The optical performances of the as-prepared CQD were acquired through UV-Vis and PL tests, showing that the CQD were suitable as sensitizers for DSSC. Thereby CQDbased DSSC with Pt counter electrode (CE) were experimentally fabricated, yielding the power conversion efficiency (PCE) of 0.21% and 0.28% respectively under AM 1.5 one sun illumination. Meanwhile, the CP were coated on FTO as CE for DSSC, and the favorable electrochemical properties of the CP-based CE were measured by EIS and Tafel. Therefore the CP-based DSSC with N719 sensitizer were constructed, and achieved the PCE of 1.45% and 1.40% respectively. The above results distinctly present the photovoltaic applications of CQD and CP concurrently derived from green vegetables as sensitizer and counter electrode for DSSC, which indicate the prospect for the realization of high-performance photovoltaic cells from low cost and environmentally friendly natural products","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133535605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical transmittance of SU-8 was tested. According to Urbach optical-absorption theory and Gaussian laser lateral spatial intensity envelope, relationship between theory and actual polymerization size of SU-8 was shown. Experimentally, we investigated multi-photon polymerization threshold and laser-induced damage of SU-8 under femtosecond laser irradiation with the pulse width of 45 fs at 800 nm by 1-on-1 tests. The polymerization and damage threshold at 45 fs are 2.7 and 8.9 TW/cm2, respectively. Polymerization and damage morphologies are shown with high contrast and polymerization sizes are measured under SEM. Theoretical polymerization sizes versus laser fluence are calculated by laser-induce multi-photon polymerization size analysis (LMPSA), including Urbach optical-absorption theory and Gaussian laser lateral spatial intensity distribution. The calculated results show that diffusion exists in the femtosecond laser-induced polymerization.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133425848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laser induced damage was attributed to the increase of the free electron density and temperature enhancement during the irradiation of high repetition rate picosecond laser. The correlation of laser induced damage threshold with pulse numbers was researched. At higher repetition rate, the laser induced damage threshold was reduced more with the increasing of pulsed number. We found that the defects absorption played an important role to the laser induced damage properties of dielectric reflective optical coatings. The damage morphology showed that the evolution of damage site was significantly influenced by the accumulation of laser energy. In order to enhance the resistance capacity, the dielectric reflective optical coatings were annealed with temperature of 260°C. The defect absorption was reduced after the annealing process. For the annealed coating, the laser induced damage threshold under high repetition rate picosecond laser was enhanced as a result of the suppression of defects in the coating.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115940184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
