Developments in solar technology have focused on advancing high-efficiency N-type tunnel oxide passivated contact (TOPCon) architectures. 

In September 2026, Indosol Solar and the Australian National University (ANU) entered a collaboration to bridge the gap between laboratory research and commercial manufacturing. This partnership aims to increase solar cell conversion efficiency and improve resistance to light and ultraviolet-induced degradation using Indosol Solar’s manufacturing facilities in India.

By October 2026, industry activity showed a continued emphasis on TOPCon technology, with Suntech highlighting modules achieving cell efficiencies of up to 27.5%. The sector is also expanding its scope to include next-generation photovoltaics and space solar applications, as noted in upcoming industry conferences.
