Midsummer to begin production of thin film cells in southern Italy after summer
The “largest European thin-film solar cell manufacturing plant” will begin operation after receiving production certification. Midsummer executive Erik Olsson tells pv magazine Italy that production is expected to start after the summer, at a time of sharp increase in demand for thin-film photovoltaic cells from the commercial and industrial solar segment.
First Solar’s unit, Uppsala University present CIGS solar cell with world record efficiency of 23.64%
The new solar cell achieved a maximum power conversion efficiency of 23.75% and a certified efficiency of 23.64%, thus beating the previous world record of 23.35% achieved in 2019 by Japan’s Solar Frontier. The result was confirmed by the Fraunhofer ISE.
Cadmium telluride solar cell based on indium gallium oxide emitter achieves 17.2%
Developed by the University of Toledo, the cell achived the highest efficiency ever reported for flexible cadmium telluride solar cells to date. The device reached an open-circuit voltage of 861 mV, a short-circuit density of 27.8 mA/cm2, and a fill factor of 71.7%.
Thin-film solar is the future of agrivoltaics
In contrast with traditional panels, thin-film solar modules are much more adaptable to these agricultural situations, thanks to their flexible, lightweight design.
Novel approach to build bismuth trisulfide thin-film solar cells
Researchers in Estonia applied for the first time the close-spaced sublimation (CSS) deposition technique to manufacture solar cells based on bismuth trisulfide (Sb2S3). The resulting devices showed limited power conversion efficiency so far, but the scientists claim the new process paves the way for the development of future earth-abundant inorganic PV materials.
Heterojunction design for 26%-efficient copper bismuth oxide thin-film solar cell
Researchers in Bangladesh have simulated a solar cell based on a copper bismuth oxide material, used as an absorber, with n-type cadmium sulfide (CdS) utilized as a buffer layer. In the experiment, the device achieved an efficiency of 26.0%, an open-circuit voltage of 0.97 V, a short-circuit current density of 31.61 milliampere per square centimeter, and a fill factor of 84.58%.
International consortium claims 25% efficiency for perovskite CIGS solar cell
Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.
