Next generation crystalline silicon solar modules will be more efficient with better temperature performance.
BURNABY, BC: Day4 Energy Inc. is combining its solar photovoltaic technology with German firm Roth & Rau AG’s production technologies to develop what the two companies are calling “the next generation” of crystalline silicon solar modules.
The companies have announced a three-way memorandum of understanding that also includes Alinement BV, a prospective Day4 solarSYSTEMS partner in the Netherlands that would produce the modules in 2012 with an initial capacity for 80 megawatts.
Roth & Rau’s PV cell and hetero-junction turnkey manufacturing line will be combined with Day4’s advanced PV cell, module and production technologies to produce modules with increased cell efficiency and temperature performance.
The companies said the aim of the collaboration is to reduce costs and achieve the highest possible efficiency by minimizing production steps by integrating wafer, cell and module production.
Roth & Rau www.roth-rau.de said its hetero-junction solar cells offer an efficiency potential of more than 20% while delivering “favourable manufacturing costs. It said that adding Day 4’s contacting technology will further enhance module efficiency.
“The Day4 cell interconnection technology secures PV cell high efficiency at the module level and minimizes cell-to-module energy losses,” said Leonid Rubin, Day4 Energy’s vice-president and chief technology officer. “In addition, Day4’s low temperature module production technology provides a unique opportunity to manufacture PV modules with temperature sensitive PV cells.”
The companies plan to have 500 megawatts of manufacturing capacity in a single Netherlands location.
