Solar panels cells boosted by chilli peppers’ chemical

The treatment of solar cells with capsaicin, a chemical used to make chilli peppers hot, has been found to be efficient at changing solar power. It is essential to note that ultra-thin solar cells, which are made with lead materials, have the ability to absorb light in a more efficient manner compared to silicon-based solar cells. However, these cells do not convert energy more efficiently since they lose some energy to heat.  Qinye Bao has revealed this at the East China Normal University situated in Shanghai together with his colleagues. Bao together with his team were able to add capsaicin to the ultra-thin perovskite solar cells while they were carrying out a manufacturing process. They suspected that capsaicin contains an energy-boosting effect since it is capable of freeing up electrons that carry a charge.

The team was carrying out an experiment in the laboratory where they exposed the capsaicin-treated solar cells to artificial light and measured the electrical current that was running via them. As a result, the solar cells were made more efficient by the capsaicin leading to energy conversion of 21.88% compared to 19.1% power without capsaicin. After analyzing the solar cells which have spectroscopy while it is conducting power, the team found out adding capsaicin freed a greater number of electrons to run current at the surface of solar cells. Consequently, there was less energy leakage through heat.

The debate behind this improvement mechanism is still going on. Bao and his team said that capsaicin molecules have the ability to react with solar cells’ lead ions that help to free up additional electrons to run current. Bao noted that one of their main priorities is selecting long-lasting forest-based biomaterials.  He added that capsaicin is natural, cheaper, Earth-abundant, and sustainable. Tsutomu Miyasaka said that different research organizations and universities are carrying out tests on the majority of natural organic compounds to find out that if they contain the same impact as capsaicin. Perovskite solar cells were invented by the University of Yokohama, situated in Japan in 2009 and help to boost solar cells’ stability and efficiency at lower costs.

Solar cell analysis, which lies somewhere in between physics and chemistry, is just a subject of materials science. It requires a lot of labor to create new solar cell technology or procedures. The usual solution is to spend a lot of time checking the efficiency of a vast range of comparable but significantly altered cell designs. The solar cells consist of the stacked layers of various materials, as well as by modifying one part; it is difficult to determine what will occur to the overall structure’s output.
