Solar energy is one of the main sources of energy; hence, nowadays the government is planning to install more solar stations so that more energy can be derived. The world is spending a lot of money on such big projects and as said by the scientists, extracting electricity from sun is the cheapest way. The amount of energy used every year has been increasing day by day and hence people are using resources that are on the verge of extinction and they will easily disappear if we don’t do anything very quickly. The solar cells that are used in the solar panel have a very special kind of feature as it is based on crystalline silicon which increases the efficiencies up to 23 percent and this is a very good efficiency rate, generated from this kind of source. The cost will eventually fall further with even higher efficiencies of more than 26 percent and through this, we can provide future generations cost-efficient electricity.
An international working group, led by photovoltaics researchers are now planning to reach their extreme goal with a nanostructured sheet, which is a transparent material for the front of the solar cell. Silicon solar cells have been consistently improved over the previous many years and have effectively arrived at an extremely undeniable degree of advancement. Nonetheless, the upsetting impact of recombination happens after the retention of daylight and the photovoltaic age of electrical charge transporters. In this cycle, negative and positive charge transporters that have effectively been created, consolidate and offset each other before they could be utilized for the flow of solar electricity. This impact can be countered by uncommon materials that have extraordinary property passivation.
Our nanostructured layers offer precisely the desired passivation, as said by Malte Köhler, former Ph.D. student and first author from the Jülich Institute for Energy and Climate Research (IEK-5) who has recently received his doctorate. No other approach so far combines these three properties passivation, transparency, conductivity as well as our new design. A prototype of the Jülich TPC solar cell achieved high efficiency of 23.99 percent (+- 0.29 percent) in the laboratory. In addition, the ultra-thin layers are transparent, thus, the incidence of light gets highly reduced and exhibits high electrical conductivity.
