Springer New York LLC
, 2016 , Article)
In this paper, we report an organic semiconductor based flexible thermogalvanic cell for conversion of heat and light energy into electric power. This thermogalvanic cell has been fabricated using a eco-friendly, affordable ...
Flexible impedance and capacitive tensile load Sensor based on CNT composite
(
Institute of Physics Publishing
, 2016 , Article)
In this paper, the fabrication and investigation of flexible impedance and capacitive tensile load sensors based on carbon nanotube (CNT) composite are reported. On thin rubber substrates, CNTs are deposited from suspension ...
Degradation analysis in mixed (MAPbI3 and MAPbBr3) perovskite solar cells under thermal stress
(
Springer New York LLC
, 2019 , Article)
The current study provides an insight into the thermal stability of perovskite solar cells (PSCs) and the factors causing their degradation. To this end, a systematic stability study was carried out on n-i-p type perovskite ...
