Perovskite promises power-producing paint for pennies per pint

Back in 2009, a research team from the University of Tokyo led by Professor Tsutomu Miyasaka found that a substance called perovskite had the potential to generate solar power. However, at the time it only had a very weak power conversion efficiency (PCE) of about four percent and would break down in just a few minutes.

Because of these sizable flaws, not could practical use could be made of perovskite and the discovery lay dormant for a few years. Then, after a Korean team managed to double the PCE in 2011, research into the material was reignited. Now as scientists around the world continue to work on it, the PCE has become well above 20 percent and comparable with the standard silicon-based solar panels that we see today.

With perovskite being drastically cheaper to produce, more flexible to use, and now as efficient as regular solar panels, could we be on the verge of a solar energy revolution?

Sharp Corporation Potentially Not Doomed After All, Unveils Amazing New Solar Energy Panels

Not seven days ago, netizens were chuckling away at the expense of electronics giant Sharp Corporation’s efforts to install anti-bacterial air purifiers on top of photocopiers, with many forecasting the end for one of Japan’s once greatest innovators.

But recent news of affordable, ultra-efficient and easy-to-install solar panels from the very same company has brought those fervently blogging fingers to a sudden halt.

Solar panels, while very effective in the right environment and conditions, are hardly the most reliable of energy sources. Add to this the cost involved to purchase and install the panels, as well as their less-than-appealing aesthetic design, and it’s little wonder that few people take the idea seriously or are willing to invest the capital to get their home hooked up.

Sharp, it seems, has come up with solutions to the majority of these problems, and have a few extra surprises for us… Read More
