Perovskite solar cells are the fastest growing solar technology in history, with demonstrated power conversion efficiencies exceeding 23%, above established solar technologies such as polycrystalline silicon, CIGS or CdTe. The main advantage of perovskites is their ease of processing, i.e. they can be printed from simple inks, and their elements are in abundance; ensuring their long-term low cost. This results in very high-quality materials that can also be applied in lighting applications such as general room lighting, displays for hand-held devices and larger screens and communication devices. It is highly unusual that low-cost materials that can efficiently convert light to electricity can also efficiently do the reverse process of electricity to light. Manufacturing these kinds of materials does not require the expensive high-tech infrastructure currently needed to make electronic components. This makes this family of materials extremely attractive for many important technological sectors beyond solar energy.The main aim of our project is to improve the performance and stability of perovskite solar cells by introducing a novel layered perovskite material to extract charge from the device. This approach removes the requirement to employ very expensive organic layers currently in use and will lead to significant further cost-savings, making the technology more attractive for commercial enterprises. To achieve this, our project aims to introduce moisture barrier layers that can efficiently allow electrical current flow only in one direction through them based on perovskite ``quantum-well'' structures, i.e. very thin sheets of the perovskite material (several atom layers in thickness) that are sandwiched between equally thin plastic sheets. By carefully selecting the appropriate plastic sheet material, the structure becomes more resistive to water, and thus more stable, while maintaining the high-quality electronic properties of the perovskite family.By developing these novel structures, our project will enable the manufacture of new types of electronic devices beyond solar cells. For instance, materials that show quantum-well properties are very useful for the fabrication of lasers. These are integral to information technologies and are also used in many other applications that could be even more widespread if they were sufficiently cheap.

Percent太阳能电池是历史上发展最快的太阳能技术，已证实的功率转换效率超过23%，高于多晶硅，CIGS或CdTe等现有太阳能技术。钙钛矿的主要优点是易于加工，即它们可以用简单的油墨印刷，并且它们的元素丰富;确保其长期的低成本。这导致非常高质量的材料，也可以应用于照明应用，如一般的室内照明，手持设备和更大的屏幕和通信设备的显示器。这是非常不寻常的，低成本的材料，可以有效地将光转化为电，也可以有效地做电到光的逆过程。制造这些材料不需要目前制造电子元件所需的昂贵的高科技基础设施。这使得这一系列材料对太阳能以外的许多重要技术领域极具吸引力。我们项目的主要目的是通过引入新型层状钙钛矿材料来从设备中提取电荷，从而提高钙钛矿太阳能电池的性能和稳定性。这种方法消除了使用目前使用的非常昂贵的有机层的要求，并将导致进一步显著节省成本，使该技术对商业企业更具吸引力。为了实现这一目标，我们的项目旨在引入防潮层，该防潮层可以基于钙钛矿“量子阱”结构有效地允许电流仅在一个方向上通过它们，即非常薄的钙钛矿材料片（厚度为几个原子层）夹在同样薄的塑料片之间。通过仔细选择合适的塑料片材料，该结构变得更防水，因此更稳定，同时保持钙钛矿家族的高质量电子特性。通过开发这些新结构，我们的项目将能够制造太阳能电池以外的新型电子器件。例如，具有量子阱性质的材料对于激光器的制造非常有用。这些是信息技术的组成部分，也用于许多其他应用，如果足够便宜，这些应用可能会更加广泛。
