Ultra-high efficiency solar power generation

Are double-junction solar cells a new era of ultra-high-efficiency photovoltaics?

Sophie X. An The recent tremendous progress in monolithic perovskite-based double-junction solar cells is just the start of a new era of ultra-high-efficiency multi-junction photovoltaics. We report on triple-junction perovskite–perovskite–silicon solar cells with a record power conversion efficiency of 24.4%.

What is the power conversion efficiency of triple-junction solar cells?

We report on triple-junction perovskite–perovskite–silicon solar cells with a record power conversion efficiency of 24.4%. Optimizing the light management of each perovskite sub-cell (∼1.84 and ∼1.52 eV for top and middle cells, respectively), we maximize the current generation up to 11.6 mA cm −2.

Are solar panels becoming a major player in electricity generation?

The sight of solar panels installed on rooftops and large energy farms has become commonplace in many regions around the world. Even in grey and rainy UK, solar power is becoming a major player in electricity generation. This surge in solar is fuelled by two key developments.

Is solar energy a good investment?

While the installation cost is easy to obtain, the revenues from generating solar electricity at home are a bit more nuanced. You can save money by using less energy from the grid, especially in periods when it is costly, and you can also sell some of your surplus electricity back to the grid.
