It should also provide stable irradiance, low thermal influence on the sample, good reproducibility after shutter operation, and stable performance at low irradiance levels.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">SAN-EI has developed the XES-50S3-PSC as a solar simulator configuration designed for perovskite solar cell research.<\/p>\n\n\n\n<h2 id=\"anchor-01\"

dedicated solar simulator is useful for PSC research<\/h2>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">In PSC research, small-area cells and test samples are commonly used.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The measurement area is often smaller than that used for conventional solar cell evaluation.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Therefore, stable irradiance over a small effective area is especially important.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">In addition, perovskite materials can be sensitive to heat, light intensity, and measurement history. <\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Even small changes in irradiance or sample temperature may affect measurement results.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">For this reason, the stability of the light source and the thermal influence on the sample must be carefully considered.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">A PSC-dedicated solar simulator should support the following requirements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">Stable irradiance at 1 SUN and low irradiance levels<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Reduced thermal influence on the sample<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Stable light output after shutter opening and closing<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Good reproducibility for repeated measurements<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Suitable effective irradiated area for small PSC samples<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Spectral performance suitable for AM1.5G-based evaluation<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The XES-50S3-PSC is designed based on these practical requirements.<\/p>\n\n\n\n<h2 id=\"anchor-02\" class=\"wp-block-heading has-base-color has-contrast-background-color has-text-color has-background has-link-color has-large-font-size wp-elements-02c80fdf23e775b1ff10346241305532\" style=\"padding-top:var(--wp--preset--spacing--20);padding-right:var(--wp--preset--spacing--20);padding-bottom:var(--wp--preset--spacing--20);padding-left:var(--wp--preset--spacing--20)\">Difference from a conventional solar simulator<\/h2>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">A conventional solar simulator is usually designed to evaluate solar cells under standard conditions, mainly around 1 SUN.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">It is typically evaluated by spectral match, spatial non-uniformity, and temporal instability.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">These are still essential performance items.<br>However, for PSC research, additional practical factors become important. <\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">For example, stable operation at low irradiance is useful when studying light-intensity dependence.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Reduced thermal influence is important when the sample may be affected by temperature rise.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Reproducibility after shutter operation is also important when repeated short-time measurements are performed.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Therefore, the XES-50S3-PSC is not simply a renamed standard solar simulator.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">It is a configuration designed to support the specific measurement conditions required in PSC research.<\/p>\n\n\n\n<h2 id=\"anchor-03\" class=\"wp-block-heading has-base-color has-contrast-background-color has-text-color

features of XES-50S3-PSC<\/h2>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">The XES-50S3-PSC is based on SAN-EI\u2019s xenon solar simulator technology and is optimized for small-area PSC research.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">Main features include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">Effective irradiated

source, the stability over time, and the influence of measurement conditions should also be considered.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">For this reason, SAN-EI provides a technical specification and performance evaluation report for the XES-50S3-PSC.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\">This report includes measured data and explains how the system performs under defined measurement conditions.<\/p>\n\n\n\n<h2 id=\"anchor-05\" class=\"wp-block-heading has-base-color has-contrast-background-color has-text-color
