Perovskite solar cells use organic-inorganic hybrid metal halides with perovskite crystal structure as the absorbing layer. Perovskite materials have better light absorption and adjustable band gaps, which have two core advantages compared to crystalline silicon batteries: higher theoretical conversion efficiency and lower production costs& Nbsp;

ΠEfficiency enhancement:;

At the theoretical limit, the maximum conversion efficiency of crystalline silicon solar cells, PERC monocrystalline silicon cells, HJT cells, and TOPCon cells is 29.40%, 24.50%, 27.50%, and 28.70%. The theoretical maximum conversion efficiency of single junction perovskite batteries is 31%, and the theoretical efficiency of multi junction batteries is 45%& Nbsp;

Cost reduction:;

1) In terms of preparation costs, the continuous increase in silicon material prices has led to a certain degree of decline in profits for downstream battery and component manufacturers under pressure. The production process of PSCs does not require silicon materials, and the raw materials required for producing metal halide perovskites are abundant and inexpensive. Moreover, the preparation of precursor liquids does not involve any complex processes& Nbsp;

2) In terms of equipment investment, the investment amount required for perovskite to achieve a 1GW production capacity is about 500 million yuan, which is about half of that of crystalline silicon. Compared to the higher investment of second-generation GaAs thin film solar cells, the cost is only 1/10& Nbsp;

Example model:

Mainly used for P1/P2/P3 etching, P4 edge cleaning, BIPV transparency, and insulation etching of thin film solar cells, suitable for thin film cells such as perovskite, CIGS, CdTe, and color changing glass. Perovskite related laser processing equipment has been shipped in bulk to multiple leading enterprises and universities in China, with a market share of over 60%& Nbsp;
