실리콘 태양전지는 현재 태양광 시장의 90% 이상을 차지하고 있으며 향후에도 기술 개발을 통해 태양광 시장을 주도하는 기술로 예상되고 있다. 실리콘 태양전지의 가격 경쟁력 확보를 위해 새로운 기술이 개발되고 있는 상황에서 효율 한계를 극복하기 위한 탠덤 태양전지 연구가 주목 받고 있다. 실리콘 기반 탠덤 태양전지의 여러 후보 물질 중 페로브스카이트는 공정의 용이성뿐 아니라 물질의 특성이 탠덤 태양전지 소재로써 적합하여 최근 주요하게 연구되고 있다. 본 논문 에서는 페로브스카이트 실리콘 탠덤 태양전지의 연구 동향에 대해 살펴보고자 한다.

In this study, a customized semi-passive RFID receiver module was implemented for in-VIVO deep tissue photo-therapy. A novel wireless technique is required due to a limitation of RF communication in body environment, as internal body has a complex structure such as, skin, fat, skeleton, water, and so on. Recently, coherently incoherent beamforming (CIB) based on RFID was introduced and it is able to transmit wireless signal with high reliability under the incoherent condition such as in-VIVO deep tissue. The proposed miniature photo capsule based on RFID consists of miniature controller, ultra small LED array and wireless RFID chip. RF Reader can access with standard RFID protocol (ISO 18000-6c) using UHF RFID antenna, a control command is wirelessly writtern on USER Bank memory. With received control command, therapy LED array dims with mulilevel under timer control. The signal process of designed RFID photo therapy capsule is analyzed and evaluated under the various environments in detailed.
