Future technology


Perovskite is named after Russian mineralogist Perovski, originally referring to the mineral calcium titanate (CaTiO3), and later called the structure ABX3 and similar crystals as perovskite minerals.


A: Organic ions, CH3NH3+, C2H5NH3+, etc.;

B: Divalent metal ions, Pb2+, Sn2+, etc.;

X: Halogen anion, Cl-, Br-, I-, etc.


Solar cell development history


The first generation: crystalline silicon solar cells

1950s Bell Labs reports

Monocrystalline silicon conversion efficiency 26.7%

Polysilicon conversion efficiency 20.8%

Approaching the limit, with a market share of 89%

Relying on high-purity silicon, manufacturing costs are high

Second generation: thin-film solar cells

Amorphous gallium arsenide efficiency 30%

Rare earth elements are required

Complex process CVD or PECVD

The preparation process is heavily polluted

It is difficult to promote further

The third generation: new solar cells such as perovskite

Since 2009, the highest PCE has reached 25.7%

Flexible PSCs up to 21.75% PCE

Low manufacturing cost

Flexible structures can be prepared

At the World Economic Forum 2016, it was named one of the "Top 10 Emerging Technologies with the Most Commercialization Potential"

01High photoelectric conversion efficiency

The flexible substrate of silver nanowires is used instead of ITO, which has a simple preparation process and high conversion efficiency.

02Low manufacturing cost

The preparation process of full coating is adopted to reduce costs.

03Flexible structure can be prepared

The flexible substrate is light and thin, bendable and foldable, easy to carry, and the scene is more extensive.

The traditional preparation process is complex, cumbersome in steps, consuming, and costly.
