Intel and IBM have joined the team of technology companies making alternative-energy projects, announcing separate efforts to produce their own solar cells.
Intel said it has spun off a new company called SpectraWatt to make photovoltaic cells for solar modules. The company will be based in Oregon, US and will make 60 megawatts worth of solar cells a year.
IBM said it would work with a Japanese semiconductor and flat-panel manufacturer, Tokyo Ohka Kogyo, to make cheaper solar cells.
