New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation
Due to the recent improvements in the efficiency with which solar cells made from organic (carbon-based) semiconductors can convert sunlight into electricity, improving the long-term stability of these photovoltaic devices is becoming an increasingly important topic.
Cooling Down Solar Cells, Naturally
Too much sun and too much heat can reduce the efficiency of photovoltaics. A solar farm with optimally spaced panels facing the correct direction could cool itself through convection using the surrounding wind. Researchers explored how to exploit the geometry of solar farms to enhance natural cooling mechanisms.
Casting Shadows on Solar Cells Connected in Series
Even small objects, such as dust and leaves, can block sunlight from reaching solar cells, and understanding how the loss of incoming radiation affects power output is essential for optimizing photovoltaic technology. In the Journal of Renewable and Sustainable Energy, researchers explore how different shade conditions impact performance of single solar cells and two-cell systems connected in series and parallel. They found that the decrease in output current of a single cell or two cells connected in parallel was nearly identical to the ratio of shade to sunlight. However, for two cells running in series, there was excess power loss.
Measuring Photovoltaic Performance Indoors
As photovoltaic technology continues to progress, PV devices’ applications in harvesting energy from indoor ambient light have become more realistic. Some combinations of PV material and light source can be more efficient in converting power than the same material under solar illumination, and a better understanding of these relationships is needed to fully characterize the behavior of solar cells under very low illumination conditions.
