SOLAR ENERGY TECHNOLOGY IN SRI LANKA

Solar Energy Technology in Sri Lanka

Overview

Energy radiated from the Sun is equivalent to a million billion 100 gigawatt power stations. Some of this energy reaches the Earth at a rate of 1 kW m-2, but technology has only succeeded in tapping a tiny fraction of this energy to date.

Purpose

The main purpose of the research is to understand to innovation diffusion theory and provide policy recommendations for agencies promoting solar energy in developing countries. sunlight falling on the Earth consists of ultra violet (UV), visible and infra-red (heat) radiation and all renewable energy sources (hydro, wind, waves, biomass etc.) arise due to the primary solar energy. (Panicker, Knaster 2002)

Evaluation

Traditionally, solar radiation is exploited using two different methods. Heat energy is absorbed by dark surfaces and used to produce hot water. This method is comparatively low-tech and the technology is known as “Solar Thermal Technology”. In the second method, (Mceachern & Hanson 2008) UV and visible light (photons) are converted directly into electricity (Volts). Since the photons are used to produce voltages, this method is conveniently defined as “Photo-Voltaic (PV) Technology”. (Dharmadasa 2009) The PV effect was discovered by a French Scientist, Edmund Becquerel in 1839, when he was 19 years old. Edmund may have learned this from watching his father, Cesar, known as the grandfather of electrochemistry, working with electrodes and electrolytes in his own laboratory.

5 Course Themes region mobility, globalization, nature-culture, relations, cultural landscape

The exhibition pursues questions around the transformative quality of locations and geographies at a time when subjects are no longer bound to one particular place. Rather than focussing on the formation of dislocated subjectivities due to global migration or the participation in virtual world-wide activities, Geography and the Politics of Mobility will look at the way places are being constituted through them. One of the recurring questions will be how the human trajectories and the traffic of signs and visual information form particular cultural and social landscapes and inscribe themselves materially in the terrain.

The diasporic identity as a subject with a history, a concept developed in valuable intellectual and artistic work during the last decade, will no longer serve as a conceptual framework for this new cartography. A theoretical platform that articulates gender, subject, mobility and space, and a visual language, which can speak of a hyper-mobile, capitalized, gendered body needs to be invented. Geographic bodies. Bodies with a travel schedule. Itinerary identities that grind their routes into the land.

The shift from a historical to a geographic discourse in this area has been particularly appreciated by those scholars and cultural producers who are engaged in issues of globalization and migration. When spatial interests in cultural discourses have been largely aimed at cyberspace, urban structures, and the workplace.

Action of a PV Solar Cell

The PV solar energy conversion consists of three main stages; (a) absorption of a major part of the solar spectrum, (b) effective creation of charge carriers (electron-hole pairs) within the PV device and (c) ...
