Toshiba developed polymer film-based Perovskite photovoltaic module with PCE of 15.1%

Toshiba, the world-leader in development of perovskite photovoltaic modules for next-generation solar power generation, announced to develop a new coating method for the perovskite layer that boosts power conversion efficiency (PCE) to 15.1% for 703cm2 module, the highest for any large, polymer film-based perovskite photovoltaic module. The innovative coating method for perovskite layer also greatly reduces production time and costs, contributing to a lower cost for solar power generation.

The company previously developed a two-step coating process that first applied a layer of PbI2 (lead iodide) ink to a substrate, followed by a layer of MAI (methyammonium iodide, CH3NH3I) ink, triggering a reaction that formed an MAPbI3 layer. However, this multi-step approach had a low coating rate and often left unreacted sections in the perovskite layer. The alternative is a one-step process that applies MAPbI3 ink directly, but it is not easy to control crystallization of the MAPbI3 and obtain a uniform perovskite layer across a large area. A new coating method that solves these problems was required.

The company has developed a one-step meniscus coating method that uses improved ink, film drying processes and production equipment to form a uniform perovskite layer over an area as large as 703cm2. These innovations halve the steps for deposition of the perovskite layer, and raise the coating speed to 6 meters per minute on a 5×5 cm2 module, a rate that meets requirements for mass production.

The company previously reported 703cm2 polymer film-based perovskite photovoltaic modules, the one-step meniscus coating method achieves a PCE of 15.1%, the world's highest ever for a polymer film-based large-area perovskite photovoltaic module. This higher PCE and the faster, simplified production process, significantly advance progress toward the commercialization of highly efficient, low-cost, polymer film-based perovskite photovoltaic modules.
