Perovskite solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials.As a new generation of photovoltaic technology,perovskite solar cells have the following advantages over traditional crystalline silicon: less raw material usage,only 1/1000 of crystalline silicon,and low material purity requirements;high photoelectric conversion efficiency,up to more than 30%,exceeding the conversion limit of crystalline silicon,and the efficiency of perovskite and crystalline silicon stacking can reach more than 33%;low temperature coefficient, good weak light power generation, the actual single watt power generation is 5-10% higher than that of crystalline silicon modules;low cost, more than 40% lower than that of crystalline silicon modules.
Technical advantages:
We have developed a unique “solid phase crystallization method”technology that can be applied to substrates with different roughness to ensure the uniformity of the film layer.It can not only overcome the influence of large-area conductive glass thickness deviation on film thickness uniformity,but also be applied to the velvet substrate of crystalline silicon cells.
The developed device can be applied to different application scenarios.It can be used as a single-cell battery in the centralized or distributed photovoltaic power generation market,or as a top cell of crystalline silicon to form an upgraded product of crystalline silicon photovoltaic.
Product application:
Single-junction high-efficiency perovskite solar module can be used in centralized or distributed photovoltaic power stations;
Semi-transparent perovskite solar module can be used in building photovoltaic curtain walls;
Perovskite-crystalline silicon stacked cells are upgraded products in the existing crystalline silicon photovoltaic market.
