Application scenarios of flexible perovskite solar cells: consumer electronics and home DIY, outdoor equipment attachment, public service and outdoor facility attachment, agricultural greenhouse/sunroom film, passenger car and freight truck photovoltaic film (CAPV/VAPV), photovoltaic building attachment (BAPV), etc.

Flexible perovskite solar cells (f-PSCs) have achieved efficiencies of up to 25.1% in 12 years, and improvements in the last three years have increased the efficiency from 21.7% to 25.1%. Challenges include chemical and physical deformation of polymer substrates under different environmental conditions. Solving these challenges is critical to narrowing the efficiency gap with rigid substrates. Large areas of perovskite solar cells involve tandem cells (P1, P2, P3) to mitigate the effects of resistivity on performance.

Laser etching optimization becomes critical and is challenging on flexible substrates due to chemical and physical interactions with deposited layers. The thermal effects of the laser etching process are particularly evident in flexible devices, as polymer substrates such as PET and PEN have lower thermal resistance than rigid substrates. Excessive local heating during laser etching can cause substrate deformation, layer delamination, and changes in material properties, such as reduced conductivity or reduced mechanical integrity. Microchip's customized complete optical solution ensures precise control of laser parameters, including pulse duration and energy density, to minimize thermal damage and ensure the structural and functional integrity of flexible devices.
