Dye-Sensitized Solar Cell (DSSC) in Developing Countries

Introduction

There is a dire need for reducing the demand of energy. The consumption of energy has increased and is causing a lot of difficulties for the environment. Energy that has been used and consumed today should be saved for future use because if it is wasted, we will not be left with any energy for the future. The decrease in energy demand can be done in a lot many ways.

The first way to reduce the energy demand is to make ensure a eco friendly and sustainable environment. The concept of sustainable development, eco friendly environment reflects a growing awareness of the contradiction between developments can occur, primarily understood as economic growth and improving the material standard of living, and the ecological and social development that can last over time. This awareness of the human, natural and environmental development and progress has come to change the attitude of indifference or justification about it prevailed for a long time. The idea of economic growth without limits and towards which everything could sacrifice came to be replaced by an awareness of these limits and the importance of creating conditions that enable long-term well-being for present generations that is not made ??to price of a threat or deterioration of the living future of humanity.

Sustainable and Eco-Friendly Communities

Sustainable development is accepted solely on environmental issues. More broadly, sustainable development policies affect three areas: economic, environmental and social. In support of this, several United Nations texts, including the Final Document of the World Summit in 2005, refer to the three components of sustainable development, which are economic development, social development and protection of environment, such as "interdependent and mutually reinforcing each other (Gratzel & O'Regan, 1991)."

There are many ways of building efficient buildings; however, one of them is the building of Zero Carbon Homes. The Zero-carbon house is the house that does not pollute, or rather one that has low emissions of carbon dioxide CO2 in relation to a house tradition. In the UK, 21 million residences are accountable for CO2 emissions that are 27%. The government hopes to reduce to 60% for 2050. When we talk about these issues we refer to the CO2 produced by manufacturing and transporting building materials produced to generate the electricity consumed in homes, burning gas for heating, the product of burning garbage, etc. The zero-carbon is the house that produces as much energy as it consumes, with solar panels to produce hot water and electricity, wind turbines, biomass boiler. These homes are being built in UK: Brixton, South London, Leicester and East Middlands; by private developers committed to building the environment (Gratzel, 2004).

These zero-carbon houses will produce less than half of CO2 emissions than a traditional home, will cost 30% more for the technology incorporated: solar panels, wind turbines, biomass boiler, etc., but could be out of reach young people or those who buy a first home. The British government's proposal is that, by 2016 all ...
