power (CSP)—and identify critical extreme event vulnerabilities for each one. We then compare these vulnerabilities with ...

A solar trigeneration system, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump unit for heating and cooling, is modelled to forecast the thermal and electric yields of the system. The aim of the trigeneration system is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an urban single family ...

Solar photovoltaics (PV) are emerging as a major alternative energy source. The cost of PV electricity depends on the efficiency of conversion of light to electricity. Despite of steady growth in the efficiency for several decades, little has been achieved to reduce the impact of real-world operating temperatures on this efficiency. Here we demonstrate a highly efficient cooling solution to the...

In this study, efficiency of water-type photovoltaic/thermal (PV/T) modules that convert solar energy into both electrical and thermal were investigated. By using identical photovoltaic (PV) cells, one PV module five PV/T differed in structure with different diameters, amount layout absorber tubes, type sheets fabricated lamination technique.

Recent work has proposed that hybridization of residential-scale cogeneration with roof-mounted solar photovoltaic (PV) arrays can increase the PV penetration level in ideal situations by a factor of five. In regions where there is a significant cooling load PV-cogen hybrid systems could be coupled to an absorption chiller to utilize waste heat from the cogen unit. In order to investigate reali...

Radiative cooling is a method to control the temperature of semiconductor devices used in concentrated photovoltaics (CPV) and solar thermophotovoltaics (TPV). We find that it can increase the operating voltage and efficiency up to 5%. OCIS Codes: 030.5620 (Radiative transfer); 350.6050 (Solar energy); 350.4238 (Nanophotonics and photonic crystals) 1. Radiative Cooling for Concentrating Solar P...

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...

Abstract The photovoltaic module (PV) consists of many cells made silicon that lose their properties with an increased temperature. Increasing cell temperature represents intrinsic problem causes a drop in the open-circuit voltage PV module, thus affecting its performance. present work investigates using evaporating cooling as passive technique to absorb generated heat from and lower by cotton ...
