It is possible to harvest energy from Earth's thermal infrared emission into outer space. We calculate the thermodynamic limit for the amount of power available, and as a case study, we plot how this limit varies daily and seasonally in a location in Oklahoma. We discuss two possible ways to make such an emissive energy harvester (EEH): A thermal EEH (analogous to solar thermal power generation...
This paper compares two solar systems, an actual building integrated, photovoltaic roof (BIPV) and a notional solar thermal system for a residential block in London, UK. The carbon payback for the solar thermal system is 2 years, the BIPV system has a carbon payback of 6 years. Simple economic payback times for both systems are more than 50 years. Calculations considering the current UK energy ...
Passive design responds to improve indoor thermal comfort and minimize the energy consumption. The present research analyzed the how efficiently passive solar technologies generate heating and cooling and provide the system integration for domestic applications. In addition to this, the aim of this study is to increase the efficiency of solar systems system with integration some innovation and ...
The autonomous energetic system is for a residential building and it has as primary sources exclusively renewable resources (biomass and solar energy). For obtaining electrical energy, photovoltaic sources and a Stirling engine are used. They operate simultaneously in 1:3 ratio – electrical/thermal energy. Solar collectors and a pellet boiler are used to cover the necessary of thermal energy. T...
In this paper, the electrical consumption of a Research Center Building is derived of the bills, Then with defining of fuzzy Bus Thermal Coefficient objective function for heating, the amount of available heat selling to Research Center Building consumer that is produced by Biomass Solar Hybrid Source is calculated. With the capacity determination of Biomass Solar Hybrid Source to provide Therm...
The conversion of sunlight into electricity has been dominated by photovoltaic and solar thermal power generation. Photovoltaic cells are deployed widely, mostly as flat panels, whereas solar thermal electricity generation relying on optical concentrators and mechanical heat engines is only seen in large-scale power plants. Here we demonstrate a promising flat-panel solar thermal to electric po...
In this paper, a hybrid photovoltaic-battery-diesel generator system is designed and optimized for a remote islanded electric network in the northwest regions of the country. Considering the hardship of transferring fuel to the region where the system is installed, this study aims to minimize the generator fuel consumption. To evaluate the effectiveness of the proposed system economically, the ...
2,4-Bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphenyl] squaraine (SQ) was employed as a donor material in organic photovoltaic cells based on planar heterojunctions. We studied optical properties of SQ films, and discussed its photovoltaic performance via numerical fitting and simulation on the photovoltaic cells. Exciton diffusion length (LD) in SQ films (4.5 nm) derived from optical simulation ...
