5GSOLAR: On track for effective project commercialisation

Maciej Sibiński, Research Professor from Tallinn University of Technology, highlights the 5GSOLAR project, which is on track to commercialise solar cells. The development of the new Sb2(S,Se)3, (Sb,Bi)2Se3 solar cells is currently underway, but effective commercialisation is crucial for successful growth, and proper perspective and potential technology applications are vital for future advancement. Intense effort was recently put into the development of Sb2S3 and Sb2Se3 structures in the Tallinn University of Technology’s Laboratory for Thin Film Energy Materials group, bringing about significant progress in both technology and efficiency levels. By using low-temperature and low-energy-consumption closed-spaced sublimation and chemical spray pyrolysis methods, the manufacturing technology was elaborated to achieve an industrial level.
