Numerical study of lead free CsSn0.5Ge0.5I3 perovskite solar cell by SCAPS-1D
Nalianya, Milimo Amos; Awino, Celline; Barasa, Henry; Odari, Victor; Gaitho, Francis; Omogo, Benard; Mageto, Maxwell (Science Direct, 2021-12)Lead free perovskite solar cells (PCS) are becoming a distinctly predominant area of study due to the toxicity and stability hurdles of the lead halide perovskite. Current lead-free perovskites are also plagued with low ... -
Optimization of Biogas Production in a Batch Laboratory Digester Using Total Solids, Substrate Retention Time, and Mesophilic Temperature
Barasa, Henry; Nyaanga, David; Njue, Musa R.; Matofari, Joseph Wafula (International Journal of Power and Energy Research, 2020-07)Optimization was done by investigating the interaction effects of total solids, mesophilic temperature, and substrate retention time on biogas production in a batch biodigester. The volume of the biodigester was 0.15m3 . ...
