To upscale DSC size to commercial size, our group was involved in developing a commercial DSC panel, which could show the industrial way and prospect. The repeatable DSC module with the size of 150mm×200mm and photoelectric conversion efficiency around 6% was reproduced in our laboratory. The DSC panel up to the size of 450mm×800mm was fabricated. This is the high efficiency and industrial production design of a DSC panel, a primary power station with 500W was installed on our roof for charging the battery. The study on the stability and performance of the DSC module, panel and future production are ongoing in our laboratory. In this article, we will report a systematic study in the test and the design from the single cell, the modules, to the panels, and our design of a 500W primary DSC power station.
