Researchers examine light-induced performance increase of carbon-based perovskite solar module

Scientists from Japan's Kishu Giken Kogyo and University of Hyogo, Switzerland's Solaronix and Germany's Fraunhofer ISE have examined the long-term stability of perovskite solar cells using layers of mesoporous carbon, building on previous work that showed the strong potential of this approach.

This recent work demonstrated a light-soaking effect, which allowed them to fabricate cells that retained 92% of their initial performance after 3,000 hours in damp heat conditions – which the researchers say is equivalent to 20 years in the field.

Researchers improve perovskite-based solar-cells' performance

Researchers at Aalto University have developed a method for improving perovskite-based solar cells, that builds on previous breakthroughs improving the efficiency and longevity of such cells using printing methods (carbon back contact based perovskite solar cells or CPSCs). These findings make it possible to further enhance the efficiency of these types of solar cells.

In the new method, the perovskite solar cells were exposed to 40-degrees in a chamber where humidity was kept in the level of 70% (±5%). This kind of environment normally degrades the properties of perovskite solar cells. In this case, the treatment led to surprising growth of the perovskite crystals, which naturally absorb sunlight and generate electricity. “The photovoltaic performance was significantly enhanced, and the overall efficiency increased almost 45%,” say the researchers.

Warwick U team designs tin-based perovskite solar cells

Researchers at the University of Warwick in the UK designed an environmentally friendly perovskite solar cell in which lead is substituted for tin with reportedly undiminished rates of performance but at cheaper cost and with lower toxicity.

The team stated that tin-based perovskites are much more stable than previously thought, and also render solar power cheaper, safer and possibly even more commercially attractive. "The device structure can be greatly simplified without compromising performance, which leads to the important advantage of reduced fabrication cost" the scientists say.
