“Innovation distinguishes between a leader and a follower.” – Steve Jobs

Elon Musk, with his disruptive technology mindset, has never been one to follow the beaten path. Instead, he has consistently redefined industries and, in the process, our very understanding of what is possible. Today, when we speak of Tesla, it is not merely about a company, but a revolution that has accelerated the world’s transition to sustainable energy. Today’s focus is the solar sector, an area rapidly expanding, and one where Tesla has made a game-changing discovery.

The Past and The Present

Traditionally, crystalline silicon has dominated the solar market, accounting for about 90% of all solar panels worldwide. But Tesla has always been about breaking the mold. Recently, they introduced an unprecedented solar power cell that is promising to redefine the future of solar energy.

Ferroelectric Crystals: The Future?

Tesla’s groundbreaking development revolves around ferroelectric crystals, a material that’s not only cheaper but also thinner than traditional solar cells. Unlike traditional solar cells which require the expensive and energy-intensive process of creating 99.99% pure polysilicon, these cells employ materials like barium titanate. This eliminates the need for highly skilled labor or sophisticated equipment for production, drastically cutting costs.

But how do they perform? Researchers found that by alternating thin layers of materials like barium titanate, strontium titanate, and calcium titanate, they could amplify the energy output by an astonishing factor of one thousand. Essentially, Tesla’s new cell can potentially supply a power output that could rival entire solar farms!

Challenges and Solutions

Like all innovations, the ferroelectric cells have their challenges. A notable issue is the reduced lifespan of thin coatings caused by high temperatures. However, Tesla is already a step ahead, researching thin films resistant to high temperatures.

Beyond Silicon

The advancements in solar technology are not limited to just Tesla. Recently, Bouge RV introduced a flexible thin-film solar panel made using copper indium gallium selenite (CIGS). These panels have been found to perform remarkably well in low sunlight conditions, possibly delivering three times as much electricity as a typical solar panel.

Tesla Powerwall: Storing the Future

While generating solar energy is one side of the coin, storing it is the other. This is where Tesla’s Powerwall comes into play. Essentially a gargantuan battery, the Powerwall ensures that excess energy produced during the day doesn’t go to waste, storing it for use during non-productive hours. Given the rising adoption of solar energy and the desire for home autonomy, the Powerwall is an essential companion to any modern solar system.


The pace at which solar technology is advancing is truly remarkable. With the discovery and development of new materials and methods, the future looks brighter than ever.
