Ka Semicera'sInP le CdTe Substrate, o ka lebella boleng bo holimo le boqapi bo nepahetseng ho fihlela litlhoko tse ikhethileng tsa lits'ebetso tsa hau tsa tlhahiso. Ebang ke bakeng sa lisebelisoa tsa photovoltaic kapa lisebelisoa tsa semiconductor, li-substrates tsa rona li etselitsoe ho netefatsa ts'ebetso e nepahetseng, ho tšoarella, le ho tsitsisa. Joaloka morekisi ea tšepahalang, Semicera e ikemiselitse ho fana ka litharollo tsa boleng bo holimo, tse ka tloahelehang tse tsamaisang boqapi makaleng a elektronike le matla a ka nchafatsoang.
