Introduction To Solar PV Technologies
There is a pressing require to accelerate the improvement of sophisticated clean power technologies in order to address the global challenges of energy safety, climate adjust and sustainable improvement. This challenge was
acknowledged by the Ministers from G8 nations, China, India and South Korea, in their meeting in June 2008 in Aomori, Japan where they declared
the wish to have IEA prepare roadmaps to advance revolutionary power technology.
“We will establish an international initiative with the help of the IEA to develop roadmaps for revolutionary technologies and co-operate upon existing and new partnerships, including CCS and sophisticated power technologies. Reaffirming our Heiligendamm commitment to urgently develop, deploy and foster clean power technologies, we recognise and encourage a wide range of policy instruments such as transparent regulatory frameworks, financial and fiscal incentives, and public/private partnerships to foster private sector
investments in new technologies….”
To accomplish this ambitious aim, the IEA has undertaken an effort to develop a series of global technologies roadmaps covering 19 technologies.
These technologies are divided amongst demand side and supply side technologies. Our overall aim is to advance global development and uptake of essential technologies to reach a 50% CO2 emission reduction by 2050 by obtaining the IEA top the improvement of power technologies roadmaps beneath international guidance and in close consultation with business. The roadmaps will allow governments, industry and economic partners to recognize measures needed and implement measures to accelerate essential technology improvement and uptake.
This procedure starts with supplying a clear definition and elements required for every roadmap. The IEA has defined its global technologies roadmap accordingly:
“… a dynamic set of technical, policy, legal, monetary, market and organisational needs identified by the stakeholders involved in its improvement. The work shall lead to enhanced and enhanced sharing and collaboration of all connected technologies-certain RDD&D information amongst participants. The objective is to accelerate the general RDD&D approach in order to deliver an earlier uptake of the distinct technologies into the marketplace.”
Every single roadmap identifies major barriers, possibilities, and policy measures for policy makers and industry and monetary partners to accelerate RDD&D efforts for specific clean technologies on both a national and international level.
The rationale for PV
Solar power is the most abundant power resource on earth. The solar power that hits the earth’s surface in one particular hour is about the same as the amount consumed by all human activities in a year. Direct conversion of sunlight into electrical energy in PV cells is a single of the 3 main solar active technologies, the two other folks being concentrating solar power (CSP) and solar thermal collectors for heating and cooling (SHC). Nowadays, PV offers .1% of total international electrical energy generation.
However, PV is expanding really quickly due to dramatic cost reductions. PV is a commercially available and reputable technologies with a important potential for extended-term growth in almost all globe regions. In the IEA solar PV roadmap vision, PV is projected to provide five% of global electricity consumption in 2030, rising to 11% in 2050.
Achieving this level of PV electrical energy supply – and the connected, environmental, financial and societal positive aspects – will require much more concerted policy assistance. Sustained, successful and adaptive incentive schemes are needed to aid bridge the gap to PV competitiveness, along with a extended-term concentrate on technology development that advances all types of PV technologies, including commercially accessible systems and emerging and novel technologies.
