Solar mini-module with perovskite solar cells
Project Director: Dr. Leonat Lucia
Over the past decade, a new generation of solar cells arise remarkably, the hybrid perovskite solar cells (HPSCs, or simply PSCs). They cumulate exceptional intrinsic photophysical properties with manufacturing versatility and low-cost precursors materials, therefore presenting a huge potential for large-area production on an industrial scale.
This project, brings previous research conducted by our group, in the field of perovskite solar cells, closer to commercial applications by fabricating large-area perovskite solar cells and integrating them into functional solar modules. The Solar-PVK project aims to develop efficient, large-area PSCs, with an active area exceeding 1 square cm, using low-cost solution deposition technologies. These devices will be connected together and encapsulated in a sealing box fabricated in-house, to assemble a prototype of a functional solar module. This solar module will be integrated into a solar portable charger, able to power for example a mobile phone, capable of supplying enough energy, in case of emergency situations or off-grid low power applications.

At stage II of the project, a slot-die/ dr. blade thin film deposition system was assembled (in-house), installed, and tested. With it we fabricated thin films of perovskite and h-type layers for solar cells with a large active area, of over 2.4 square cm, with a power conversion efficiency of 4%.
Especially for these types of cells, upper electrode deposition masks and a cell contacting device for measurement were manufactured.
Laboratory experiments to improve efficiency are ongoing.
