• Technology Introduction

For large scale solar cells, the high light absorbance and cost-effective material, perovskite MAPbI3, was introduced as light-harvesting layers. Once combined with the technologies of laser etching , screen printing and 3D dispensing, we are able to develop a commercilizable procedure for making large scale module with active area 15.12 cm2. This module shows excellent PV performance with Voc 7 V and PCE 11 % under indoor light irradiation.
 

•  Scientific Innovation

All the fabrication procedures for preparing of the carbon electrode based perovskite solar cell modules are under the ambient atmosphere conditions. The non-encapsulated modules showed 11% PCE under indoor light illumination and still maintained great enduring stability with PCE over 90% when the device was stored at 20℃ and 50% RH for near 2000 hours.
