Global Head of photovoltaic sector. TÜV SÜD is a leading global renewable energy testing, certification, inspection, training and knowledge service provider. Robert Puto as we will explain below why the new generation of solar panel
is expected to revolutionize the world's energy production.
It is widely considered the future of energy is renewable. The face of declining commodity, endless supply of energy, after all, show an attractive prospect. The energy should also be clean, safe, than the average energy generator easier to maintain, and produces little or no harmful wastes. In the field of renewable energy, solar energy because of its huge development potential to the fore. For example, the sun to the earth through the atmosphere annually transported up to 3.85 million joules of energy, the energy consumed by humans is about 7900 times. From here we can see that as long as they get 10% of the solar energy, it can completely replace all fossil fuels on the planet. In addition, solar energy, or no noise, and can remotely transmit energy, such as through the earth-orbiting satellites, barren deserts and mountains and so on.
However, the current solar panel (photovoltaic systems) energy generated only 0.1% of global electricity consumption. Why is this? The main reason is because the photovoltaic (PV) technology and is still expensive compared to fossil fuels, not only can not be used on cloudy days, but also need a large area to produce enough electricity. For example, currently the world's largest solar power plant covers an area of over 10 square miles in one (16.9 square kilometers), which produces enough electricity to power 200,000 homes. This data is indeed sigh. However, some experts believe that if the use of current technology to power the United States, the side length of the power station will require about 100 miles (160.9 kilometers).
However, the good news is, engineers, researchers and scholars continue to work day and night, trying to find a better solution, and in some countries have achieved grid parity (the same price or market power, namely photovoltaic electricity generated and both fell There are commercially made grid tariff equivalent). In large and small projects, and gradually achieve grid parity will continue to improve photovoltaic technology commercially more viable - this is a critical success factor.
TÜV SÜD global PV sector to some large renewable energy projects end to end testing, inspection, examination and certification services. As global head of the department, I am honored to monitor, assist and urged implementation of these projects. For example, my team and I not only partners with manufacturers of solar panels china
for testing and certification, while helping the operator (contractor, installation companies and importers) review of the supplier or OEM (original equipment manufacturer) facility, including the ready to be shipped to the installation site for pre-shipment inspection of goods and so on. In addition, from the research and development stage on the way through the testing and certification of the PV industry to provide support, including extended test project to provide a higher standard than the existing degree of confidence and strengthened new product "bankability."
Following introduction of two revolutionary concepts being developed, these two concepts will eventually help to play the potential of solar panels, according to the International Energy Agency (IEA) is expected, solar energy will in less than 20 years to occupy the world's energy Demand 5% 4900% higher than at present.
A third generation photovoltaic cells
After several years of development, the third generation of photovoltaic cells (included at the molecular level with a variety of semi-conductive properties of the material) has emerged. Its advantages are three. First, the third-generation efficiency of photovoltaic cells may be the first generation (crystalline silica) and second generation (thin film photovoltaic) cells double or even triple, that is, the previously mentioned 10 square miles of the solar plant in several years after the 600,000 families will be able to provide sufficient power, rather than the 200,000 (or 1/3 the size of the power supply).
Second and third generation solar cells using high-throughput lower price printing and coating technology, less energy during the manufacturing and equipment investment is low, than previous generations so greatly reduce the cost. For example, manufacturing the first and second-generation battery to clean indoor environment, and the third generation is not required.
Third, the third-generation photovoltaic cell has flexibility. Specifically, the higher the absorbance to a thickness of a few microns can be, and has a high transparency, therefore, can be screen printed on the window. In this way, we can put the batteries directly in the building. In the future, from the building to the bridge and then to the other, and everything can be a large power plants, solar effortlessly get to meet our growing needs.
