The dosimetric characteristics of the developed system were evaluated including its energy dependence, dose linearity, and angular dependence. Calibration factors for the signal measured by the system and absorbed dose\u2010to\u2010water were obtained by setting reference conditions. The application and correction accuracy of the developed system were evaluated by comparing the absorbed dose\u2010to\u2010water measured using a patient treatment beam with that measured using the ion chamber.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The responses of STFSC\u2010SS to energy, field size, depth, and source\u2010to\u2010surface distance (SSD) were more dependent on measurement conditions than were the responses of the ion chamber, although the former dependence was due to the scintillator screen, not the solar cell. The signals of STFSC\u2010SS were also dependent on dose rate, while the responses of solar cell alone and scintillator screen were not dependent on dose rate. The scintillator screen reduced the output of solar cell at 6 and 15 MV by 0.60 and 0.55%, respectively. The different absorbed dose\u2010to\u2010water measured using STFSC\u2010SS for patient treatment beam differed by 0.4% compared to those measured using the ionization chamber. The uncertainties of the developed system for 6 and 15 MV photon beams were 1.8 and 1.7%, respectively, confirming the accuracy and applicability of this system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The thin\u2010film solar cell\u2010based detector developed in this study can accurately measure absorbed dose\u2010to\u2010water. The increased signal resulting from the use of the scintillator screen is advantageous for measuring low doses and stable signal output. In addition, this system is flexible, making it applicable to curved surfaces, such as a patient's body, and is cost\u2010effective.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mp.15664","type":"journal-article","created":{"date-parts":[[2022,4,9]],"date-time":"2022-04-09T08:49:41Z","timestamp":1649494181000},"page":"4768-4779","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Development
