Manufacturing 100-µm-thick silicon solar cells with efficiencies greater than 20% in a pilot production line

Abstract: Present address: Arizona State University, School of Electrical, Computer and Energy Engineering, 551 E. Tyler Mall, Tempe, AZ 85287, USA.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 integr… Show more

“…68,69 The thickness of the cut wafers is typically 180 mm, with a trend towards thinner wafers during the last 15 years. 5,[70][71][72][73] The kerf loss is typically on the order of 100 mm, representing an important cost factor. Silicon solar cell manufacturing typically starts with chemical etching and surface texturing of the wafers.…”

“…5 Recently, research has focused on thin-film crystalline silicon solar cells to decrease the Si cost per peak watt. [6][7][8] Thin-film crystalline silicon solar cells not only reduce the amount of silicon used, but also promise low-cost processing and lightweight mechanical flexibility for modules. With effective anti-reflection and light trapping, 10% and 13.7% power conversion efficiency results have been achieved on the ∼2 μm and ∼10 μm thick crystalline silicon solar cell respectively.…”
