Perovskite Solar Cell
Chemistry
Patented thin-film solar cells based on perovskite materials with high efficiency and low production cost.
The patented thin-film solar cells utilize perovskite materials, which have emerged as a promising alternative to traditional silicon-based solar cells due to their high power conversion efficiency and potential for low production costs. Perovskite solar cells (PSCs) have achieved efficiencies over 23%, rivaling traditional silicon-based solar cells, but with the advantage of being potentially cheaper to produce. The perovskite material serves as the light-absorbing layer, allowing for the efficient conversion of sunlight into electrical energy. The thin-film design enables the use of a minimal amount of perovskite material, further reducing production costs. This design consists of a transparent conductive oxide (TCO) layer, an electron transport layer (ETL), the perovskite layer, a hole transport layer (HTL), and a back electrode. The TCO layer, typically made of fluorine-doped tin oxide (FTO) or indium-doped tin oxide (ITO), facilitates the collection of charge carriers. The ETL and HTL are crucial for efficient charge transport and preventing recombination losses. The perovskite layer, with its exceptional light-absorbing properties, is the heart of the solar cell. Its bandgap can be tuned for optimal energy conversion by adjusting the composition of the perovskite material. The patented technology likely involves specific innovations in the deposition methods of these layers, material composition, and interface engineering to achieve high efficiency and stability. The low production cost is achieved through the use of inexpensive materials and scalable deposition techniques, such as slot-die coating, blade coating, or roll-to-roll printing. These methods enable the rapid and cost-effective deposition of perovskite and other layers over large areas, making the technology suitable for commercial applications. The combination of high efficiency and low production costs makes these patented perovskite-based thin-film solar cells highly competitive in the renewable energy market.
