Most of the perovskite (PK)-based photovoltaic (PV) devices are subject to a hysteresis phenomenon when measuring their I-V characteristic. Together with general questions regarding device stability, these hysteresis issues can lead to dramatic overestimation of device performances, which is a challenge for the entire industry. Therefore, CHEOPS has established a measurement procedure and degradation tests with the intention to serve as a standard protocol for academic and industrial development of PK-based PV devices.
In Neuchâtel (Switzerland), CHEOPS researchers from EPFL and CSEM have combined silicon- and perovskite-based solar cells. The resulting efficiency of 25.2% is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30%.
As it has been a tradition for nearly a quarter of a century, once every 4 years, three of world’s most prominent international photovoltaic technical conferences, the Photovoltaic Science and Engineering Conference (PVSEC), the European Photovoltaic Solar Energy Conference (EU PVSEC) and the IEEE Photovoltaic Specialist Conference (IEEE PVSC) merge into a global photovoltaic energy technical forum: The World Conference on Photovoltaic Energy Conversion. In 2018 the WCPEC-7, that combines the 45th IEEE PVSC, the 28th PVSEC and the 34th EU PVSEC, returns to the birth place of the World Conferences and will be held June 10-15, 2018 on the Big Island of Hawaii. CHEOPS will contribute with ...
