Low-cost solar absorber could supercharge solar power plants

One of the major challenges in developing solar panels has been creating photovoltaic cells which can absorb as much solar energy as possible – without overheating to the point that they begin to simply radiate energy back into the atmosphere. In the past, this has meant that commercially available solar cells only manage to convert about 30% of sunlight they absorb into energy. Researchers from Purdue University may have found a way to overcome this issue and modify regular silicon wafers to more...
