How Capsaicin in Chilli Pepper Spices up Solar Pannels

Capsaicin



Capsaicin is the name of the compound responsible for the hotness of chili pepper.

Researchers have found that solar panels treated with Capsaicin is more efficient than others.

How efficient are solar panels?

The efficiency of present day cells and panels are relatively low.

`Solar panel efficiency is generally between 15 to 20 percent.

Solar cell efficiency can however reach up to 42% in some cases.

It is worthy of note that, most solar cell performances are measured under laboratory conditions.

SOLAR PANEL TYPE EFFICIENCY
Monocrystalline Solar Panels The current delivered monocrystalline solar panel efficiency stands at 22-27%
Polycrystalline Solar Panels The current delivered polycrystalline solar panel efficiency stands at 15-22%
Thin Film Solar Panels thin film cells deliver between 15-22% solar panel efficiency

Qinye Bao at East China Normal University in Shanghai and his colleagues added capsaicin to these ultra-thin perovskite solar cells during the manufacturing process.

Bao and his team suspected that capsaicin might have an energy-boosting effect because it can free up electrons that can go on to carry a charge.

They tested the capsaicin-treated solar cells in the laboratory by exposing them to artificial light to simulate sunlight and measuring the electrical current running through them.

What was the result of this experiment?

The solar Panels treated with Capsaicin became even more efficient, yielding 21.88 as against the non-treated ones with 19.1 percent.

The team then analysed the solar cells with spectroscopy while conducting energy and found that the addition of capsaicin did indeed lead to a greater number of free electrons available to conduct current at the solar cells’ surface.

The exact mechanism behind this improvement is still being debated. Bao and his colleagues hypothesise that capsaicin molecules react with the lead ions in the solar cell to free up more electrons to conduct current.

while speaking Qinye Bao said:

It is our priority to select sustainable forest-based biomaterials

Capsaicin is a w-cost, natural, sustainable, and Earth-abundant.

Many natural or Biochemical compounds are currently being tested to see if they can improve the efficiency of solar cells.

Polymer and Molecular Semiconductors are now also being used to increase solar efficiency.

As over 600,000 African women and children die anually due to the use of inefficient energy sources.

an improvement in the already existing renewable energy sources will save thousands of lives and improve millions of lives in under-developed countries.
