留学论文代写:未来能源生产的可持续措施

当前,全球都在关注不可再生能源。光伏电池在这方面很受欢迎,因为它们能够将阳光转化为电能。光伏安装的数量增加了在当前倍和2012年被认为是100年左右GWp(千瓦)(1)。当前使用PV被看作是依赖于薄膜结构的PV碲化镉、硫化镉在哪里被使用。就经济问题而言,薄膜电池要便宜得多,而且它们的能源回收时间也短得多。然而,薄膜细胞有一个缺点,他们是由稀有元素,如碲。碲是一种稀有金属,其稀有程度可与黄金媲美。其他元素包括铟和镓。在此背景下,钙钛矿基半导体及其在能源效率中的应用被认为具有更高的转换效率。在此背景下,本研究的重点是了解钙钛矿太阳能电池作为未来能源生产的可持续措施。

钙钛矿一词和钙钛矿结构可以互换使用。从技术角度看,钙钛矿是指在乌拉尔山发现的一种矿物。这种钙钛矿结构是与钙钛矿具有相同技术结构的化合物。钙钛矿以钙、氧、钛的形式存在,主要存在于CaTiO3结构中。钙钛矿是通用ABX3的名称。它被发现具有与钙钛矿相同的晶体结构。偏爱钙钛矿太阳能电池的原因是,使用太阳能电池不会产生负面影响。它们的寿命、持续时间和细胞功能还有待证实。没有证据表明它们是有机装置。不建议在钙钛矿化合物中使用铅。因此,只使用了少量的化合物,镉或铅电池被认为是钙钛矿化合物的替代品。应该考虑化合物的光密度。钙钛矿的光密度比硅高。因此,钙钛矿设备需要更厚的收获层。这些被发现会导致制造限制。关键的发展是,前驱体材料的基础上钙钛矿沉积已使用真空沉积。真空加工的材料更容易规模化,在这个过程中,资本成本会变得非常昂贵。有必要使低成本的每瓦钙钛矿太阳能电池具有预期的效率基于其潜力。尽管钙钛矿的使用潜力很大,但生产高效率产品也要付出相当大的资本成本。因此,钙钛矿材料具有很高的重要性,但有必要降低产品的初始资本成本。为了开发一系列钙钛矿产品,过去进行了大量的研究。为了开发出更好的特性,需要更多的技术、制造和测量。

In current times there is a global focus on non-renewable energy sources. Photovoltaic cells are popular in this context because their ability to convert sunlight into electricity. The number of PV installations have increased in current times as and as of the year 2012 is seen to be around 100 GWp (gigawatts) (1). The current usage of PV is seen to be dependent on the thin film structure of PVs where cadmium telluride or cadmium sulfide is being used. In terms of economic issues, the thin film cells are much cheaper and they have an energy payback time which is also much shorter. The thin film cells however have a disadvantage in that they are made of rare elements such as tellurium. Tellurium has a rarity that can be comparable to gold. Other elements that are included are indium and gallium. Given this context the Perovskite based semiconductors and its use in the energy efficiency are seen to present more conversion efficiencies. Given this context, this research is focused on understanding Perovskite solar cells as sustainable measure of energy production for the future.

The term perovskite and the perovskite structure has been used interchangeably. From a technical perspective, perovskite is the name given to the mineral that was found in the Ural mountain. This perovskite structure is the compound that has the same technical structure of the perovskite mineral. Perovskite has been used in the form of calcium, oxygen, titanium and is also found predominately in the CaTiO3 structure. The perovskite is the name that has been given to the generic ABX3. It has been found to have the same crystallographic structure as the mineral perovskite. The reason for the preference towards the perovskite solar cells is that there is no negative known from using the solar cells. Their lifetime duration and function of the cells are yet to be proven. There is no evidence that suggests that they are of organic devices. The use of lead in the perovskite compounds is not recommended. Owing to this, only a small amount of compound has been used and cadmium or lead batteries is considered to be the alternative for the perovskite compounds. There should be a consideration of the optical density of the compounds. The perovskite optical density is found to be higher than that of silicon. Owing to this, the perovskite devices require thicker harvesting layers. These are found to cause fabrication limitation. The key development is that the precursor material for solutions based on the perovskite deposition has been using the vacuum deposited. The vacuum based processing of the materials are easier to scale and the capital cost can become very costly in this process. There is a need to enable a low cost per watt for the perovskite solar cells to have the intended efficiency based on its potentials. Even though there is a high potential for the usage of perovskite, there is also considerable capital costs that are involved for the creation of high efficiency products. Hence, there are high levels of significance for the perovskite materials but there is a need to scale down the initial capital costs of the product. There has been a lot of research that has been undertaken in the past to develop a range of the perovskite products. There is a need for more technology, fabrication and measurement for the development of better characteristics.
