The traditional dye absorption material were replaced by the fourth generation light harvesting material, the CH3NH3PbI3 which deemed to reach the PV efficiency limit. The complete conversion of PbI2 into CH3NH3PbI3 crystal structure vital in lowering the internal series resistance. With this new light harvesting material were used able to achieve 7.75 efficiency via sequential two step deposition of perovskite. © 2017 IEEE. publisher: Institute of Electrical and Electronics Engineers Inc. date: 2017 type: Conference or Workshop Item type: PeerReviewed identifier: Saheed, M.S.M. and Mohamed, N.M. and Singh, B.S.M. and Perumal, V. and Saheed, M.S.M.
