New Kind of "Tandem" Solar Cell Developed

March 28, 2015 by Energy @ MIT

Solar Cell Invention

Researchers have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations.[read more]

Improving a New Breed of Solar Cells

May 29, 2014 by Energy @ MIT

New Solar Cells

Solar-cell tech has advanced rapidly, as hundreds of groups around the world pursue more than two dozen approaches using different materials, technologies, and approaches to improve efficiency and reduce costs. Now a team at MIT has set a new record for the most efficient quantum-dot cells.[read more]

Getting More Electricity out of Solar Cells

Solar Cell Efficiency

When sunlight shines on today’s solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons — behavior that could significantly increase solar-cell efficiency.[read more]
