Manufacturing 100-mm-thick silicon solar cells with efficiencies greater than…

Reducing wafer thickness while increasing power conversion efficiency is the most effective way to reduce cost per Watt of a silicon photovoltaic module. Within the European project 20 percent efficiency on less than 100-mm-thick, industrially feasible crystalline silicon solar cells (“20plms”), we study the whole process chain for thin wafers, from wafering to module integration and life-c…
