钙钛矿太阳能电池是由一种混合有机化合物构成的,该化合物也具有光活性层。钙钛矿材料通常生产成本较低,由卤化铅制成,易于生产。研究表明,这些元素将使太阳能效率提高3.8%以上,最高可达21%。此外,钙钛矿还被视为更具商业吸引力的投资项目。初创公司投资钙钛矿,太阳能电池模块在当前的市场上具有较高的生产和商业规模。钙钛矿的共同特征是三碘化CH3NH3PbI3。这是一个高电荷载体,具有更好的迁移率,因为高迁移率,光产生的电子能够产生更多的能量。光产生的电子可以移动到更远的距离,从而产生更多的能量。研究表明,与普通pv相比,100 mm左右的扩散长度(Hodes, 2013)在电子和锄头方面更高、更好,这使其具有更好的能量值生产(Hodes, 2013)。

钙钛矿被视为一个具有商业和功能吸引力的企业。钙钛矿的性质和物质属性引起了一些关注。钙钛矿是俄罗斯地理学会列夫·钙钛矿发现后的一个矿物名称。矿物结构由钙、钛和氧组成,形成CaTiO3。在对钙钛矿晶格排列的理解中,我们可以说钙钛矿是一种更大的带正电荷的分子阳离子,它存在于立方体中心。同一立方体的角上有正离子,立方体表面有带负电荷的阴离子。

现在考虑到钙钛矿的这种背景,以及它为市场提供的效率保证,它应该被认为是一种更商业化和更节能的产品,用于开发进一步的太阳能电池技术。然而,事实并非如此。在当代的研究分析中,经常有人指出钙钛矿可能存在的问题可能导致大规模的技术发展障碍。被引用的主要问题是钙钛矿细胞的稳定性(Snaith et al, 2014)。钙钛矿细胞可能不稳定,这可能影响其薄膜层的长期使用。此外,HTM的形式也存在一些问题。由于沉积真空过程的复杂性,薄膜层均匀性的发展也对稳定因素提出了挑战。这也将在本文中讨论。

除上述因素外,钙钛矿细胞的腐蚀形式也存在一些问题,腐蚀和腐蚀钙钛矿细胞。热稳定性也是一个问题。只要钙钛矿结构电池的稳定性问题能够得到解决,那么大规模生产是可能的。

The Perovskite solar cell is structured by means of a hybrid organic compound that is also of a light active layer. The Perovskite materials are usually cheaper to produce and are made of lead halides that are of easy production. Research indicates that these elements would increase solar efficiency by more than 3.8 percent and up to 21 percent and in addition to these advantages the Perovskite is seen to be a more commercially attractive venture. Startup companies are invested in Perovskite and the solar cell modules are available in a high productive and commercial scale in the market in current times. The common of the Perovskite is that of the triiodide CH3NH3PbI3. This is a high charge carrier with a better mobility rate and because the high mobility the light generated electrons would be able to generate for more energy. The light generated electrons would be able to move for a farther distance and can hence generate more energy as heat. Research shows that diffusion lengths are higher and better with about a 100 mm in terms of electrons and hoes that gives it a better energy value production compared to that of normal PVs (Hodes, 2013).

Perovskite is seeing to be a commercially and functionally attractive venture. It is the nature and the material attributes of the Perovskite that is seen to result in some concerns. Perovskite is a mineral name after the found of Russian Geographical Society, lev Perovski. The mineral structure is made of calcium, titanium and oxygen and has form CaTiO3. In the lattice arrangement understanding of the Perovskite it can be said that Perovskite is more of a larger positively charged molecular cation that is seen to be present in the cube centre. There are cations present in the corners of the same cube and there are negatively charged anions presented as atoms in the cube faces.

Now given this background on Perovskite, and the efficiencies that it guarantees for the market, it should be considered such that it is a more commercially and energy wise efficient product for developing further solar cell technologies. However, this is not the case. In contemporary research analysis it has often been pointed out that there might be issues with Perovskite that might result in large scale technology development impediments. Mainly the issue that is being cited is that of the stability of the Perovskite cell (Snaith et al, 2014). Perovskite cell may not be stable and this could affect long term use of its thin film layers. In addition, there are also issues in the form of HTM. Stability factors are also challenged because of the intricate process of depositing vacuum for development of the thin film layer uniformity. This will also be addressed in the article.

Added to the above factors there are issues in the form of corrosion of Perovskite cells that erodes and corrodes them. Thermal stability is also an issue. As long as the issues of stability can be addressed for the Perovskite structure cells then mass production is a possibility.
