How Does a Solar Cell Work?

The electronics of the solar cell is presented including the PN junction diode. The electrical model of the solar cell is presented along with the solar cell voltage versus current performance. A SPICE simulation is done on an electrical model of the solar cell.

New high-efficiency perovskite solar cells

Stanford and Oxford scientists have created novel solar cells from crystalline perovskite that could rival and even outperform existing silicon cells on the market today. The new design converts sunlight to electricity at efficiencies of 20 percent, similar to current technology but at much lower cost.

In the video, Professor Michael McGehee and postdoctoral scholar Tomas Leijtens of Stanford describe the discovery, which could lead to thin-film solar cells with a record-setting 30% efficiency.

The research was funded in part by Stanford’s Global Climate and Energy Project (http://gcep.stanford.edu).
