半透明の色素増感太陽電池（DSSC）をアグリボルタイクに活用し、その電力で直接空気回収（DAC）を駆動する構想を、カラチとデービスの2地域で技術経済評価した。DSSCは設置容量が小さいため発電量は少ないが、低い資本費によりLCOEはデービスで10%低い0.29USD/kWh、カラチで0.7%低い0.25USD/kWhとなった。DAC経路次第で年331〜9783トンのCO2除去が可能と試算され、低資本で土地利用両立型の太陽光＋炭素除去経路を示唆する。
English
This study techno-economically assesses semi-transparent dye-sensitized solar cells (DSSCs) for agrivoltaic use, powering direct air capture (DAC) in Karachi and Davis. DSSCs generate less electricity but achieve 10% lower LCOE in Davis (USD 0.29/kWh) and 0.7% lower in Karachi (USD 0.25/kWh) due to lower capex. Depending on DAC pathway, they could remove 331–9,783 tonnes CO2/year, suggesting a low-capital, land-use-compatible solar-plus-carbon-removal route.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農地での営農型太陽光発電（ソーラーシェアリング）とDAC・CCUSの関心が高まっており、土地利用制約下での脱炭素技術の経済性評価として参考になる。ただし開示・SSBJ文脈との直接接点は乏しい。
In the global GX context
Globally, this contributes to the agrivoltaics and DAC literature, offering a techno-economic comparison of semi-transparent PV in contrasting climates. It informs land-use-compatible decarbonization pathways but has limited direct linkage to TCFD/ISSB disclosure frameworks.

📄 Abstract（原文）
The rapid expansion of solar photovoltaics has intensified land-use competition between renewable energy and agriculture, particularly in regions where food security and clean-energy transitions must progress together. Semi-transparent photovoltaic technologies may provide a land-use-compatible pathway for potential agrivoltaic applications by allowing partial light transmission while generating electricity. This study evaluates Dye-Sensitized Solar Cells (DSSCs) as a semi-transparent photovoltaic option and investigates the use of DSSC-generated electricity to power Direct Air Capture (DAC). The scope is limited to photovoltaic-system performance and economics and does not include Photosynthetically Active Radiation (PAR) transmission, crop growth, crop yield, or microclimate analysis. A techno-economic assessment was performed using the System Advisor Model for two contrasting regions, Karachi, Pakistan, and Davis, USA. DSSC and monocrystalline silicon systems were compared over the same land area. Due to their lower installed capacity, the DSSC systems generated less annual electricity. However, their lower assumed capital expenditure resulted in a Levelised Cost of Electricity (LCOE) that was 10% lower in Davis, at US Dollars (USD) 0.29/kWh, and 0.7% lower in Karachi, at USD 0.25/kWh. Based on literature-reported DAC energy requirements, the DSSC systems could support annual Carbon Dioxide (CO2) removal of 331–9707 tonnes in Karachi and 334–9783 tonnes in Davis, depending on the selected DAC pathway. These results indicate that semi-transparent DSSCs may provide a lower-capital, land-use-compatible photovoltaic pathway combined with renewable-electricity-driven carbon removal. Their suitability for practical agrivoltaic deployment requires future PAR-transmission measurements and crop-specific experimental validation.
