چکیده
Global energy demand and environmental concerns are the driving force for use of alternative, sustainable, and clean energy sources. Solar energy is the inexhaustible and CO2-emission-free energy source worldwide. The Sun provides 1.4 10 TW power as received on the surface of the Earth and about 3.6 10 TW of this power is usable. In 2012, world power consumption was 17 TW, which is less than 3.6 10 TW. Photovoltaic (PV) cells are the basic element for converting solar energy into electricity. PV cell technologies, energy conversion efficiency, economic analysis, energy policies, environmental impact, various applications, prospects, and progress have been comprehensively reviewed and presented in this paper. This work compiles the latest literature (i.e. journal articles, conference proceedings, and reports, among others) on PV power generation, economic analysis, environmental impact, and policies to increase public awareness. From the review, it was found that PV is an easy way to capture solar energy where PV based power generation has also rapidly increased. & 2014 Elsevier Ltd. All rights reserved.

Factors Affecting Photovoltaic Technology Application in Decentralized Electricity Production in Iran: a Conceptual Framework
Using a variety of solar power plants is one of the solutions governments use to respond to energy and sustainable development needs. While Iran has a strong potential for using solar energy, the application of solar energy, especially through PV technology, has been limited due to the country’s richness of fossil fuels and their low prices. Therefore, it is important to adopt effective strateg...
متن کاملEconomic assessment of renewable power generation based on wind speed and solar radiation in urban regions
Economic evaluation of 12 MW grid-connected wind farms and PV power plants in two regions in Northern Cyprus for electricity generation was investigated. The wind speed, sunshine duration, and solar global radiation characteristics were analyzed using monthly data collected over 17 years (2000-2016) for Girne and nine years (2008-2016) for Lefkoşa, which were measured at various heights. The re...
